4 OS/2 2.0 Tips and Techniques
CHAPTER 3. INSTALLATION CONSIDERATIONS
_______________________________________
This chapter has information about installing OS/2 2.0. For example, it
describes things you might need to consider before, during, or immediately
after installation, such as:
o Upgrading from another operating system
o Reformatting
o Using non-IBM devices, such as a Logitech mouse
o Handling problems during installation.
UPGRADE VERSION OF OS/2 2.0
___________________________
The upgrade version of OS/2 2.0 (for DOS, Windows(**), and OS/2 1.x) is
_
slightly different from the full-purchase-price version of OS/2 2.0. You
must have an operating system installed on your hard disk before you can
install the upgrade version.
If you formatted your hard disk before you attempted to install the upgrade
version (for example, because you purchased a larger hard disk), you must put
an operating system on the hard disk. For example, if your previous
operating system was DOS, start your computer with a DOS diskette, and then
type the following at the DOS command prompt:
FORMAT C: /S
Then proceed with the installation of the upgrade version of OS/2 2.0.
If installation Diskette 1 in your upgrade package is write protected, turn
the diskette over and slide the black tab up at the bottom right side so that
the tab covers the square hole in the diskette. If the tab is missing, place
a piece of tape over the hole. Covering the hole enables information to be
written to the diskette during installation.
REFORMATTING
____________
Following is information about when you should and should not reformat while
you are installing OS/2 2.0.

DURING INSTALLATION
It is a good idea to reformat during the installation of OS/2 2.0.
o You must reformat if you are installing over any beta version 2.0 except
for OS/2 2.0 Limited Availability (6.177H).
o If you formatted during installation, and the installation failed,
reformat.
o If you did not format during installation and the installation failed,
try to install again without formatting. If the installation fails
again, you might want to back up any data files you need from the drive
on which you want to install, and then reformat.
AFTER SUCCESSFUL INSTALLATION
If you successfully install OS/2 2.0, you should NOT install it again unless
you are advised to do so by an IBM dealer or representative. After
installation, you can add any feature you want by double-clicking on OS/2
SYSTEM, SYSTEM SETUP, and then SELECTIVE INSTALL.
LIMITED AVAILABILITY VERSION
____________________________
If you previously installed the OS/2 2.0 Limited Availability version of OS/2
2.0 and installed OS/2 2.0 without reformatting, you must update the OS/2
System Editor and Clipboard Viewer PATH statements in the CONFIG.SYS file.
Change them so they read as follows:
\OS2\APPS\E.EXE
\OS2\APPS\CLIPOS2.EXE
Also, you might not be able to delete existing program associations. If this
occurs, make a copy of the program object that has the associations; then
discard the original.
HPFS
____
Following is information about the memory requirement for the High
Performance File System (HPFS), and how to install it.
DECIDING TO USE
If you are trying to decide whether to use HPFS, consider that it takes
approximately 500KB of system memory. If your machine has 6MB or less of
memory, your system performance will be affected adversely.
6 OS/2 2.0 Tips and Techniques
HPFS SUPPORT NOT ADDED DURING INSTALLATION
Support for HPFS was not added to your system if you installed OS/2 2.0 using
either INSTALL ALL FEATURES or INSTALL PRESELECTED FEATURES, and your system:
o Has 6MB or less of memory, and
o Did not previously have HPFS support.
To install HPFS support after installation of OS/2 2.0, double-click on
SELECTIVE INSTALL in the System Setup folder.
PARTITIONING
____________
It is ideal for OS/2 2.0 to be in a partition by itself, unless you are
installing Dual Boot, in which case you must have DOS on the system before
you install OS/2 2.0.
The OS/2 partition should be approximately 40-50MB if you want the default
installation and the swap drive on the same partition. The less memory you
have, the larger the swap file you need, and, therefore, the larger the
partition should be.
If you partition the drive, you should have at least 2 partitions, one for
OS/2 2.0 and one for your data.
CONFIG.SYS (AUTOMATIC UPDATE)
_____________________________
Some device-driver statements might not be copied to your new CONFIG.SYS file
with a REM statement if you click on AUTOMATICALLY UPDATE CONFIG.SYS AND
AUTOEXEC.BAT during installation. Instead, click on USER EDIT CONFIG.SYS AND
AUTOEXEC.BAT so you can copy your device-driver statements to your new
CONFIG.SYS file.
MOUSE DOES NOT WORK
___________________
Following is information about getting a mouse to work.
MOUSE DRIVER (CHANGING DEFAULT)
During installation, do not make changes in the Mouse window unless it is
displayed while Diskette 2 is in the installation drive. If the Mouse panel
is not displayed for you, OS/2 2.0 has been able to determine the correct
device driver for your mouse.
For example, if you have a Logitech PS/2 mouse or serial mouse-series M, the
installation program will correctly select the PS/2 Style Pointing Device
driver, not the Logitech Serial Mouse driver.
Chapter 3. Installation Considerations 7
LOGITECH MOUSE NOT WORKING AFTER INSTALLATION
If you have a Logitech PS/2 mouse or a Logitech serial mouse, series M, and
it does not work after installation, you might have installed the Logitech
Serial Mouse driver, which is not the correct driver. To select the correct
mouse driver, use the keyboard to select OS/2 SYSTEM, SYSTEM SETUP, SELECTIVE
INSTALL, MOUSE in the System Configuration window, and then OK. Those steps
install the default mouse driver, the PS/2 Style Pointing Device driver, that
is required by those mice.
LOGITECH MOUSE NOT WORKING AFTER DUAL-BOOT SWITCH FROM DOS
If your Logitech mouse is not working on a Dual-Boot system after you run DOS
and switch to OS/2 2.0, your mouse might be running in a mode set by a
DOS-based mouse device driver. To correct the problem, type the following at
the DOS command prompt:
MOUSE PC
This will reset the mouse to a mode that is recognized by OS/2 2.0. Then
type the following:
BOOT /OS2
OS/2 2.0 should start and your mouse should work.
You can perform this procedure automatically by creating a batch file for the
commands you would type ("MOUSE PC" and "BOOT /OS2"). For information about
creating a batch file, refer to the online Master Help Index.
HP MOUSE
To install an HP mouse, do the following:
1. Accept the default mouse driver during the installation of OS/2 2.0.
2. Copy HILMOU.SYS and NOEXBIOS.SYS to the C:\OS2 directory. (Those files
are supplied by Hewlett-Packard.)
3. Modify your CONFIG.SYS file so it contains the following lines in the
order shown:
DEVICE=C:\OS2\NOEXBIOS.SYS
DEVICE=C:\OS2\HILMOU.SYS
DEVICE=C:\OS2\MOUSE.SYS TYPE=HILMOU$
If you do not have the diskette that contains the required files, contact the
dealer from whom you purchased the mouse. Or, you can contact
Hewlett-Packard Company customer service.
8 OS/2 2.0 Tips and Techniques
OTHER MOUSE NOT WORKING AFTER DUAL-BOOT SWITCH FROM DOS
If your mouse works when you first turn on your computer, but it does not
work when you switch from DOS to OS/2, your mouse might be emulating (acting
_________
like) another kind of mouse. For example, your mouse might be emulating a
Logitech mouse. Refer to the documentation that came with your mouse to see
if it has a command for changing the mode. If so, try to reset the mouse to
a mode that is recognized by OS/2 2.0.

PROBLEMS WITH INSTALLATION
__________________________
The following information provides solutions for problems you might encounter
during or after installation. They are:
o Problems at the LOGO screen
o Problems while using specific installation diskettes (they are referenced
by number)
o Messages that are displayed on the screen
o Constant beeping while changing diskettes
o A white screen during or after installation
o Old Version of BIOS
o Patch needed for ZEOS notebook
LOGO SCREEN PROBLEMS
Following are problems that can occur at the LOGO screen during or after
installation.
With OAK Video Adapter (during Installation)
If the installation procedure stops immediately after the LOGO screen is
displayed and you have an OAK video adapter, change the video adapter to
8-bit mode and place it into an 8-bit adapter slot.
If the problem continues, you can change the OS2LDR file with the procedure
that follows. You must have a version of DOS on a DOS diskette or on your
hard disk. To change the OS2LDR file, do the following:
1. Make a backup copy of installation Diskette 1. (You can use the DOS
DISKCOPY command to make the backup.) Do not change the file on your
original OS/2 2.0 installation Diskette 1.
2. Start DOS from diskette or your hard disk.
NOTE: Make sure that DEBUG.COM is on your hard disk.
If DEBUG.COM is on your hard disk, change to the appropriate directory,
if necessary.
3. Insert the backup copy of Diskette 1 in drive A. Type the following at
the DOS command prompt:
DEBUG A:\OS2LDR
and press Enter.
4. Type:
4f7c
and press Enter. "CD." will be displayed.
10 OS/2 2.0 Tips and Techniques
5. Type:
90
and press the Spacebar. "10." will be displayed.
6. Type:
90
and press Enter.
7. To write changes to the file, type:
W
and press Enter.
8. To end the debug procedure, type:
Q
and press Enter. (If you started DOS from a diskette in drive A, remove
the backup copy of Diskette 1 from drive A and insert your DOS diskette
and press Enter. You will see the DOS prompt).
9. Restart the installation of OS/2 2.0 using your modified backup copy of
Diskette 1.
With Future Domain SCSI Controller (after Installation)
If you have a Future Domain 16xx SCSI controller, you might have installed
OS/2 2.0 successfully, but then found a problem the next time you started
OS/2 2.0. If the system stopped running with the LOGO screen displayed,
there might be a conflict with the interrupt settings of your hardware
devices. Check all interrupt-request (IRQ) settings on all your hardware
devices and make sure that each one is using a unique IRQ. Future Domain
controllers are shipped from the factory preset to use IRQ5. IRQ5, however,
is the interrupt that is normally assigned to LPT2. Also, it is common for
IRQ5 to be used by sound or communications adapters. You might not see a
problem immediately because of interrupt conflicts, but eventually they can
cause strange results.
Refer to Chapter 10, "Hardware Considerations" on page 81 for more
information about setting IRQ levels.
Chapter 3. Installation Considerations 11
DISKETTE PROBLEMS BY NUMBER
Following are solutions for problems that occur while you are using specific
installation diskettes during installation (for example, Diskette 1).
o DISKETTE 1 PROBLEM
If the installation procedure stops while Diskette 1 is in the diskette
drive of a non-IBM computer, there might be a problem with the features
of the hard disk drive controller. If the controller has on-board disk
caching, disable the caching. If the controller can do asynchronous
memory refreshes, turn off that feature.
o DISKETTE 3 PROBLEM
If the installation program keeps prompting you to insert Diskette 3, you
__________
have a 1.44MB diskette drive that can work in either IBM PC/XT mode or
IBM PC/AT mode. You need to change the mode from XT to AT by changing
the jumper for pin 34 on your 1.44MB diskette drive. Refer to the
information that came with your computer or diskette drive to find out
how to make the change.
o DISKETTE 6 (PROBLEM AFTER, WITH VGA DISPLAY)
If the installation procedure stops after Diskette 6, the adapter for a
VGA display might be causing the problem. If you have a VGA display,
refer to the Guide to Operations for your VGA adapter. If the adapter
has auto-sense capability, find out how to turn off this feature. If the
adapter has a resolution available other than 640x480, make sure the mode
on the adapter is set to 640x480 mode.
o NO DISKETTE 16 (3.5-INCH INSTALLATION)
If you are installing the 3.5-inch version of OS/2 2.0, and the
installation prompts you to insert Diskette 16, your drive A is not being
recognized as a 1.44MB drive. You must set the Basic Input/Output System
(BIOS) to recognize drive A as 1.44MB. Refer to the documentation that
came with your computer to find out how to do this.
MESSAGES ON SCREEN
Following are solutions you can try when you see specific information
displayed on the screen during installation. For example, there is something
you can do if "C0000005" is displayed when the installation procedure stops.
C0000005 Displayed on Screen
If you see "C0000005" displayed on the screen the first time you start the
system after installation, call the OS/2 Technical Support Center at
800-237-5511 and request a corrected version of the BVHSVGA.DLL file.
12 OS/2 2.0 Tips and Techniques
COUNTRY.SYS File Cannot Be Found
Following are solutions to try when OS/2 2.0 displays a message that it
cannot find the COUNTRY.SYS file
o If you have a PS/2 P70, on PS/2 P70 contact your IBM customer engineer or
computer dealer and request the engineering change announcement "ECA068".
o Find out if a diskette drive or a hard disk drive controller has an
additional device attached to it, such as a tape backup. Disconnect the
device, if possible.
o Make sure the diskette drive or hard disk drive controller resides at its
own IRQ level. Refer to the operations manual that came with your
computer for information about the IRQ setting.
Refer to Chapter 10, "Hardware Considerations" on page 81 for more
information about setting IRQ levels.
SYS1200 and EC=00BF on Screen with Dual Boot
If you see error message "SYS1200" while attempting to Dual Boot to DOS and
you have error code "EC=00BF" (meaning that the DOS environment cannot be
created), check your CONFIG.SYS file. Make sure your virtual DOS device
drivers are listed correctly in your CONFIG.SYS file.
COMPUTER BEEPS CONSTANTLY
If your computer beeps constantly while you are changing diskettes during
installation, you might have a defective diskette drive controller or cable.
Check the controller and cable for damage, and also check all their
connections.
WHITE SCREEN WITH DISK LIGHT ON CONSTANTLY
If you are installing OS/2 2.0 on a fast 486 ISA-bus computer, you might see
a white screen and the disk light constantly on. If so, try switching the
system board out of turbo mode, to reduce the speed of the computer. Refer
to the documentation that came with your computer to find out how to change
the mode.
WHITE SCREEN AFTER INSTALLATION
If the display screen is white after installation and there is no system
activity, set the video adapter to 8 bits and move the adapter to an 8-bit
slot. If possible, disable the auto-switching capability of the video
adapter. Refer to the documentation that came with your video adapter.
Chapter 3. Installation Considerations 13
WHITE SCREEN WITH AN ATI VIDEO ADAPTER
If the display screen is white after installation and you have an ATI 8514
Ultra or Graphics Ultra video adapter, you might have an old version of a
video ROM chip on the adapter. Contact ATI at 416-756-0711 to request an
update.
BIOS
Following is information about systems and system boards that do not support
OS/2 2.0 because of an old version of BIOS. Information is provided about
how to upgrade the BIOS.
Phoenix BIOS
You must have level 1.02.05D, or later, BIOS from Phoenix to run OS/2 2.0.
AMI BIOS
If the installation procedure stops while you are using the first few
installation diskettes, or you see SYS2025 or SYS2027 displayed on the
screen, you might have a problem because of BIOS from American Megatrends,
Inc. (AMI) AMI. To find out, do the following:
1. Watch the screen after you turn on the computer. Look for the name AMI.
2. If the BIOS is from AMI, look for one of the following statements:
o For AMI BIOS and AMI BIOS plus, you will see:
aaaa-bbbb-mmddyy-Kc
o For AMI Hi-Flex BIOS, you will see:
ee-ffff-bbbbbb-gggggggg-mmddyy-hhhhhhhh-c
3. The AMI BIOS must be dated 0509991 or later. In the previous statements,
the BIOS date is indicated by mmddyy. Check your computer screen to see
if the date is acceptable. If the BIOS is an older version, contact the
dealer at your place of purchase for information about upgrading the
BIOS. Or, contact Washburn & Co., the distributors of AMI BIOS products,
at 716-248-3627.
4. If the BIOS has an acceptable date, you might have a problem because the
keyboard controller is an old version. The controller must be version KF
or later (for example, KG). In the previous statements, the keyboard
controller is indicated by Kc and c. Check your computer screen to see
if the keyboard controller is an acceptable version. If it is not,
contact your computer dealer or Washburn & Co..
5. If the BIOS and keyboard controller are acceptable versions, you might
have a problem because your hard disk drive is an old version. Check the
date of manufacture for each hard disk drive.
14 OS/2 2.0 Tips and Techniques
o If you have a hard disk drive from IDE, it must be dated 040990 or
later.
o If you have a hard disk drive from another manufacturer, it must be
dated 092588 or later.
If your hard disk drive is an old version, contact the dealer at your
place of purchase or the manufacturer for information about upgrading the
drive.
Micronics System Board
If your computer does not work properly, you might have revision E of a
Micronics system board. That board contains an old version of BIOS. If you
purchased the board from Gateway, contact Gateway 2000, Inc. at 800-523-2000
and request an upgrade to revision F.
Gateway 2000 Computer
If you have an early version of a Gateway 2000 computer that does not work
properly, your BIOS might be an old version. The company suggests that you
replace the system board. Contact Gateway 2000, Inc. at 800-523-2000 for
information about upgrading your computer.
ZEOS NOTEBOOK
If you have a ZEOS notebook and the installation of OS/2 2.0 fails, you can
correct the installation problem by adding a patch to your Installation
Diskette.
NOTE: To do this, you must use a computer that has OS/2 2.0 running on it.
Ask a local IBM dealer, a friend, or a co-worker if you can use their
computer for a few minutes. Take your OS/2 2.0 Installation Diskette
and a blank, formatted, high-density 3.5-inch diskette with you.
If you are unable to find a computer to use, call the OS/2 Technical Support
Center at 800-237-5511 and request that a patched Installation Diskette be
sent to you.
To install the patch using a computer that has OS/2 2.0 running on it, do the
following:
1. Double-click on OS/2 SYSTEM on the OS/2 desktop.
2. Double-click on COMMAND PROMPTS.
3. Double click on OS/2 WINDOW. You will see an OS/2 command prompt.
4. Back up your Installation Diskette to the blank 3.5-inch diskette you
brought with you by typing the following:
DISKCOPY A: A:
Then press Enter and follow the prompts.
5. Place the newly created backup Installation Diskette in drive A.
Chapter 3. Installation Considerations 15
6. Type:
PATCH SYSINSTX.COM
Then press Enter.
7. When asked for the offset address, type:
96AF
Then press Enter.
8. Change "44" to "45"; then press Enter. The following message is
displayed:
Do you wish to continue patching sysinstx.com?
9. Type:
N
Then press Enter.
10. When asked if you want to apply patches, type:
Y
Then press Enter.
11. At the OS/2 command prompt, type:
SYSINSTX A:
The patch is complete.
12. Install OS/2 on your ZEOS using the patched backup Installation Diskette
that you just created.
SHORT CUT IF YOUR INSTALLATION PROCEDURE STOPS
______________________________________________
If the installation procedure stops before completion, you might be able to
complete the installation without reusing all the installation diskettes.
You do not have to use all diskettes again if the installation stopped after
you were prompted to put the Installation Diskette in the drive the second
time (after you are in the graphical installation). For example, if you were
copying files from Diskette 9 on a 3.5-inch-diskette system, you could resume
the installation at Diskette 9 after doing the following:
1. Identify which diskette was being "unpacked" when the installation
procedure stopped.
2. Subtract the number of that diskette from 15 and add one to the result if
you have 3.5-inch installation diskettes. (Subtract the number from 18
if you have 5.25-inch installation diskettes.) For example, if you were
on Diskette 9 on a 3.5-inch system, the result would be 7.
3. Start the computer with the Installation Diskette, and then insert
Diskette 1 when prompted.
16 OS/2 2.0 Tips and Techniques
4. When you are asked to press Esc to cancel, press Esc. You will see a
command prompt.
5. Use a text editor to edit the CONFIG.SYS file on your hard disk.
6. In the line that starts with FIRSTDISK, change the number to the number
of the diskette that was in the diskette drive when the installation
procedure stopped. In the example, this is 9.
_
FIRSTDISK=9
7. In the line that starts with NUMDISKS, change the number to the one you
reached in step 2. In the example, this is 7.
_
NUMDISKS=7
8. Remove the diskette and press Ctrl+Alt+Del. You will see the graphical
install panel. Click on OK, then INSTALL, and select all defaults.
9. When you are prompted, insert the diskette named in the prompt. In the
example, this would be Diskette 9, the diskette that was being loaded
when the installation procedure stopped.
All the Selective Install choices that you selected when you first tried to
install OS/2 2.0 are preserved.
APPLICATIONS
____________
Following is information about running DOS or Windows applications, or
Windows Version 3.1. You can also find out what to do if any of your
previous applications did not migrate during installation.
DOS OR WINDOWS APPLICATIONS (BEFORE RUNNING)
After installation, and before you run any DOS or Windows applications, shut
down your system and restart it. You only have to do this once, immediately
after you finish installing OS/2 2.0.
PREVIOUS APPLICATION NOT MIGRATED
Occasionally, the Migrate Applications program might not find all
applications. In this case, retry the Find Programs operation.
WINDOWS VERSION 3.1
IBM's testing of Windows Version 3.1 environment indicates that the OS/2 2.0
Chapter 3. Installation Considerations 17
Installation program will not configure your WIN-OS/2(*) desktop. If the
Windows directory that is found is from a Windows Version 3.1 environment,
either change the DOS PATH to point to a Windows Version 3.0 environment, or
select the default environment.
CD-ROM (SELECTIVE INSTALL)
__________________________
If you install CD-ROM using the SELECTIVE INSTALL program, do not install any
other options at the same time.
UNDELETE (ENABLING)
___________________
To enable the UNDELETE command, delete "REM" from the beginning of the
following statement in the CONFIG.SYS file:
REM SET DELDIR=
DUAL BOOT DOES NOT WORK
_______________________
If you cannot dual boot (switch from DOS to OS/2 by typing "Boot /OS2"), you
might have one or more active TSR (terminate and stay resident) or DOS cache
programs. If so, end the programs before you switch to DOS.
BOOT MANAGER
____________
Following is information about using the Boot Manager.
BOOT MANAGER MENU BYPASS
The Setboot utility program supports an immediate-restart function that will
restart the system to the specified drive without going through the Boot
Manager Menu. The parameter is /IBD:DRIVE, where DRIVE is the letter of a
startable partition. For example, from the OS/2 command prompt, you can type
SETBOOT /IBD:E
to start the logical drive E without displaying the Boot Manager Menu. (If
the Boot Manager is not present, then only drive C can be specified.)
BOOT MANAGER WITH DUAL BOOT OS/2 VERSION 1.3 IN A PARTITION
If you are using Boot Manager, and one of your partitions contains OS/2
Version 1.3 with Dual Boot, copy BOOT.COM from the OS/2 2.0 \OS2 subdirectory
to the OS/2 Version 1.3 \OS2 subdirectory.

NON-IBM COMPUTER WITH TWO DRIVES
________________________________
If you have a non-IBM computer with two hard disk drives (for example, an IDE
and a WD 506 clone), the second drive might not work properly after you
install OS/2 2.0. If so, reformat that drive with DOS or OS/2 2.0.
Chapter 3. Installation Considerations 19
20 OS/2 2.0 Tips and Techniques
CHAPTER 4. OS/2 WORKPLACE SHELL
________________________________
This chapter describes tips you might find useful when using the OS/2
Workplace Shell(*). For WIN-OS/2-specific topics, you should also refer to
Chapter 8, "Windows Version 3.0 Programs Support" on page 65.
STARTING UP YOUR SYSTEM
_______________________
o If you are using the file allocation table (FAT) file system, you should
update your CONFIG.SYS file with the following statement to auto-check
drive C (or your startable partition):
DISKCACHE=64,LW /AC:C
NOTE: This function is done automatically in the High Performance File
System (HPFS).
o The Startup folder is the OS/2 Workplace Shell equivalent of the
STARTUP.CMD file. Objects placed in a startup folder are started when
the Desktop folder is opened. You cannot guarantee the order in which
the objects are started.
NOTE: Place program objects in this folder instead of the executable
program-file objects.
o If you want to prevent programs from automatically starting when the
computer is restarted (for example, programs located in the Startup
folder or programs that were running at the time the computer was shut
down), do the following:
1. Press Ctrl+Alt+Del to restart the computer.
2. When the mouse pointer appears, press Ctrl+Shift+F1.
3. Hold the keys for approximately 15 seconds, or until the desktop
icons appear. (If the hard disk light stops during this time, your
computer might be suspended. Release the keys quickly, and then
resume holding the keys until the desktop icons appear.)
o The STARTUP.CMD file is started before the OS/2 Workplace Shell is
started; therefore, you cannot start applications using this file if they
require an initialized shell.
o If you want a customized system startup, you can update your CONFIG.SYS
file with the following statements:
- SET RESTARTOBJECTS =
---------------
(*) Trademark of the IBM Corporation.
(C) Copyright IBM Corp. 1992 21
YES Default. Start all objects that were
running at time of shutdown.
NO Do not start any applications that were
running at time of shutdown.
STARTUPFOLDERSONLY Start objects only in the Startup folder.
REBOOTONLY Start objects only if the OS/2 Workplace
Shell is starting after resetting with
Ctrl+Alt+Del or turning on the computer.
This parameter can be used with one of the
other parameters (for example, YES).
NOTE: In preparation for a situation where a faulty application
suspends your computer, you might want to add the REM SET
RESTARTOBJECTS=NO statement to your CONFIG.SYS file. Then,
should an application fail to function, you can restart your
system using the OS/2 Installation diskette, and then edit the
CONFIG.SYS file and activate the statement by removing the
word REM. When you restart your computer, the faulty
application (and all others) are kept from restarting.
- SET AUTOSTART =
FOLDERS Folders are opened, including the Desktop folder.
TASKLIST The Window List is opened.
PROGRAMS Programs are opened.
CONNECTIONS Re-creates the network connections established
when you last logged on.
NOTE: This option is used to start parts of the OS/2 Workplace
Shell. Eliminating any of the above in the list restricts
users from accessing portions of the shell (for example,
limiting a user to only a few applications).
USING THE SHELL
_______________
ICONS, TABS, OR BIT MAPS DO NOT APPEAR
o Because of device-resource limitations, when too many applications are
open, or when too many bit maps are visible on the screen, new icons,
tabs, or other bit maps might not be drawn. To fix this situation, close
unused folders and applications so their device resources can be used by
other processes.
o If some system icons (such as OS/2 System or Shredder) do not appear when
you start the operating system, you can reset the desktop to its default
configuration by doing the following:
WARNING: THIS PROCEDURE REMOVES ANY DESKTOP CUSTOMIZATION DONE SINCE
INSTALLING THE OPERATING SYSTEM.
1. Press Ctrl+Alt+Del to restart the computer.
2. Before the OS/2 Logo panel appears, hold down Alt+F1 for 20 seconds.
22 OS/2 2.0 Tips and Techniques
The current versions of the CONFIG.SYS, OS2.INI, and OS2SYS.INI files are
renamed and replaced by the default installation versions in the
\OS2\INSTALL subdirectory. If you have a STARTUP.CMD file, it also is
renamed. This deactivates the startup feature.
RESTORING THE DESKTOP
If your desktop becomes damaged (for example, if you start a specific version
of DOS and rearrange your hard disk, damaging either INI files or extended
attributes), you must restore the initial INI and CONFIG.SYS files to restore
the desktop. However, any modifications (such as shadows and associations
created after installation) are lost and must be re-created. To restore the
desktop, do the following to update your existing INI files:
1. Restart your computer using the OS/2 Installation Diskette; then insert
Diskette 1.
2. Press Esc to access an OS/2 full screen; then change to the \OS2
directory.
3. Type
MAKEINI OS2.INI INI.RC (and press Enter)
MAKEINI OS2SYS.INI INISYS.RC (and press Enter)
4. Delete the hidden file WP ROOT. SF in the startable partition. Type:
ATTRIB -h -s -r "WP ROOT. SF" (HPFS) (and press Enter)
or
ATTRIB -h -s -r WP_ROOT._SF (FAT) (and press Enter)
Type:
DEL "WP ROOT. SF" (HPFS) (and press Enter)
or
DEL WP_ROOT._SF (FAT) (and press Enter)
If the above procedure does not fix the problem, do the following to recover
the backup INI files. You will lose all your information, but the system
should be restored.
1. Press Ctrl+Alt+Del to restart your computer.
2. As soon as you hear a single beep, or you press Enter at the Boot Manager
menu or power-on password prompt, press and hold Alt+F1. Hold these keys
down until you hear rapid beeping.
If the preceding procedures do not fix the damaged desktop, do the following
to re-create the INI files:
1. Restart your system using the OS/2 Installation Diskette; then insert
Diskette 1.
2. Press Esc to access an OS/2 full screen; then change to the \OS2
directory.
Chapter 4. OS/2 Workplace Shell 23
3. Delete the current INI files. Type:
DEL OS2.INI (and press Enter)
DEL OS2SYS.INI (and press Enter)
4. Re-create both files using the MAKEINI command. Type:
MAKEINI OS2.INI INI.RC (and press Enter)
MAKEINI OS2SYS.INI INISYS.RC (and press Enter)
5. Change to the desktop directory, OS!2_2.0_D (FAT) or "OS!2 2.0 DESKTOP"
(HPFS).
6. Delete all subfolders (subdirectories) in this directory.
7. Change to the root directory.
8. Delete the hidden file WP ROOT. SF in the startable partition. Type:
ATTRIB -h -s -r "WP ROOT. SF" (HPFS) (and press Enter)
or
ATTRIB -h -s -r WP_ROOT._SF (FAT) (and press Enter)
Type:
DEL "WP ROOT. SF" (HPFS) (and press Enter)
or
DEL WP_ROOT._SF (FAT) (and press Enter)
9. Press Ctrl+Alt+Del. The desktop is reinstalled to its initial
installation setup.
10. Shut down the system using the SHUT DOWN choice on the desktop pop-up
menu.
NOTE: Use MAKEINI instead of the Alt+F1 key combination if you do not want
to replace the CONFIG.SYS file and desktop. The install process
places a copy of the original OS2.INI, OS2SYS.INI, and CONFIG.SYS
files in the \OS2\INSTALL subdirectory. These are the same INI files
created with MAKEINI. They will rebuild the desktop and set it to its
initial installed state.
Alt+F1 replaces OS2.INI, OS2SYS.INI, and the CONFIG.SYS files.
RECOVERING ICONS
o If you lose a folder by moving it to a folder you are unable to access,
you can recover the folder. From an OS/2 Window, use the MOVE command to
relocate the folder (for example, the OS/2 System folder, "OS!2_SYS."),
to the proper location.
WARNING: THE FOLLOWING PROCEDURE SHOULD BE USED ONLY IF A FOLDER IS
INACCESSIBLE TO THE OS/2 WORKPLACE SHELL.
24 OS/2 2.0 Tips and Techniques
To move a folder (for example, the "OS!2_SYS" folder):
1. Change to the directory where the "OS!2_SYS" folder is located.
2. Type the following to move the folder back to the Desktop folder:
MOVE OS!2_SYS \OS!2_2.0_D (FAT)
(or)
MOVE "OS!2 SYSTEM" \"OS!2 2.0 DESKTOP" (HPFS)
o If, intermittently, the icons on your desktop open normally but appear
black, there might have been a timing problem that occurred when a new
icon was saved using the General page in the settings notebook. Try
correcting the appearance by re-creating or re-storing the icon.
USING EXECUTABLE FILES
It is not recommended that you move program-file objects (.EXE, .COM, .CMD,
and .BAT) from their installed directories (for example, moving a
program-file object from the Drives folder to a new location). Instead, you
should create a new object that refers to the original, either a program
object or a shadow; then you can move the new object to a location of your
choice. (Program-object settings and shadow settings specify the location of
the original program-file object.) To create a program object or shadow:
1. Display the pop-up menu for the program-file object by moving the mouse
pointer to it and clicking mouse button 2.
2. Click on CREATE ANOTHER or CREATE SHADOW.
3. Click on a folder for the new object; then click on CREATE.
NOTE: The CREATE ANOTHER choice, when used on a program-file object, creates
a program object, not a program-file object.
CREATING AN ICON FOR AN APPLICATION
If you want to create an icon for a DOS, Windows, or OS/2 application that
does not have one, but has graphics within the application, do the following:
1. Run the application in a window session.
2. When you see an icon-sized graphic that you would like to use as the icon
to represent your program, size the window, making the image
approximately the size of a desktop icon.
3. Click on the title-bar icon (in the upper-left corner of the window);
click on MARK.
4. Mark the graphic.
5. Click on COPY to move the graphic to the clipboard.
6. Display the pop-up menu for the object by moving the mouse pointer to it
and clicking mouse button 2.
7. Click on the arrow to the right of OPEN.
Chapter 4. OS/2 Workplace Shell 25
8. Click on SETTINGS; then click on the GENERAL tab to display the default
icon.
9. Click on CREATE ANOTHER to display the Icon Editor.
10. Click on FILE, click on NEW, click on ICON; then click on OK.
11. Click on EDIT, then PASTE to paste in your graphic. If necessary, use
the Icon Editor to make any changes you want in the graphic.
12. Click on FILE, then SAVE to store the program name.ICO file in the same
drive and directory as the program file (.COM or .EXE file).
13. Double-click on the title-bar icon to exit the editor.
14. From the settings notebook, click on FIND; then locate the saved .ICO
file. (Clicking on DRIVES is the easiest search.)
15. Click on the icon; then save the file.
16. Exit the settings notebook. The original icon is replaced with the
graphic from the application.
CHANGING THE COLOR OF ICON TITLE-TEXT
If you want to change the color of the title-text of all the icons in a
folder, do the following:
1. Double-click on OS/2 SYSTEM.
2. Double-click on SYSTEM SETUP.
3. Double-click on COLOR PALETTE.
4. Press and hold Ctrl; then, pressing and holding mouse button 2, drag a
color to an icon. Drop the color; then release Ctrl.
NOTE: You cannot change the color of individual icon-title text.
ADDING AN OS/2 WINDOW TO THE DESKTOP MENU
If you want another method of accessing an OS/2 Window, you can add OS/2
WINDOW as a new menu choice on the desktop pop-up menu. Do the following:
1. Display the pop-up menu for the Desktop folder by clicking mouse button 2
on an area not covered by any objects or windows.
2. Click on the arrow to the right of OPEN.
3. Click on SETTINGS; then click on the MENU tab.
4. From the ACTIONS ON MENU choices, click on CREATE ANOTHER.
5. In the Menu item name field, type OS/2 WINDOW.
6. In the PROGRAM NAME field, type C:\OS2\CMD.EXE (change to a different
drive, if necessary).
7. Click on OK.
8. Double-click on the title-bar icon to close the notebook.
9. Display the Desktop folder pop-up menu again. "OS/2 Window" is added to
the available menu choices. If you click on this choice, an OS/2 Window
is displayed.
26 OS/2 2.0 Tips and Techniques
CHANGING A DEFAULT FOLDER VIEW
If you want to change the default view for displaying the objects within a
folder (for example, icon versus details view), do the following:
1. Display the pop-up menu for the folder by moving the mouse pointer to it
and clicking mouse button 2.
2. Click on the arrow to the right of OPEN.
3. Click on SETTINGS; then click on the MENU tab.
4. Click on OPEN in the AVAILABLE MENUS field. The Menu Settings window is
displayed.
5. In the DEFAULT ACTION field, click on the default you want.
6. Click on OK.
USING THE MINIMIZED WINDOW VIEWER
o In the Minimized Window Viewer settings notebook, disregard Page 1 of 3.
Each section of the notebook contains 1 page only.
o Some objects, such as WIN-OS/2 programs, online books, and programs that
start other programs, do not always minimize to the Minimized Window
Viewer.
USING FIND
o In the Help information for Find, disregard any references to page 2.
Page 2 does not exist in Find operations.
o If you change the title of an object from within the Find Results folder,
the name of the original object is changed.
RECEIVING AN INCORRECT DOS VERSION MESSAGE
If you receive the message "Incorrect DOS version" when trying to run a DOS
application under OS/2 2.0, the application is using an old level of DOS on
your computer. To fix the problem, update the DOS setting DOS_VERSION.
RECEIVING A SYS3176 MESSAGE
If you receive the message "SYS3176" whenever you attempt to open a DOS
session or DOS application, refer to the section on SVGA support in
Chapter 9, "Video/Graphic Support" on page 71. Additionally, try the
following:
1. In your CONFIG.SYS file, set RMSIZE to 624 instead of 640.
2. Change the DOS setting for the object to "HW_ROM_TO_RAM to ON."
Chapter 4. OS/2 Workplace Shell 27
USING ANSI COLORS AND CHARACTERS IN DOS SESSIONS
________________________________________________
If you want to use ANSI colors and characters in your DOS sessions, do the
following:
1. Add this statement to your CONFIG.SYS file.
DEVICE=C:\OS2\MDOS\ANSI.SYS
2. Shut down your computer.
3. Press Ctrl+Alt+Del to restart your computer and make the change active.
USING HPFS
__________
o If you formatted your installation drive with HPFS, you might not be able
to access files in the Desktop folder from DOS or WIN-OS/2 applications.
DOS and WIN-OS/2 applications use the FAT file system.
o If you are typing a command in the HPFS, you must include double
quotation marks around the name of the subdirectory or file name if it
contains blanks. For example, to change to the OS!2 2.0 Desktop
directory, type:
CD "OS!2 2.0 DESKTOP"
As another example, to copy the file This is my file from the root
directory to the This is my directory subdirectory, type:
COPY "THIS IS MY FILE" \"THIS IS MY DIRECTORY"
NOTE: In the FAT file system, HPFS file names are shortened. Underscores
represent blank spaces.
SHUTTING DOWN
_____________
o In some low-resource situations, the final shutdown message might not
appear after a shutdown is performed. To ensure that shutdown is
complete, wait until all disk activity stops before turning off or
restarting your computer by pressing Ctrl+Alt+Del.
o If you want to shut down your system without using a mouse, do the
following:
1. Press Ctrl+Esc to display the Window List.
2. Press Up Arrow (A) to move the cursor to "OS/2 2.0 Desktop - Icon
View"; then press Enter.
3. Press Ctrl+\ to deselect any selected icons.
4. Press Shift+F10 to display the pop-up menu for the desktop.
5. Press Down Arrow (V) to move the cursor to SHUT DOWN; then press
Enter.
28 OS/2 2.0 Tips and Techniques
o You should shut down your system before restarting or turning off your
computer; however, there are situations where you might want to restart
your system by pressing Ctrl+Alt+Del instead:
- If you used the ARRANGE choice on the Desktop folder pop-up menu, it
rearranged the icons you placed in specific positions on the screen.
Restarting your system recovers your icon positions.
- If you opened several folders containing many icons, shut down will
take a long time saving the positions of the icons. You might want
to restart your system without doing a shut down as long as you are
certain that you will not lose anything else of importance.
o If you shut down your system, but do not receive the message "Shutdown
has completed. It is now safe to turn of your computer...", you should
wait for all disk activity to stop, and then you can press Ctrl+Alt+Del.

CHAPTER 5. PRINTING CONSIDERATIONS
___________________________________
This chapter describes tips for configuring your print hardware, as well as
information to help you diagnose printing problems.
CONFIGURING YOUR COMPUTER FOR PRINTING
______________________________________
On most AT bus (ISA) parallel ports, the configuration is done by either
dual-inline package (DIP) switches or jumper settings. Most of the systems
and adapters purchased have literature that explains the interrupt request
(IRQ) level and port setting for each port. The following are standard
parallel-port address and IRQ settings:
Two-parallel-port hardware setup:
AT EISA/MC
_________ ________
3BC/IRQ7 LPT1 3BC/IRQ7
278/IRQ5 LPT2 378/IRQ7
or
378/IRQ7 LPT1 378/IRQ7
278/IRQ5 LPT2 278/IRQ7
Three-parallel-port hardware setup:
AT EISA/MC
_________ ________
3BC/IRQ7 LPT1 3BC/IRQ7
378/IRQ7 LPT2 378/IRQ7
278/IRQ5 LPT3 278/IRQ7
Dip switches and jumper settings reside on the system board or adapter in
your computer. To change their configuration, do the following:
1. Turn off your computer.
2. Remove the parallel-port adapter.
3. Configure the adapter on the board or card by adjusting the DIP switches
and/or jumpers to set the parallel port to one of the industry standard
combinations. Ensure that other adapters are not configured to use the
same IRQ level (for example, the one assigned to the printer port).
Sound, Musical Instrument Device Interface (MIDI), LAN, and serial
adapters might be sharing these same hardware-interrupt levels and
creating interference.
(C) Copyright IBM Corp. 1992 31
For more information, refer to "Setting the Interrupt Request (IRQ) Level on
an ISA System" on page 90 and "Interrupt Problems on an ISA System" on
page 89.
HARDWARE ADAPTERS AND IRQ CONFLICTS
AT bus (ISA) computers do not allow hardware-interrupt sharing; therefore,
each adapter must be configured to a separate IRQ level to be able to work
properly. Some adapters, such as SoundBlaster, are factory configured to
IRQ7, or their accompanying instructions recommend that you configure them to
IRQ7. This might be the same hardware-interrupt level as the first parallel
port. If you intend to print, this conflict must be resolved. You might be
able to use IRQ10 with SoundBlaster because it does not conflict with
parallel ports (IRQ7,IRQ5) or IRQ5 if LPT2 is not being used. Refer to
"Configuring Your Computer for Printing" on page 31 and "Setting the
Interrupt Request (IRQ) Level on an ISA System" on page 90 for more
information about possible parallel-port and IRQ settings.
Refer to the reference manual for your adapters to configure the IRQ levels
for your parallel-ports (could be on the system board) and other adapters in
your system.
PS/2 DIRECT-MEMORY-ACCESS PARALLEL PORTS
If you have a Personal System/2(*) system that supports direct-memory-access
(DMA) parallel ports, OS/2 2.0 can take advantage of it. The current systems
with a DMA parallel port include PS/2 models 56, 57, 80-A21, 80-A31, 90, and
95. If you have one of these systems, ensure that the parallel-port
arbitration level is set to SHARED7 (enabled). OS/2 2.0 will automatically
take advantage of this feature; no additional OS/2 setup is required. If you
are an OS/2 Version 1.3 customer with Corrective Service Diskette 5054 (or
later) installed, and you have disabled the parallel-port arbitration level,
you need to re-enable it in order for OS/2 2.0 to take advantage of the
feature. Use the Reference Diskette shipped with the computer to view the
system configuration, and then set the parallel-port arbitration level to
SHARED7.

printer driver from the OS/2 Workplace Shell printer object, and respond YES
when asked if the driver files should be deleted from the hard disk.
HP PAINTJET AND PAINTJET XL PRINTERS
These printers should use the Micrografx Paintjet printer driver
(SMGXPJET.DRV) shipped with OS/2 2.0 on Printer Diskette 3.
Some applications, such as Aldus PageMaker, have problems printing multiple
bit maps using this printer driver. If this occurs after the driver is
installed, open the printer object settings notebook; then select
PRINTER-SPECIFIC FORMAT on the Queues page.
IBM 3812, 3852, 5152, 5182, 5201-1, AND 5216 PRINTERS
Printer drivers were not shipped with OS/2 2.0 for IBM 3812, IBM 3852, IBM
5152, IBM 5182, IBM 5201-1, or IBM 5216 printers because they have been out
of service for several years. However, you can use the printer drivers
shipped with OS/2 Version 1.3. Download the printer drivers from CompuServe
(located in Library 17), or use the IBM Electronic Device Driver Distribution
system. (Refer to the order card in the OS/2 2.0 package.)
NOTE: The IBM 3812 printer can use the IBM 5152 printer driver by selecting
5152 compatibility mode in the 3812 printer. (For more information,

DIAGNOSING PRINTING PROBLEMS
____________________________
This section describes the actions you can take to resolve some common
printing problems.
SLOW PRINTING
If you have an AT bus (ISA) computer and your parallel printer prints slowly
under OS/2, DOS, and WIN-OS/2 sessions, your parallel-port address and
hardware-interrupt levels are not configured correctly. You need to
reconfigure your hardware. Refer to "Configuring Your Computer for Printing"
on page 31.
UNABLE TO PRINT
If you encounter printing problems with parallel ports (for example, nothing
prints), ensure that you have installed the appropriate printer driver for
your model printer. If the printer driver is correct, check the following:
o Check that your parallel ports are configured properly. Refer to
"Configuring Your Computer for Printing" on page 31 for configuration
settings.
o Verify that your printer cable meets parallel-port specifications. Some
cables do not meet these specifications and can cause printing problems.
(Cables that are longer than six feet in length are suspect. The
six-foot cable-length problem is more evident on high-speed
microprocessor systems.) Some cable manufacturers reduce the costs of
their cables by not wiring all interface signals. This might not have
been a problem under DOS, because DOS does not make use of all the
signals within the parallel-port interface. However, some interface
signals used to transmit data under OS/2 2.0 are not used when printing
under DOS.
Chapter 5. Printing Considerations 35
You might need to purchase a new cable. You might want to use an "IBM
approved" cable, one which has been verified as properly wired.
o If you still cannot print, and you are convinced it is not a
printer-driver problem, interrupt problem, or cable problem, there might
be a problem with your I/O adapter. Some older parallel-port adapters
fail to generate hardware interrupts; therefore, they will not work with
versions of the OS/2 operating system. These adapters usually work
correctly under DOS, as DOS does not use hardware interrupts to print.
The OS/2 2.0 operating system waits for the printer to send an interrupt
when the printer is ready for more data. If your adapter does not
generate interrupts, it must be replaced if you want to print under OS/2
2.0. If your printer-buffer light illuminates, or prints one character
and then displays an error message (or otherwise behaves erratically),
you might have an interrupt problem.
PRINTER STOPS PRINTING
If your DOS application sending PostScript output stops printing, do the
following:
1. Cancel the print job that caused the printer to stop printing.
2. Open the printer-object settings notebook to the Queue page.
3. Turn off the PRINT WHILE SPOOLING check box.
4. Resend the print job.
ATTEMPT TO PRINT TO AN OFF-LINE PRINTER
If you send a print job to an off-line printer, and then retry the operation
while the printer is online by responding to the Retry message, your job
might be damaged. To fix the problem, cancel the initial job, and resubmit
it after resetting the printer.
PRINTER WORKED UNDER DOS, BUT NOT UNDER OS/2 2.0
If your printer worked under DOS, but does not work under OS/2 2.0, there is
probably a problem with your hardware-interrupt level or printer cable.
(Refer to "Unable to Print" on page 35.)
PRINT JOB SPOOLED BUT DOES NOT PRINT
The spooler will not print a job until the application closes the print-data
stream. Some DOS applications do not immediately close the print-data
stream. If you see your print job as an icon with an arrow pointing to the
document in the Job Icon View window, the job will not print. The arrow must
point from the document to the print device. This will not occur until the
application closes the data stream.
If the job does not print after 15 seconds, you might need to change a DOS
setting. By default, the PRINT_TIMEOUT DOS setting is turned ON and set to
36 OS/2 2.0 Tips and Techniques
15 seconds. If, after 15 seconds, your job does not print, adjust the
setting. (Refer to "Printing Starts Only When DOS Application Stops" on
page 37 regarding the LPTDD.SYS file.)
PRINTING STARTS ONLY WHEN DOS APPLICATION STOPS
If your DOS print job does not begin printing until the application is
stopped, the application has not closed the data stream. Use the DOS_DEVICE
DOS setting to load the C:\OS2\MDOS\LPTDD.SYS device driver. Then, the
PRINT_TIMEOUT DOS setting can be used to close the print job without having
to exit your application.
PRINT JOB SPLIT INTO SEVERAL SPOOL FILES
If your DOS application print job is split into several spool files, you
might need to disable the spooler to correct the problem. Some applications
open and close the printer data stream for every character, line, or page.
Disabling the spooler (using the Spooler object in the System Setup folder)
is one way to correct this problem. Another alternative is to upgrade the
application by contacting the manufacturer. If the problem occurs with
complex printouts, you might increase the DOS setting PRINT_TIMEOUT value.
CAN PRINT FROM DOS APPLICATION, BUT CANNOT PRINT ELSEWHERE
If you are printing from a DOS application, but are unable to print elsewhere
until you stop the DOS application, your DOS application is accessing the
parallel-port hardware directly. OS/2 2.0 prevents two or more applications
from simultaneously accessing the same parallel-port hardware. The second
application must wait for the first application to stop, even if the second
application is the OS/2 print object.
PRINTER WORKED UNDER WINDOWS, BUT NOT UNDER OS/2 2.0
o If your printer worked under a Windows operation, but does not work after
installing OS/2 2.0, delete the printer driver and reinstall it under
WIN-OS/2 using the WIN-OS/2 Control Panel.
o If printing from a WIN-OS/2 session is slow, but acceptable everywhere in
the system, you might need to set the priority level higher using the
Options menu in the WIN-OS/2 Print Manager.
PRINTING FROM A WIN-OS/2 SESSION
________________________________
The following section describes considerations for customizing your system to
print from a WIN-OS/2 session.
Chapter 5. Printing Considerations 37
LPTX AND LPTX.OS2 PORT CONSIDERATIONS
If your printer is connected to LPTx or LPTx.OS2, be sure that the OS/2
spooler is active and the WIN-OS/2 printer does not use the Print Manager.
(Disable using the Printer icon in the WIN-OS/2 Control Panel.) When the
OS/2 spooler is active, WIN-OS/2 applications print directly to the OS/2
spooler. Therefore, multiple print jobs can be spooled from one WIN-OS/2
session or multiple WIN-OS/2 sessions. This does not apply to serial
printers, because there is no spooling for COM devices to the OS/2 spooler
(only to WIN-OS/2 Print Manager). If you are using LPTx but are unable to
print from any other session, you must use LPTx.OS2 for WIN-OS/2 printing.
If you are printing to a redirected port, you must use LPTx.OS2.
_
OBTAINING AN LPT3.OS2 DESTINATION
To enable support for LPT3.OS2, you need to configure an LPT3.OS2 destination
that you can select from the ports listbox in the WIN-OS/2 Control Panel.
You must shutdown your WIN-OS/2 session and edit the
C:\OS2\MDOS\WINOS2\WIN.INI file. You need to add a "LPT3.OS2=" line
following the "LPT2.OS2=" line in the ports section of the file. After
saving the file, you can start the WIN-OS/2 session and Control Panel and
then select the LPT3.OS2 destination.
INSTALLING THE IBM 4029 LASER PRINTER
o If you are installing the IBM4029 Windows PostScript printer driver for
use in WIN-OS/2 sessions, do the following to avoid an invalid entry in
the WIN.INI file.
1. Double-click on CONTROL PANEL in the WIN-OS/2 session.
2. Double-click on PRINTERS.
3. Click on ADD PRINTER.
4. Click on UNLISTED PRINTER from the list of printers.
5. Insert Printer Driver Diskette 4 in drive A.
6. In the Files and Directories window, click on A.
7. Click on PSCRIPT.DRV from the files list. (The PostScript driver is
installed.)
8. Click on CONFIGURE.
9. Click on the appropriate port.
10. Click on SETUP.
11. Click on IBM4029 (17 font, 600 dpi) from the list of printers.
12. Click on OK several times to remove the open windows.
13. Exit the Control Panel.
14. Save any changes; then exit the WIN-OS/2 session.
o If you have problems printing with a 4029 printer in a WIN-OS2 session,
change the WIN.INI file in the OS2\MDOS\WINOS2 directory. Several lines
in the file refer to the 4029 printer (for example, "IBM 4029 v52.3 (17
Fonts, 600 Dpi"). Change the comma (,) to a colon (:).

o To improve the performance of viewing the contents of a network printer
object, use a long refresh interval or set the interval to 0 (no
refresh).
o If you move the network object from the desktop to another folder, the
network printer-object template will not appear the next time you start
the system. To make it reappear, move the network object back to the
desktop and restart the system.
o If you are unable to print from a DOS session to an LPT port that is
redirected to a network printer, you might need to use the LPTDD.SYS
device driver. (Refer to "Printing Starts Only When DOS Application
Stops" on page 37 for more information.)

40 OS/2 2.0 Tips and Techniques
CHAPTER 6. APPLICATION CONSIDERATIONS
______________________________________
Most DOS, Windows, and OS/2 programs run under OS/2 2.0 without any
modification. A few need specific attention, such as changes to DOS
settings, for optimum performance.
GENERAL CONSIDERATIONS
______________________
Some categories of programs do not work correctly with OS/2 2.0 because of
their design, or because they use undocumented interfaces, or because they
perform restricted activities. The following list identifies these
categories of programs:
o DOS extenders that require exclusive access to the 80386 control
registers, such as the Virtual Control Program Interface (VCPI), are not
supported because they would violate the integrity of the system. The
DOS Protect-Mode Interface (DPMI 0.9), the Expanded Memory Specification
(EMS), and the Extended Memory Specification (XMS) are supported.
o Programs that directly address the physical disk sectors to perform
disk-write operations are not supported. These operations would violate
the integrity of the system. This category includes most DOS UNDELETE
programs.
o Some Windows programs make use of the Windows accessory programs, like
the Calculator. If you already had Windows Version 3.0 installed and you
did not format your hard disk when you installed OS/2 2.0, the accessory
programs are on your hard disk and are supported by OS/2 2.0. However,
the accessory programs are not part of the WIN-OS/2 environment included
with OS/2 2.0.
o Programs (and hardware) that require the Windows Enhanced mode are not
supported. This mode uses an unsupported memory-management method.
Programs that run in the Windows Standard mode and Real mode are
supported.
o Programs that manipulate the 80386 control registers, such as 386 DOS
debuggers, are not supported; this would violate system integrity.
o Fax boards and programs that use more that 1000 interrupts per second
(9600 baud or greater) are not supported. The following fax boards and
programs contain timing sensitivities that might prevent reliable
operation:
- ATI ETC
- Cardinal FAX
- Practical Peripherals
- Smartfax
- Twincomm 24/96
(C) Copyright IBM Corp. 1992 41
o If you run a bulletin board or a DOS communications application that
keeps timing out, change the DOS settings as indicated below. If the
first settings change does not fix the problem, change the next settings,
and so forth.
1. HW_TIMER to ON
2. IDLE_SECONDS to 60, and IDLE_SENSITIVITY to 100
3. COM_HOLD to ON
4. HW_ROM_TO_RAM to ON
If the DOS settings changes do not fix the problem, set PRIORITY_DISK_IO
to NO in the CONFIG.SYS file.
o If a TRAPD occurs in old DOS applications, and the CS:EIP register value
is 150:00004912, then a protection fault has occurred in the OS/2 kernel.
Use an HPFS partition as a workaround. A fix is forthcoming from IBM.
Our testing has identified the following programs that perform one or more of
the activities described above:
o Ansel for Windows
o Bound Checker (DOS)
o Central Point Backup for Windows
o Close-Up (Windows)
o Desert Storm CD-ROM (Windows)
o Distinct Back-Up (Windows)
o DoDot 3.0 (Windows)
o Fax Concentrator (DOS)
o Magic-CV (DOS)
o Mathematica 2.0 (Windows)
o MusicPrinter Plus 4.0 (DOS)
o OmniPage Professional 1.0 (Windows)
o Oracle (DOS)
(There is an OS/2 version of this program.)
o Perceive for Windows
o Phar-Lap DOS extenders prior to Version 4.0
o Realizer 1.0 (Windows)
o Sherlock Holmes CD-ROM (DOS)
o Smartfax (DOS)
o Soft-ICE (DOS)
o Splash 1.01 (DOS)
o Turbo Debugger (DOS)
In addition to the restricted activities described previously, some general
conditions you should be aware of are in the following list:
o For more reliable DOS communications performance on slower systems, the
combined baud rate should not exceed 9600 bps for one or more concurrent
DOS applications.
o You can improve the performance of DOS communications programs by using
the 16450 or 16550 buffered communications chips.
42 OS/2 2.0 Tips and Techniques
o If you lose data using DOS communications software, set the
PRIORITY_DISK_IO setting to NO in your CONFIG.SYS file, and the
IDLE_SENSITIVITY setting to 100% in the DOS settings for the object.
o Some DOS and Windows programs run correctly only in full-screen sessions.
Any Windows program that does not use the Windows API to change the video
mode should be run in a WIN-OS/2 full-screen session.
o Some DOS and Windows programs must be installed or run in a
"Specific-DOS" session; that is, in a session that was started by booting
from an actual version of DOS.
o Some programs run in OS/2 DOS or WIN-OS/2 sessions, but require that you
install the program under DOS.
o Windows programs cannot start DOS sessions or DOS programs.
o DOS programs that use low-level file system calls cannot access HPFS
disks.
o Code-page-switching support is not available for graphics mode in DOS
sessions.
o Some DOS and Windows programs use security keys as protection against
copyright infringement. The security key is a 25-pin connector that is
connected to the parallel port of the computer on which the program is
executing. The program checks to see if the connector is attached and,
if the connector is not present, the program is assumed to be an illegal
copy. When more than one DOS session is running one of these programs, a
SYS1799 error can result. This occurs because the programs that use
these security keys do not de-allocate the parallel port if a second
session is started for a program that also requires the security key.
This error is the result of a direct I/O parallel port contention
mechanism that protects the user from possible data corruption. To
disable this mechanism press Ctrl+Alt+PrtSc while the DOS session that
first performed direct I/O to the parallel port has the keyboard focus.
o Some of your Windows Multimedia Extension programs might not work
correctly after being migrated to OS/2 2.0. Reinstall them under
WIN-OS/2.
o If the SYS0005 error "ACCESS DENIED" occurs when starting DOS programs,
follow this procedure:
1. Shut down the system.
2. Insert the Installation Diskette into drive A.
3. Restart the system.
4. When prompted, remove the Installation Diskette, insert Diskette 1,
and press Enter.
5. At the "Welcome to OS/2" screen, press Esc.
Chapter 6. Application Considerations 43
6. Remove Diskette 1, and insert Diskette 2.
7. At the command prompt, type "CHKDSK C: /F:3 " and press Enter.
8. If you receive the error "cross-linked extended attribute", repeat
the previous command until CHKDSK reports no errors.
9. After repeated attempts, if CHKDSK continues to report errors, note
the names of the files related to the errors. Copy these files to a
blank diskette and delete the files from the hard disk. Then, run
CHKDSK again.
10. When CHKDSK reports no errors, copy the files back to their original
location, and restart your system.
SPECIFIC APPLICATIONS
_____________________
The following list provides information about the compatibility of specific
programs with OS/2 2.0. This information is version specific; later versions
of the same program might operate correctly. Some program manufacturers
already have resolved incompatibility issues and have fixes available; these
are noted.
o ACTION! SAMPLER 1.0 (WINDOWS)
- The DPMI_MEMORY_LIMIT WIN-OS/2 setting must be set to 5 or greater.
o ADOBE TYPE MANAGER (WINDOWS)
- When using an IBM 4029 printer in PPDS mode with Adobe Type Manager,
some Windows programs may not function correctly. If this occurs, do
not use the printer resident fonts. To disable printer resident
fonts, bring up the control panel of the Windows Adobe Type Manager
and ensure that the selection "Use Pre-built or Resident Fonts" is
disabled.
o AFTER DARK (WINDOWS)
- To run in a WIN-OS/2 window session, change the object's settings to
hide or minimize the icon to the desktop.
- This program places a TSR (terminate and stay-resident) reference in
the AUTOEXEC.BAT file when it is installed. To run in a WIN-OS/2
window session, remove this reference from AUTOEXEC.BAT.
o ALDUS PAGEMAKER 4.0 (WINDOWS)
- The spelling checker cannot locate the dictionary.
- Deselect the public setting to use the clipboard.
- If you experience incorrect output when spooling Standard format
files to the printer, set the printing to RAW mode. To do this, take
the following actions:
1. Go to the Printer icon on the desktop.
2. Select OPEN, then SETTINGS, then QUEUE OPTIONS.
44 OS/2 2.0 Tips and Techniques
3. Ensure that PRINTER SPECIFIC FORMAT is checked.
o ALDUS PERSUASION 2.0 (WINDOWS)
- Use the parallel ports to print.
- Deselect the public setting to use the clipboard.
o ARTS & LETTERS GRAPHICS EDITOR 3.1 (WINDOWS)
- The DECIPHS utility program requires that a DOS session be started
from the Windows environment; this is not supported.
- To run in a WIN-OS/2 window, change the object's settings to minimize
to the desktop.
- The directory created by Arts & Letters is named A&L. The "&"
character is a reserved character of the command shell, CMD.EXE; it
is used for conjugated command lines. To change to the A&L directory
with the CD command you must use one of two methods of quoting the
directory name. The first method is to prefix the "&" in A&L with a
¬ (caret, shift 6):
CD A¬&L
The second method is to surround the entire directory name with
quotation marks ("):
CD "A&L"
- If you are running Arts & Letters and you get a system error (a GDI
trap), you must restart the operating system before running the
program again. This is because the program left a portion of itself
running when it ended and will not start a new copy of itself while
that portion is running. This also means that when you restart the
computer, Arts & Letters will start again automatically. It is
recommended that you close the copy that is launched on system
startup and start the program from its icon when you intend to run it
in a window.
o AUTOCAD VERSION 10 (DOS)
- Close the program from the desktop.
- If a TRAPD occurs, and the CS:EIP register value is 150:00004912,
then a protection fault has occurred in the OS/2 kernel. Use an HPFS
partition as a workaround. A fix is forthcoming from IBM.
o AUTOCAD (OS/2)
- Some of the background colors are set to an unusually pale color that
does not show up well on XGA displays.
o AUTOMANAGER 4.0 (DOS)
- The version of the program that uses extended memory uses an
unsupported DOS memory extender. Use the real-mode version.
- The program expects COMMAND.COM to be in the root directory of drive
C:\. Copy COMMAND.COM from the C:\OS2\MDOS directory to C:\.
o BORLAND C++ 2.0 AND 3.0 (DOS)
Chapter 6. Application Considerations 45
- Set the DPMI_DOS_API DOS setting to ENABLED.
o BORLAND TURBO C++ 2.0 (DOS)
- The version of the program that uses extended memory uses an
unsupported DOS memory extender. Use the standard version of the
program.
o BORLAND TURBO DEBUGGER 2.01 (DOS)
- The version of the program that uses extended memory uses an
unsupported DOS memory extender. Use the standard version of the
program.
- TD386, the 386 version of Turbo Debugger, manipulates the 80386
control registers; this is not supported.
o BORLAND TURBO DEBUGGER FOR WINDOWS (WINDOWS)
- Run the program in a WIN-OS/2 full-screen session.
- The screen is temporarily corrupted when this program is called from
Turbo C++. The screen is restored on the first repaint (a repaint
can be forced by clicking the mouse on several different windows).
o BORLAND TURBO PASCAL 6.0 (DOS)
- The version of the program that uses extended memory uses an
unsupported DOS memory extender. Use the standard version of the
program.
o CENTRAL POINT BACKUP FOR DOS 7.1 (DOS)
- Displays meaningless characters when running in a DOS window session.
Run this program only in a DOS full-screen session.
o CENTRAL POINT PC TOOLS DELUXE 7.1 (WINDOWS)
- Many of the utility programs require starting a DOS session from the
Windows environment; this is not supported. Start these programs
from a separate DOS session.
- The backup feature of this program performs in a manner similar to
Central Point Backup for Windows, which is in the list of programs
that perform restricted activities. If you experience difficulty
backing up on a diskette, back up on an alternate device, such as a
network drive or a tape drive.
o COMMANDER KEEN (DOS)
- Set the VIDEO_RETRACE_EMULATION DOS setting to OFF.
o COMMUTE (WINDOWS)
- When this program is installed under WIN-OS/2, the statement
keyboard.drv=commkbd.drv is added to the SYSTEM.INI file. Change
this statement to keyboard.drv=keyboard.drv.
46 OS/2 2.0 Tips and Techniques
o CONTROL ROOM 1.0 (DOS)
- You must run this program in a DOS full-screen session for the screen
blanking feature to work correctly.
o CORELDRAW 2.0 (OS/2)
- If you do a large amount of printing while in this program, it is
possible that you might run out of system resources. To avoid this,
you should periodically save your work and exit CorelDRAW, then
restart the program and continue your work.
o CORELDRAW 2.0 (WINDOWS)
- Install the program in a DOS session.
- Run the program in a WIN-OS/2 full-screen session.

- Install the program.
- Exit WIN-OS/2.
- Run FFIX /u.
- Run the program in a WIN-OS/2 full-screen session.
o CROSSTALK (WINDOWS)
- Run "MODE COMx BUFFER=OFF" from the command line, where x is the
communications port you are using, before you run the program.
o DBASE IV 1.1 (DOS)
- If you receive a "too many files open" error message, set the
DOS_FILES DOS setting to 30. Set the DOS_VERSION DOS setting to
DBASE.EXE,5,0,255. With Hyperdisk, set DOS_VERSION to
DBASE1.EXE,5,0,255.
- When using Hyperdisk, you might have to adjust the EMS and XMS memory
limits.
- With the multi-user version, the program must be run in a
Specific-DOS session.
o DESIGNER (OS/2)
- The MIRRORS.DLL that comes with this program must be installed in the
program directory, as opposed to the C:\OS2\DLL directory, and the
program must be started from this directory. This is because OS/2
2.0 comes with its own dynamic link library named MIRRORS.DLL.
o DRAFIX CAD VERSION 1.11 (WINDOWS)
- Run the program in a WIN-OS/2 full-screen session.
Chapter 6. Application Considerations 47
o DRAFIX CAD VERSION 3.0 (WINDOWS)
- Run the program in a WIN-OS/2 full-screen session.
o DYNACOMM ASYNCHRONOUS OS/2 (OS/2)
- The DLL's included with this product must not be in the same
directory as the executable file. Put them in a separate directory
and add that directory to the end of the LIBPATH.
o ENHANCED EDITOR (OS/2)
- The OS/2 Enhanced Editor supports up to 99 fonts. If additional
fonts are installed, unpredictable results might occur.
- In the online help for the enhanced editor, it states that you should
contact your IBM representative for detailed information on how to
program the editor. Instead, obtain this information from the IBM
bulletin boards.
o F-117A STEALTH FIGHTER 2.0 (DOS)
- Set the VIDEO_RETRACE_EMULATION DOS setting to OFF.
- If the program appears to stop at a blank screen soon after you start
it, press ESC and the program will continue. Once you are past the
opening screens, the program runs correctly.
o F19 (DOS)
- Set the HW_ROM_TO_RAM DOS setting to ON and the
VIDEO_RETRACE_EMULATION DOS setting to OFF.
o FASTBACK FOR WINDOWS (WINDOWS AND OS/2)
- Use only Version 1.01, a no-charge upgrade from Fifth Generation
Systems. To order, call 1-800-873-4384.
- In the Options pull-down menu in the program, make sure that the
Media setting is set to system default. (The other Media settings
write to DMA device drivers, which have incompatibility problems.)
o FASTBACK PLUS 2.1 AND 3.04 (DOS)
- If you experience difficulty backing up on a diskette, back up on an
alternate device, such as a network drive or a tape drive.
o FASTLYNX 1.1 (DOS)
- To use the serial port with this program, remove the
DEVICE=C:\OS2\MDOS\VCOM.SYS statement from CONFIG.SYS. The parallel
port works correctly.
- Due to its high speed, the program sometimes fails to function. If
this occurs, simply end the program; system integrity is not
compromised. To minimize the possibility of this error condition,
set the following DOS settings:
HW_TIMER = ON
48 OS/2 2.0 Tips and Techniques
IDLE_SENSITIVITY = 100
IDLE_SECONDS = 10
o FORM PUBLISHER (WINDOWS)
- Ensure that the program's printer driver is installed before running
the program.
o FORMBASE 1.2 (WINDOWS)
- The SHARE statement is automatically added to AUTOEXEC.BAT during
program installation. Use an editor to remove the SHARE command from
AUTOEXEC.BAT.
- When running this program and Lotus 1-2-3 in the same Windows
session, this program must be started first.
o FOTOMAN (WINDOWS)
- Run the program in a WIN-OS/2 full-screen session.
o FRAMEWORK III 1.1 (DOS)
- The program expects COMMAND.COM to be in the root directory of C:\.
Copy COMMAND.COM from the C:\OS2\MDOS directory to C:\.
- Disable the program's print spooler; using it might cause an error.
o HARVARD DRAW (WINDOWS)
- When installing this program under WIN-OS/2, you will receive an
error dialog box. Select OK in the dialog box and installation will
complete successfully.
o HARVARD GRAPHICS (WINDOWS)
- When installing this program under WIN-OS/2, you will receive an
error dialog box. Select OK in the dialog box and the installation
will complete successfully.

Color Selection grid. Run the program in a WIN-OS/2 full-screen
session.
o HDC FILEAPPS 1.0 (WINDOWS)
- The program uses the Windows Notepad for a README text file during
installation. Indicate that you do not wish to read the file and
installation will continue.
o HP NEW WAVE 3.0 (WINDOWS)
- Install the program under DOS. If you experience problems with
program or session termination, set UseOS2shield=0 in SYSTEM.INI (in
the \OS2\MDOS\WINOS2 directory on your start-up drive). If that does
not help, run the program in a full-screen WIN-OS/2 session.
Chapter 6. Application Considerations 49
o IBM 3363 OPTICAL DISK DRIVE*
- The software for this product must be run in a Specific-DOS session
that is started from drive A.
- You should run only a small number of other processes when using this
product.
o IBM PC LAN SUPPORT PROGRAM (DOS)
- If you close the DOS session that is running this program, you must
first reset the token-ring adapter before you restart this session.
To fix this problem, download RSTTOK.ZIP from the IBM BBS or from
IBMFILES in CompuServe.
o IBM PC/3270 V2.0* (DOS)
- First, the program must be migrated using the OS/2 Migration utility
program.
- Then, in the Session Page of the DOS settings:
- Select DOS FULL SCREEN or DOS WINDOW.

50 OS/2 2.0 Tips and Techniques
- Set the Working directory to d:\path.
o INTEL SATISFAXTION
- The installation program displays the message "You have inserted the
wrong diskette" when changing from disk one to disk two. After the
error message is displayed, press Enter and the program will continue
with installation.
- At the end of installation of the Intel SatisFAXtion you are told to
remove the diskette and press any key to reboot your machine.
Instead, shut down the operating system and restart your computer.
- If SatisFAXtion software is loaded into each DOS session, it might
cause the fax to stop if another DOS session is started. Set up one
DOS session to be used for faxing, and load the device driver and
executable files only into that DOS session. To do this, take the
following steps:
1. Edit AUTOEXEC.BAT.
2. Cut the last two lines referring to the Intel SatisFAXtion board
to the clipboard and save the file (using DOS Command File for
the file type).
3. Open a New file.
4. Paste the last two lines into the new file.
5. Save the new file as FAX.BAT, using DOS Command File as the file
type.
6. Edit CONFIG.SYS and cut the last two lines relating to the Intel
SatisFAXtion board to the clipboard (cut only the last line if
you do not have a scanner installed).
7. Save the file using Plain Text as the file type.
8. In the Command Prompts folder, select a DOS Full Screen icon,
press the CTRL key and mouse button 2 at the same time, move the
mouse pointer to an empty area in the folder, and release the
mouse button and the Ctrl key. This creates a copy of DOS Full
Screen.
9. Put the mouse pointer over your new icon and press mouse button
2.
10. Click on the arrow next to OPEN, and select SETTINGS.
11. Go to the Session page and select the DOS SETTINGS push button.
12. Go to DOS_DEVICE and press mouse button 1. Then, move the mouse
to the dialog area and press mouse button 1 (there should be a
blinking cursor now).
13. Paste the text that you cut from the CONFIG.SYS file and select
SAVE.
14. Go to the General page and replace the contents of the Title box
with FAX (or whatever other title you choose).
15. If you want to edit the new session's icon, go to the General
page and select the EDIT push button.
16. If you want to have this session start each time your system
starts, move the icon to the Start Up folder.
17. Whenever you start this session, type FAX to run the FAX.BAT file
before using the SatisFAXtion board. Use the fax board in only
one session at a time.
- If you install using this procedure and you receive error messages,
install the program under DOS.
Chapter 6. Application Considerations 51
o KING'S QUEST (DOS)
- Remove the DOS=HIGH statement, if one exists, from CONFIG.SYS or from
the DOS_DEVICE DOS setting.
o LAN SUPPORT PROGRAM DEVICE DRIVERS (DOS)
- If you opened a DOS session with the DOS LAN Support Program (LSP)
device drivers, and subsequently closed the session, you must ensure
that the token-ring adapter is reset before using the LAN from
another DOS session. To ensure that the token-ring adapter is reset,
use RESETOKN.EXE or RESETOKN.SYS. These files can be retrieved from
CompuServe by issuing GO IBMOS2 and downloading RESTKN.ZIP from
SECTION 17, IBMFILES, or they can be retrieved from the IBM National
Support Center Bulletin Board System by downloading RESTKN.ZIP.
- The IBM token-ring adapter should be used by only one session at a
time.
o LANTASTIC 4.0 (DOS)
- You might experience problems with this version of LANtastic. Use
Version 4.1 instead. For more information, contact the ARTISOFT BBS
at 602-293-0065.
o LANTASTIC 4.1 (DOS)
- Run this program in a Specific-DOS session. Set DOS_STARTUP_DRIVE
DOS setting to the location of a DOS kernel to boot from.
- If you are using Artisoft AE-2 or AE-3 adapters, set your adapters to
8-bit mode, as described in the adapter documentation.
o LAPLINK PRO
- Run "MODE COMx IDSR=OFF ODSR=OFF ORTS=OFF" from the command line,
where x is the communications port you are using, before you run the
program.
o LAPLINK III 3.0 (DOS)
- It is preferable that you use the parallel port. To use the serial
port with this program, comment out the VCOM.SYS statement from
CONFIG.SYS (by putting "REM " at the beginning of the line) and
restart the computer. To use the serial port for other purposes,
uncomment the lines in CONFIG.SYS and restart the computer.
o LINKWAY MAMMALS (DOS)
- Photomotion programs might exhibit some audio breakup and video
hesitation during periods of CD ROM access.

CHAPTER 7. PERFORMANCE
_______________________
Following are some performance considerations that you should be aware of.
For more performance guidelines, see the .Information and Planning Guide
document that can be obtained through your point of purchase or retrieved
through CompuServe.
The minimum memory requirement for OS/2 2.0 is 4MB. (This includes up to
128KB that is used on some systems for ROM to RAM remapping.)
Some systems use more than 128KB for other purposes, so less than the minimum
required memory is available. On these systems, you might need another 512KB
to 1MB to satisfy the minimum requirements. Check your system to see if it
offers a way to return the memory so that you can return to the minimum
requirement.
Users concerned with response times when using some system functions, such as
loading programs, starting sessions, and switching between sessions, can
improve performance by increasing system memory. If you are running on a
constrained system (small hard disk, 16-MHz or less processor, 4MB of
memory), an additional 2MB of memory will improve performance. In the entry
memory system (4MB), the recommended file system is the FAT file system.
SWAPPER FILE
____________
The system automatically pre-allocates the SWAPPER.DAT file based on the size
of installed memory. This is done to optimize performance and reduce disk
fragmentation. To tune the size of the swapper file, see the information
about SWAPPATH in the Command Reference.
In OS/2 2.0, the SWAPPER.DAT file is designed to shrink in size when the data
segments are no longer needed, but does not shrink as expected. This problem
has been fixed by IBM APAR PJ03686, available from CompuServe or the IBM BBS.
Ignore any CHKDSK errors that might be reported on the SWAPPER.DAT file.
These error indications are normal.
FILE SYSTEMS
____________
Many performance changes have been incorporated into OS/2 2.0 File Systems.
Both file systems read ahead (for sequential I/O), lazy write to disk, and
accept threshold parameters.
A disk cache size is preselected by the system based on installed memory,
disk size, and file systems installed. The default for the entry memory
system (4MB) is a cache size of 128KB. To tune the size of the disk cache,
see the information about DISKCACHE in the Command Reference.

DOS APPLICATIONS
________________
You can improve the performance of some DOS applications by adjusting the DOS
settings. If the application does not require extended or expanded memory,
these values can be set to zero. This will provide maximum performance.
Some DOS applications use polling techniques to poll the system for work. An
example is an application that appears to be idle at an input prompt, but is
in fact polling the keyboard looking for keystrokes. Use the IDLE
SENSITIVITY choice to detect this occurrence and put the application to sleep
when it is polling.
WINDOWS APPLICATIONS
____________________
Windows applications are generally started in one WIN-OS/2 session, unless
specifically set to run in their own WIN-OS/2 session. If you use several
applications simultaneously, you might want to increase the DPMI memory limit
before starting the first application. The first application started
determines the DPMI memory available for all subsequent Windows applications
that are used.
In low-memory configurations, you can run multiple Windows applications in
one WIN-OS/2 session. This reduces both memory and swapper-file requirements.
With a WIN-OS/2 window session, a new session is created every time you
double-click on an active object. To restore the currently active object:
o Double-click on the minimized application object, or
o Display the OS/2 Window List and double-click on the application name.
If you choose to migrate your Windows applications (at installation time or
later using MIGRATE), most Windows applications will execute in one WIN-OS/2
session. If you set up a Windows application and do not use MIGRATE, each
program executes in its own WIN-OS/2 session.
If you are running Windows applications in a single WIN-OS/2 session, the
Windows clipboard can be changed from PUBLIC to PRIVATE for increased
performance. Setting it to PRIVATE means that it can be used in the single
Windows environment only.
When a large volume of data is being sent to the clipboard in a WIN-OS/2
Window session, you might receive the message:
Data not saved, possible memory or disk space error.
This data not available in clipboard.
followed by the message:
Do you want to exit clipboard?
Selecting OK to the second message will make the clipboard private to that
WIN-OS/2 session. Data that was previously sent to the public clipboard
62 OS/2 2.0 Tips and Techniques
might have remained private. You might want to use the private clipboard for
applications seeing these messages.
When you exit from a WIN-OS/2 session, the system leaves the clipboard and
DDE loaded. If you will not be returning to a WIN-OS/2 session, close both
the clipboard and DDE. Use the PM Window List to see if they are active.
To permanently disable public DDE and clipboard interchange between Windows
applications and PM applications, and between Windows applications in
separate WIN-OS/2 sessions, edit the \OS2\MDOS\WINOS2\SYSTEM.INI file. In
the "boot■ section you will find the names of these two programs in the
SAVDMApps= line, the MAVDMApps= line, and the WOS2VDMApps= line. By removing
the names of the programs from these lines, the programs will not be
automatically started. Adding them back will cause them to be started the
next time a WIN-OS/2 session starts up.
APPLICATION USAGE
_________________
If you have an application that you always use, you can set up the
application in the Startup folder to load when the system is started.
To avoid reloading frequently used applications, minimize the application
after use and simply maximize it to use it again. You can find the
application in the Window List or the Minimized Window Viewer.
If you use several different applications, the icons (objects) can be placed
on the desktop or in a folder. The folder can be set to open when the system
is restarted.
MEMORY
______
Close opened applications when you are not going to use them again.
Close folders that you do not need. Also, move commonly used functions out
of folders and onto your desktop, and close the folders that contained the
icons.
HARD DISK SPACE
_______________
To save hard disk space, be certain to install only the functions you need.
If you have installed the productivity aids and the games, and later only
want a subset of these, delete all \OS2\APP and \OS2\APP\DLL files and use
INSTALL to selectively install the items you want. Additionally, delete
TUTORIAL.HLP in \OS2\HELP\TUTORIAL if you no longer need the tutorial.

64 OS/2 2.0 Tips and Techniques
CHAPTER 8. WINDOWS VERSION 3.0 PROGRAMS SUPPORT
________________________________________________
This chapter contains tips and techniques for running Windows applications in
WIN-OS/2 sessions (window and full-screen).
OPTIMIZING WIN-OS/2
___________________
The following are tips for using your computer more efficiently in WIN-OS/2
sessions:
o Current information for WIN-OS/2 window sessions in high-resolution video
modes is available from CompuServe, the IBM National Support Center
Bulletin Board System, the OS/2 Bulletin Board System, and IBMLINK.
o If you are running Windows programs in WIN-OS/2 window sessions, you
cannot have any statement in the AUTOEXEC.BAT file that prompts the user
for input (for example, "Press any key to continue").
o Do not use the SETUP.EXE file shipped with Windows 3.0. Instead, use the
SETUP.EXE file shipped with WIN-OS/2 to ensure your environment is
properly configured for OS/2 2.0. Use the Selective Install program in
OS/2 2.0 to change video device drivers for VGA, 8514, XGA, EGA, and CGA,
and for mouse device drivers. To start Selective Install, double-click
the icon for OS/2 System, then System Setup, then Selective Install.
o To decompress Windows device drivers supplied by equipment manufacturers,
use the EXPAND.EXE utility program for WIN-OS/2 located on OS/2 2.0
Diskette 9.
o Windows Version 3.1 is not compatible with OS/2 2.0, so you cannot run it
in a WIN-OS/2 session. You can, however, run Windows 3.1 in a separate
partition. Install Boot Manager, and partition your hard disk so that
Windows 3.1 is in a partition separate from OS/2 2.0. Or, if you have
DOS and Windows 3.1 already installed before you begin OS/2 2.0
installation, consider installing OS/2 2.0 Dual Boot. With Dual Boot,
you can shut down OS/2 2.0 and start up DOS/Windows to run programs that
require Windows 3.1.
o If a Windows application does not work correctly in a WIN-OS/2 session,
it is likely that the application files were not all migrated properly.
To fix the problem, you can reinstall the application using a WIN-OS/2
full-screen session. (Select RUN on the FILE menu of the Program Manager
and use the command line there.) Or, if you know the specific files that
are needed, you can copy them from the \WINDOWS directory to the
\OS2\MDOS\WINOS2 directory.
o If you are running a WIN-OS/2 full-screen session and you have an 8514
display, use DOS Settings to set VIDEO_8514A_XGA_IOTRAP to OFF and
VIDEO_SWITCH_NOTIFICATION to ON.
(C) Copyright IBM Corp. 1992 65
o If the VIDEO_SWITCH_NOTIFICATION setting is ON, wait until you see your
WIN-OS/2 desktop in a full-screen session before switching back to the
OS/2 desktop. If the session does not start successfully, close it, and
then restart it.
o The value for VIDEO_SWITCH_NOTIFICATION should not be changed for an
active WIN-OS/2 session.
o You cannot use the WIN-OS/2 Control Panel to change mouse buttons in
WIN-OS/2 window sessions. Change mouse button settings from the OS/2
desktop to affect the WIN-OS/2 mouse buttons in the WIN-OS/2 window
environment. The WIN-OS/2 Control Panel can still be used for changing
mouse buttons in WIN-OS/2 full-screen sessions.
o If you install the US English version of OS/2 2.0, and you want to change
the system configuration to another country or language, run Selective
Install to make the changes effective for OS/2. To make the changes
effective for WIN-OS/2, start WIN-OS/2 in a full-screen session, open the
Control Panel, and use the INTERNATIONAL choice to make your changes.
o If you start an application in a WIN-OS/2 session and receive the message
"FATAL ERROR 0X0401", a problem occurred during migration of your Windows
programs so that device statements in the SYSTEM.INI file were not
updated from your \WINDOWS directory. Ensure that all device statements
are correct in \OS2\MDOS\WINOS2\SYSTEM.INI.
o If you are running a WIN-OS/2 full-screen session with an XGA video
device driver and your WIN-OS/2 icons are not clear, use the Control
Panel to choose another color scheme for the WIN-OS/2 desktop.
o To improve performance, it is preferable to have only one server or
client in a WIN-OS/2 session.
o If you have an XGA or 8514 display, keep the DDE server as an icon
instead of opening it. Also, set the DOS setting
VIDEO_SWITCH_NOTIFICATION to ON.
USING CLIPBOARD AND DYNAMIC DATA EXCHANGE
_________________________________________
o If you use the Clipboard Viewer to cut, copy, or paste from a DOS or OS/2
application to a Windows application, ensure that both the DOS or OS/2
application and the Windows application are running before marking the
text; otherwise, the copy might not be successful.
o The availability of Clipboard and Dynamic Data Exchange (DDE) functions
can vary, depending upon the types of sessions you are running.
- In standard-mode full-screen WIN-OS/2 sessions, Clipboard and Dynamic
Data Exchange (DDE) default to Public.
- In real-mode full-screen WIN-OS/2 sessions, the default is Private.
- In WIN-OS/2 window sessions, Clipboard and DDE can only be Public.
66 OS/2 2.0 Tips and Techniques
o To disable Clipboard and DDE in an OS/2 session, do the following:
1. Create a WIN-OS/2 window or full-screen session, so that Clipboard
and Data Update are started. (Clipboard and Data Update are
automatically started when you start a WIN-OS/2 session.)
2. On the OS/2 desktop, display the Window List.
3. Select Clipboard and Data Update.
4. Display a pop-up menu by clicking mouse button 2 on Clipboard or Data
Update.
5. Select CLOSE.
o To share data between WIN-OS/2 sessions only, close Data Update and
Clipboard in the OS/2 sessions.
o In a WIN-OS/2 window session, the Clipboard and DDE icons are not
available. You do not have access to the clipboard features.
However, if you want to use a private clipboard in WIN-OS/2 window
sessions, you can remove !CLIPWOS2 from the SYSTEM.INI file (in the
\OS2\MDOS\WINOS2 directory). The statements involved are those that
begin with:
SAVDMApps=
MAVDMApps=
WOS2VDMapps=
All three occurrences of !CLIPWOS2 must be removed. It is advisable to
back up the SYSTEM.INI file before making the changes, so that you can
easily restore the original SYSTEM.INI if you decide to do so in the
future.
WARNING: IF THE SYSTEM.INI FILE IS CHANGED INCORRECTLY, YOU MIGHT NOT BE
ABLE TO USE WIN-OS/2. IF YOU ARE NOT FAMILIAR WITH WINDOWS .INI FILES,
YOU MIGHT WANT TO ARRANGE FOR A PERSON WHO HAS WINDOWS TECHNICAL
EXPERTISE TO MAKE ANY CHANGES IN THE SYSTEM.INI FILE.
o To disable Clipboard and DDE in a full-screen WIN-OS/2 session, do the
following:
1. Start WIN-OS/2.
2. Click mouse button 1 on the Clipboard icon to display the window
menu.
3. Click on CLOSE.
4. Respond to the confirmation message.
5. Repeat the previous steps to close the DDE Interchange Agent.
o If you experience slow performance when using a Windows application to
copy data to the clipboard, consider the following information on
improving performance.
Chapter 8. Windows Version 3.0 Programs Support 67
The clipboard uses delayed rendering, which means only the format name is
given to the clipboard. The actual data is rendered only when the PASTE
menu choice is selected. Many Windows applications use this scheme when
they copy data to the clipboard. However, to share data between WIN-OS/2
and OS/2 sessions, the WIN-OS/2 clipboard receives all data from the
application that copied the data to the clipboard, and then sends the
data to other sessions. This process is time-consuming. You can decide
whether or not you want to share data between WIN-OS/2 sessions.
If you do not want to share data, open the Clipboard icon in a WIN-OS/2
full-screen session and turn off the PUBLIC CLIPBOARD choice on the
OPTIONS menu bar choice; however, if you want to share some of the data
between sessions, use the FILE EXPORT and IMPORT menu bar choices.
o If you are unable to paste data from the OS/2 clipboard to a WIN-OS/2
session, you need to open the WIN-OS/2 session before you copy data from
the OS/2 clipboard. The WIN-OS/2 session starts the OS/2 clipboard,
which will send the data to the WIN-OS/2 clipboard. This problem will be
fixed in a future release.
o If you cannot paste an icon from the OS/2 clipboard to a WIN-OS/2
session, the icon file might be too large, or the application might not
understand the device-independent bit map (DIB) format of the file. For
example, icons created using the Icon Editor are not understood by some
Windows applications, such as Microsoft Paintbrush. If your WIN-OS/2
session is started first, you can view the icon in the OS/2 clipboard;
however, you cannot paste it. The PASTE menu choice is grayed
(unavailable).
o If you are running several applications concurrently (each doing Copy and
Paste), you might receive from the clipboard pasted data that was
supposed to go into another application. Suppose you copy data to the
clipboard using Application 1, but do not paste it into its destination
right away. While Application 1 is doing other work, you copy data from
Application 2 to the clipboard, and you do not paste that data either.
Later, you attempt to paste the Application 1 data from the clipboard.
However, the only data that is pasted is from Application 2, not
Application 1. This happens because the clipboard can hold data from
only one cut or copy at a time. In this example, the copied data from
Application 2 replaced the data from Application 1.
To avoid having this problem, always paste the cut or copied data into
its destination application before you cut or copy data from another
application to the clipboard.
o Vertical scrolling in the OS/2 clipboard does not work. It will be fixed
in a future release. In the meantime, you can use Page Down and Page Up.
o When an application copies several sources of data to a public clipboard
in different formats, and if one of the sources creates a rendering
problem, no data is sent to other WIN-OS/2 sessions. In a future
release, only the problem data will not be sent to the public clipboard.
68 OS/2 2.0 Tips and Techniques
o When a metafile is copied to the OS/2 clipboard, it is converted into a
bit map, and then the image is enlarged. Only the center of the image is
in the clipboard window. This will be fixed in future release.
o Metafiles in WIN-OS/2 and OS/2 are not compatible. If you copy a
WIN-OS/2 metafile without bit map information to a public clipboard, it
is converted to a device-independent bit map (DIB) so that it can be
exchanged with an OS/2 session.
o If you want to use dynamic data exchange (DDE) using the PASTE LINK
choice on the FILE menu of an application, consider the following
information.
The clipboard should be set to Public. The client and server must
"negotiate" the data format to initiate the DDE link. If this
negotiation fails, some applications do not display any error message and
no further action is taken. If this happens, try another menu choice
(for example, LINK), if available.

CHAPTER 9. VIDEO/GRAPHIC SUPPORT
_________________________________
OS/2 2.0 fully supports EGA and VGA. Because of the highly graphical user
interface provided by the Workplace Shell, use of OS/2 2.0 in CGA mode will
be difficult and is not recommended. Applications designed for CGA mode are
supported and can be run even when OS/2 2.0 is running in EGA, VGA, or SVGA
mode. Resolutions above VGA (640x480x16 colors) are referred to as Super VGA
(SVGA). However, the implementation of SVGA varies widely and requires
different device drivers for different resolutions, as well as different
adapters and systems. The OS/2 Installation program will correctly configure
OS/2 2.0 and WIN-OS/2 drivers for 8514 and XGA. All SVGA adapters are
supported in VGA mode with the VGA driver provided with OS/2 2.0.
SVGA
____
The base video system and virtual display device driver in OS/2 2.0 have been
enabled for some of the most popular SVGA chips and boards. This support is
required to switch between PM and DOS or WIN-OS/2 applications. Because of
the many implementations and video modes, a limited number of video boards
have been tested.
The following Super VGA boards have been tested and found to work with OS/2
2.0 for DOS applications that make use of SVGA modes:
o Orchid ProDesigner IIs by Orchid Technology (ISA and MCA versions)
o Trident TVGA by Trident Microsystems, Inc. (8900b and c levels)
o STB PowerGraph VGA by STB Systems, Inc.
o Video Seven VRAM II, by Video Seven
o Boca Super VGA by Boca Research Inc.
o VGA Wonder XL Series by ATI Technologies, Inc.
o Paradise VGA Professional by Western Digital Imaging
VGA support is designed to be generic for the Trident, Tseng, ATI, Headland,
and Western Digital chipsets. It is likely that there are many more adapters
which are supported that have not been tested.
The 8514 Ultra by ATI must be installed as an 8514 and as a primary display;
it will default to high-resolution mode. You should update the following
statement in your CONFIG.SYS file:
DEVICE=\OS2\MDOS\VVGA.SYS
to
DEVICE=\OS2\MDOS\VSVGA.SYS
Contact the manufacturer of your computer or SVGA video adapter to obtain
device drivers and installation instructions if you want to run Windows or
OS/2 applications in SVGA modes. Information about SVGA support will be
(C) Copyright IBM Corp. 1992 71
available on CompuServe, the National Support Center Bulletin Board System,
the OS/2 Bulletin Board System, as well as many video-board and system
manufacturers' bulletin boards.
We recommend you do NOT run the video-adapter test utility programs in OS/2
2.0 unless the manufacturer has explicitly verified that they run in OS/2
2.0.
Some video adapters require that the computer's DOS BIOS initialize the video
adapter correctly. If you have one of these adapters, screen text might
appear distorted in an OS/2 full-screen command prompt. To remedy this,
start a DOS full-screen session, type EXIT, and then switch back to the OS/2
full-screen session; the text should appear normal.
To automate this process, you can create a DOS batch file to run when you
start your computer. Add the following statement to STARTUP.CMD:
START /FS /DOS DOSFS.BAT
Create the file, DOSFS.BAT, and place the following statement in it:
EXIT
SVGA ON UTILITY PROGRAM
If you have one of the video adapters listed on the previous page and want to
run DOS or Windows applications that make use of SVGA, you must turn on OS/2
2.0 SVGA support. The OS/2 Installation program detects the type of video
chip in the system; it cannot detect the type of adapter or system board that
the video chip has been implemented on. You must determine that you have a
supported configuration, and then explicitly enable SVGA.
To enable SVGA, type the following at a DOS full-screen command prompt:
SVGA ON
Then restart the system.
OS/2 SVGA VIDEO FILES
o \OS2\SVGADATA.PMI
This file indicates that SVGA support has been enabled with SVGA ON. The
file contains data on the following:
- The video chipset of your SVGA adapter.
- The SVGA modes, from the supported list, your adapter is capable of
setting. The list of supported modes is:
- 640x480/256 colors
- 800x600/16 colors
- 800x600/256 colors
- 1024x768/16 colors
72 OS/2 2.0 Tips and Techniques
- 1024x768/256 colors
- 132x25 text
- 132x43 or 44 text
- The values in the video registers when the adapter is in each mode.
This data is used by the OS/2 operating system to save and restore
the registers to their proper state when switching between sessions
with different SVGA modes set. This data file must be generated by
typing SVGA ON at a DOS full-screen command prompt, because SVGA ON
sets all the possible modes using the BIOS of the video adapter and
then reads out the values of the registers into the .PMI file. If
SVGA ON is run from a DOS window, the video virtualization of the
operating system takes over, and the BIOS does not set the SVGA modes
properly.
Even though two systems have the same video adapter, the same
SVGADATA.PMI file does not work in both. The SVGADATA.PMI file has to be
specific to each adapter/display setup.
o \OS2\SVGA.EXE
This is the utility program that generates the .PMI file and places it in
the \OS2 subdirectory. The syntax is:
SVGA ON|OFF|STATUS
where ON creates the \OS2\SVGADATA.PMI file and enables SVGA support, OFF
deletes the .PMI file, and STATUS returns the chipset type that your
adapter appears to be to the operating system.
o \OS2\DLL\DISPLAY.DLL
This file determines what video resolution the desktop uses. This is the
PM display driver. The equivalent file on a Windows system is the
VGA.DRV (in the case of VGA) file. For the first release, SVGA systems
will have a VGA display driver installed on their system. Already, SVGA
drivers are available from most of the main board manufacturers.
o \OS2\DLL\BVHSVGA.DLL
This file is the Base Video Handler for the OS/2 operating system. Any
OS/2 application that sets a video mode calls this DLL. In most cases,
however, the only application that sets any video modes is the PM display
driver and the MODE.EXE utility program (for setting 132-column modes).
The first time this DLL would be called is after the OS/2 bit-map logo
appears (PM starts up then). This DLL is specified in the CONFIG.SYS
file as the following:
SET VIO_VGA=DEVICE(BVHVGA,BVHSVGA)
BVHVGA is used to set, save, and restore VGA modes; BVHSVGA is used for
SVGA modes.
o \OS2\MDOS\VSVGA.SYS
Chapter 9. Video/Graphic Support 73
This is the virtual video device handler for DOS sessions. All calls to
change the video mode from a DOS session are handled through this driver.
The job of this driver is to allow the user to set an SVGA mode, and when
the user switches away, to save the current state of the video adapter
(its registers and its video RAM). Then, when the user returns to the
DOS session, it restores the video adapter to its previous state. When
there is no .PMI file (SVGA is OFF), this driver acts like a VGA driver,
except for adapter-specific code in it to make sure the VGA modes work
right on the SVGA adapter. Therefore, even if you do not want SVGA, you
will probably want VSVGA.
o \OS2\MDOS\WINOS2\SYSTEM\VGA.DRV \OS2\MDOS\WINOS2\SYSTEM\SWINVGA.DRV
These are the WIN-OS/2 full-screen and WIN-OS/2 window session drivers,
respectively. They determine what resolution WIN-OS/2 uses.
ADDITIONAL SVGA SUPPORT INFORMATION
o Over time, more display adapters and PC systems that offer SVGA will be
tested. Refer to the bulletin boards mentioned previously, or to the
manufacturers, for the latest support information.
o To make use of SVGA modes, you also must install Windows and Presentation
Manager video display drivers.
o If you experience display errors on an SVGA-enabled system, try disabling
SVGA support by typing SVGA OFF at a command line. This will delete the
SVGADATA.PMI file. Then restart your system.
o In some SVGA displays, if you switch to the PM desktop while the screen
is still drawing, you might experience display errors on the PM desktop.
Switch back to the SVGA screen, allowing the drawing to complete, and
then switch back to the PM desktop.
o Some screen resynchronization problems might exist in DOS or WIN-OS/2
full-screen sessions. The problem is with how some SVGA adapters handle
switching. IBM has created a new VSVGA.SYS file to correct this.
Specifically, the problem occurs most frequently with Tseng chipsets.
Video adapters using the Tseng ET4000 chipset with batch #TC6059AF have
been identified to have this problem. The VSVGA.SYS file dated 4/8/92 or
later should solve this problem.
o In the event of a TRAP000E when opening a DOS or WIN-OS/2 session on
systems with 4MB of memory and SVGA adapters, you need to obtain the
VSVGA.SYS driver replacement from IBM.
o In the event of a SYS3176 message when starting a DOS or WIN-OS/2 command
prompt, try setting the HW_ROM_TO_RAM setting in the session to ON or
changing the DOS_RMSIZE parameter in the session to 624 from the default
640. If this does not work, the VSVGA.SYS fix from IBM might resolve the
problem.
74 OS/2 2.0 Tips and Techniques
o A virtual desktop is a PM display driver that uses all of the adapter's
video memory to store a desktop that is bigger than what is actually
displayed. You could have 1024x1024 of desktop space, with only 640x480
being displayed on the screen. You move to other portions of the desktop
by dragging the mouse to the edge of the screen, which scrolls the
desktop. Because of the way OS/2 2.0 is designed, this is an extremely
quick operation and will be very smooth even on the slowest video
adapters. The PM driver must be coded to support virtual desktops, and
Trident is currently the only chipset to support it.
o Trident supports OS/2 2.0 and has SVGA Presentation drivers available for
their SVGA boards. Trident's support number is 415-691-9211. They also
have support bulletin boards where these drivers are available. For the
West Coast, the number is 415-691-1016 and for the East Coast, the number
is 203-483-0348.
o A WIN-OS/2 window session has the ability to run Windows Version 3.0
programs on the desktop. The way it is achieved is by making a place in
the desktop that the WIN-OS/2 window session driver writes to. Special
code must be put into both the window session driver and the display
driver to support this. Trident has produced 800x600/16 WIN-OS/2 window
session drivers, and has been the only one to produce SVGA support for
WIN-OS/2 window sessions so far.
o Questions about OS/2 support for adapters based on the S3 or TI chipsets
have been asked. Adapters which are co-processed are the fastest, but
also take the longest to develop software for. No manufacturers have
announced dates yet for support of any of these adapters. The more these
manufacturers are encouraged by owners of their adapters, the faster the
support will arrive.
o In the event of some corruption when returning to a WIN-OS/2 full-screen
session, set your VIDEO_SWITCH_NOTIFICATION in the DOS Settings to ON.
o Even in VGA, games in a DOS full-screen session are not optimized. Set
your VIDEO_RETRACE_EMULATION in the DOS Settings to OFF.
o Some DOS applications in a window have color corruption. This is a
limitation of the VGA desktop. The color palette of the DOS session has
to be translated to PM, and the 640x480/16 desktop does not offer enough
colors to do a good translation. The best solution is to use a 256 color
PM driver or run the application in a DOS full-screen session.
o The graphics of some applications are corrupted when displayed in a
window. These applications are probably using a non-standard VGA mode
that the adapter can support, but that OS/2 2.0 does not.
o When you have SVGA ON, you can:
- Use 132 column modes in an OS/2 full-screen session
- Take a window with an SVGA image in it and paste to the clipboard
o To enable the Windows 3.0 SVGA drivers in WIN-OS2, update the SYSTEM.INI
file to point to a new Windows display driver, or just copy over the
Chapter 9. Video/Graphic Support 75
VGA.DRV in the \OS2\MDOS\WINOS2\SYSTEM directory. Keep in mind, however,
that a Windows session in SVGA mode will only work if you have set SVGA
ON.
o Many different SVGA boards have different interfaces and chipsets, each
with their own characteristics. Some boards perform better with SVGA
OFF.
DUAL DISPLAYS
_____________
In multiple XGA configurations, when you switch from DOS to the desktop, your
system will not save and restore the hardware registers.
If your machine has an 8514 Ultra adapter and an OS/2 2.0 supported SVGA
adapter, you will need to change the DEVICE= statement in your CONFIG.SYS
file from VVGA.SYS to VSVGA.SYS.
LAPTOP LCD OR MONOCHROME PLASMA DISPLAYS
________________________________________
To change the color schemes for OS/2 system windows and create a more
readable display image, change the Scheme Palette as follows:
1. Use your Reference Diskette or hardware Setup program to set your
hardware to VGA color, if possible.
2. Open the System folder.
3. Select SYSTEM SETUP.
4. Select SCHEME PALETTE.
5. Select the monochrome scheme in the right-hand column.
This procedure will optimize the color scheme for gray-scale usage, and also
provide a good set of colors for a VGA desktop presentation.
GRAPHICS
________
Several fonts have been enhanced in OS/2 2.0. Some existing applications use
inappropriate font metrics to scale their text. In some cases, the text
becomes clipped because it no longer fits the available space.
WIN-OS/2 WINDOW AND FULL-SCREEN SESSIONS
________________________________________
When running a WIN-OS/2 full-screen session with an 8514 adapter in high
resolution (8514.DRV) mode, do not switch to a different session while an
application is updating the screen or displaying the hourglass.
The following is a procedure for enabling WIN-OS/2 full-screen sessions to
run in high-resolution (XGA) mode while the Workplace Shell Desktop and
WIN-OS/2 window sessions run in medium-resolution (VGA) mode. The procedure
assumes you are not familiar with the SYSTEM.INI and WIN.INI files.
76 OS/2 2.0 Tips and Techniques
Follow the instructions very carefully. Otherwise, you could cause your
WIN-OS/2 sessions, both window and full-screen, to become inoperable.
1. Install OS/2 2.0 for medium resolution VGA.
The next step requires that you make backup copies of your SYSTEM.INI and
WIN.INI files. DO NOT SKIP THIS STEP. It is assumed that you have a
diskette or tape backup copy of your system; instructions follow for a
backup in the directory only.
2. Back up the SYSTEM.INI and WIN.INI files.
Open an OS/2 Window from the Command Prompts folder in the OS/2 System
folder. At the ╒C:\■ prompt, type the following and press Enter:
CD\OS2\MDOS\WINOS2
COPY WIN.INI WIN.BAK
COPY SYSTEM.INI SYSTEM.BAK
Before making changes to the files, be sure the desired high-resolution
Windows device drivers and fonts are loaded in the system.
3. Check the \OS2\MDOS\WINOS2\SYSTEM directory for the desired
high-resolution display device driver. In this example, the XGA.DRV
device driver is used. Checking this directory reveals that this device
driver is not loaded. (The device driver might be loaded already, if the
system was installed in high-resolution mode and then Selective Install
was run to return to VGA mode.)
For XGA, the diskettes need to be searched for WINXGA and *G.FON. The
following shows the sequence of entries:
DIR A:WINXGA
DIR A:*G.FON
No XGA drivers were on this diskette, but one of the font files was.
Although the font file is not in a bundle of files, it is still in packed
format and must be unpacked.
The files are packed with their standard target directory coded into the
packed file. To copy the file to the system disk in the proper
directory, just run the Unpack utility program.
UNPACK A:SYMBOLG.FON
This procedure continues until all of the scalable fonts are unpacked.
These fonts are:
o SYMBOLG.FON
o TMSRG.FON
o COURG.FON
o HELVG.FON
Chapter 9. Video/Graphic Support 77
Eventually the WINXGA file is found by the dir a:WINXGA search. It
contains the WIN-OS/2 XGA.DRV and three XGA fonts.
UNPACK A:WINXGA
With all of the required driver and font files on the system disks, the
next step is to modify the SYSTEM.INI file.
4. Edit the SYSTEM.INI file and find the following line:
display.drv=vga.drv
5. This line specifies the device driver WIN-OS/2 is to use in full-screen
sessions. Change this line to point to the high-resolution device driver
that was unloaded in the steps above. In this example, the device driver
is XGA.DRV. The modified line should look like the following:
display.drv=xga.drv
Both SYSTEM.INI and WIN.INI have font entries that must be changed. In
SYSTEM.INI, these entries are:
fixedfor.fon=vgafix.fon
oemfonts.fon=vgaoem.fon
fonts.fon=vgasys.fon
For XGA, these entries must be changed to:
fixedfor.fon=xgafix.fon
oemfonts.fon=xgaoem.fon
fonts.fon=xgasys.fon
In WIN.INI, the entries:
Symbol 8,10,12,14,18,24 (VGA res)=SYMBOLE.FON
Helv 8,10,12,14,18,24 (VGA res)=HELVE.FON
Tms Rmn 8,10,12,14,18,24 (VGA res)=TMSRE.FON
Courier 10,12,15 (VGA res)=COURE.FON
Must be changed to:
Symbol 8,10,12,14,18,24 (XGA res)=SYMBOLG.FON
Helv 8,10,12,14,18,24 (XGA res)=HELVG.FON
Tms Rmn 8,10,12,14,18,24 (XGA res)=TMSRG.FON
Courier 10,12,15 (XGA res)=COURG.FON
When these changes have been made and the INI files saved, the system is
ready for running Windows applications in WIN-OS/2 window sessions (VGA mode)
and WIN-OS/2 full-screen sessions (high-resolution mode).
For 8514 displays, you must delete the following line from CONFIG.SYS:
DEVICE=C:\OS2\MDOS\V8514A.SYS
78 OS/2 2.0 Tips and Techniques
For 8514 displays, the files to find are:
o WIN8514 (contains 8514.DRV, 8514SYS.FON, 8514OEM.FON, and 8514FIX.FON)
o COURF.FON
o TMSRF.FON
o HELVF.FON
o SYMBOLF.FON
NOTES:
1. Windows application developers should note that their debuggers work in
full-screen sessions only. If you have a dual-display setup (8514+VGA),
install OS/2 2.0 for the 8514 as primary display with no secondary
display. This will allow your Turbo Debugger for Windows (TDW) or
CodeView for Windows (CVW) to run in a full-screen session on the VGA
display while the WIN-OS/2 session runs full screen on the 8514. For
CVW, make sure to use the /8 option. Quick C runs on the same display as
WIN-OS/2. If you use Quick C, you don't need a special video
configuration.
2. Installing OS/2 2.0 in this way will allow PM to run on the 8514, and
your full-screen debugger to run on the VGA. It also will provide a
"stereo" effect for all full-screen sessions; both the 8514 and VGA
displays will show the same picture, unless a full-screen application
takes advantage of video-specific features.

CHAPTER 10. HARDWARE CONSIDERATIONS
____________________________________
The following sections provide information about hardware device support in
OS/2 2.0.
PERSONAL COMPUTER MANUFACTURER (PCM) SYSTEMS
____________________________________________
OS/2 2.0 is supported on personal computers with an 80386 SX (or compatible)
or later microprocessor, with at least 4MB of memory and a 60MB hard disk
with 15MB to 30MB of free space.
IBM is currently testing personal computer manufacturer (PCM) systems for
compatibility with OS/2 2.0. The compatibility test verifies 18 key
functions of OS/2 2.0. Test results are based on selected model
configurations provided by the manufacturers. While testing is continuing,
current compatibility information about tested systems is available through
your dealer or Marketing Representative, as well as through the following
online services.
o Prodigy, Jump Computer Club, in Windows and OS/2 topic. (To join
Prodigy, call 1-800-Prodigy.)
o CompuServe, G IBMOS2, in Library 17, PCMTAB.TXT. (To join CompuServe,
call the appropriate phone numbers for your area, or Membership Service
at 1-800-848-8199, and ask for representative 239.)
o IBM National Support Center Bulletin Board System (NSC BBS). This
service is available 24 hours a day, on a toll-call basis, with no access
charge, to anyone in the world who has a modem,
asynchronous-communication software, and a switched telephone line. (The
modem should be set for 8 data bits, 1 stop bit, no parity, and the
standard transmission speed from 1200 to 9600 baud.)
To access the NSC BBS, call (404) 835-6600.

SCSI DEVICES
____________
o ProComm+ SCSI disk adapters (Micro Channel) are not supported by OS/2
2.0. You should contact the manufacturer for any details on OS/2
support.
o Some SCSI adapters have jumper pins which can be set to either
synchronous or asynchronous mode. There have been noted problems such as
no icons appearing or slow hard disk performance. This can be attributed
to the SCSI adapter and hard disk not being set to the same synchronous
or asynchronous settings. Either way, they must match. Be sure these
are set properly.
o The early versions of the IBM 16-bit SCSI adapters may experience
problems and report, erroneously, that the device is not functioning.
This can be corrected by replacing the SCSI adapter with an adapter with
updated microcode.
o Adaptec SCSI adapters do not currently support drives larger than 1GB.
ADAPTEC AND FUTURE DOMAIN SCSI DEVICE DRIVERS
Device support for the following Adaptec and Future Domain SCSI adapters is
shipped with OS/2 2.0. When any of the following adapters is installed in a
workstation, its presence is normally detected automatically, and the
appropriate device support is subsequently installed.
For reference, the names of the device drivers that support each adapter are
provided in the following table:
+-------------------------------------+-------------------------------------+
| SCSI ADAPTER OR INTERFACE | DEVICE DRIVER |
+-------------------------------------+-------------------------------------+
| Adaptec A/C 6260 | AHA152X.ADD |
+-------------------------------------+-------------------------------------+
| Adaptec AHA 1510 | AHA152X.ADD |
+-------------------------------------+-------------------------------------+
| Adaptec AHA 1520/1522 | AHA152X.ADD |
+-------------------------------------+-------------------------------------+
| Adaptec AHA 1540/1542 | AHA154X.ADD |
+-------------------------------------+-------------------------------------+
| Adaptec AHA 1640 | AHA164X.ADD |

82 OS/2 2.0 Tips and Techniques
+-------------------------------------+-------------------------------------+
| SCSI ADAPTER OR INTERFACE | DEVICE DRIVER |
+-------------------------------------+-------------------------------------+
| Future Domain MCS-600/700 | FD16-700.ADD |
+-------------------------------------+-------------------------------------+
| Future Domain TMC-850IBM | FD850IBM.ADD |
+-------------------------------------+-------------------------------------+
The TMC-850/860/875/885 and TMC-850IBM adapters will not be detected when the
adapter's BIOS is disabled. You can manually install this support in your
system by following the steps below.
NOTE: xxxxxxxx.ADD should be replaced with the file name of the
device-driver file you want to install.
1. Locate Installation Diskette 8, which contains the file, DASDDRVS.
2. Insert the diskette in drive A.
3. Change the current directory to the root directory of the startup drive.
4. Type: UNPACK A:DASDDRVS \OS2 /N:XXXXXXXX.ADD
5. Add the following line to the CONFIG.SYS file:
BASEDEV=xxxxxxxx.ADD
6. Restart the system.
OS2SCSI.SYS DEVICE DRIVER
Older versions of the OS/2 operating system used the device driver SCSI.SYS.
This has been replaced by OS2SCSI.SYS. OS2SCSI.SYS is provided in the \OS2
directory of the startup partition. Old CONFIG.SYS entries of the form
"DEVICE=SCSI.SYS" should be replaced by the entry "BASEDEV=OS2SCSI.SYS."
Normally, this is done automatically but inspect your CONFIG.SYS file if you
suspect SCSI problems.
The OS2SCSI.SYS device driver is required for a number of SCSI CD-ROM
devices, SCSI Read/Write Optical devices, and SCSI Tape devices.
SCSI CD-ROM SUPPORT
The SCSI CD-ROM support built into OS/2 2.0 has some manufacturer-specific
dependencies at this time. Support has been verified for IBM and Toshiba
SCSI CD-ROM drives. If your CD-ROM is either SCSI with no other devices
attached or is non-SCSI, you might get it to work by using an external DOS
session (VMBOOT by using the DOS Program setting, DOS_STARTUP_DRIVE ).
Information about the support and verification of additional manufacturers'
drives will be made available at a later date.
Chapter 10. Hardware Considerations 83
SCSI REMOVABLE MEDIA SUPPORT
Full-function support is not yet available for SCSI hard disk drives that
support removable media. Examples of this class of device include the
Bernoulli drives manufactured by IOMEGA, and the removable-media drives
manufactured by SyQuest Technology.
Although OS/2 2.0 recognizes these drives, it will treat media as large
diskettes. You will be able to format for the FAT file system only. You
will not be able to partition or start up from the media, and partitioned
media will not be recognized.
If the IBMINT13.I13 driver is used to control these units, the drive will be
treated as a hard disk. In this case, the cartridge must be in the drive at
startup time, and you will need to use the Shutdown procedure to remove the
cartridge from the drive.
Bernoulli 44MB and 89MB drives work if connected to Adaptec, Future Domain,
IBM, or any adapter other than the Bernoulli adapter. The drive will work as
a large diskette but cannot be used as a startup drive. Customers should
call IOMEGA for status on an update for their adapter.
If Seagate SCSI controller model ST-01 or ST-02 is present, it must be the
only disk controller present. Conflicts exist between this controller and
MFM and RLL disk controllers.
If you experience some problems with a Western Digital WD7000 SCSI adapter,
contact Future Domain for assistance.
SCSI USAGE NOTES
Following are a number of notes about usage, and about potential
compatibility problems with the microcode levels on various adapters and
devices.
ADAPTER: All Adaptec adapters
NOTE:
(1) Might produce contention problems with the
diskette drive controller on fast computers.
(2) Do not support drives of 1GB or larger.
(3) Must have SCSI hard disks configured as
SCSI target ID 0 or 1 to be able to
start up from that hard disk.
ADAPTER: Adaptec AHA-154x
DRIVE: IBM 0661 - 320MB SCSI
NOTE: Adapter BIOS will not recognize the drive as Target 0 or 1
(Drives 80, 81). For OS/2 2.0, the drive can be used but not
as a startup drive.
84 OS/2 2.0 Tips and Techniques
ADAPTER: Adaptec AHA-174x
DRIVE: IBM WDS-3180 - 80MB SCSI, IBM WDS-3160 -160MB SCSI
NOTE: Adapter will not recognize these drives when configured in
standard mode (AHA-154x emulation). Instead, the AHA-174x
_ _
adapter should be configured in enhanced mode. This mode is
supported by the OS/2 2.0 drivers, and the problem does not
occur when the adapter is operating in enhanced mode.
ADAPTER: Future Domain TMC-850/860/875/885 w/BIOS revision level 7.0.
Future Domain TMC-1660/1670/1680 w/BIOS revision level 2.0.
SYSTEM: IBM Models 35 and 40
NOTE: When the Future Domain adapter is controlling the startup
diskette, it will produce the message, "Disk read error has
occurred" when you attempt to start the Installation Diskette.
Contact Future Domain for a free BIOS upgrade.
ADAPTER: Seagate ST-01, ST-02
NOTE: Causes contention with MFM and RLL drives. The ST-01 or ST-02
should be the only drive controller installed. This problem
is being investigated.
ADAPTER: Western Digital WD7000
NOTE: Newer adapters seem to be supported while older ones are not.
Western Digital is now owned by Future Domain. Contact Future
Domain for assistance.
AMI AND CEI SCSI ADAPTERS
AMI "Fast Disk" and AMI "Fast Disk II" SCSI adapters are incorrectly
recognized as Adaptec adapters. The CEI Cumulus C5640B SCSI Micro Channel
adapter has the same problem. If you have one of these adapters in your
system, do the following:
o At the final restart after the installation is completed, delete from the
CONFIG.SYS file any line with "BASEDEV=AHA1xxx.ADD" (where x can be any
character).
o Ensure the line, "BASEDEV=IBMINT13.I13," appears in the CONFIG.SYS file.
This line should have been placed there by system installation.
Chapter 10. Hardware Considerations 85
ALWAYS TECHNOLOGY SCSI
If you are experiencing OS/2 problems either at installation time or after,
(such as a TRAP 000D) and your system has an Always Technology IN-2000 SCSI
adapter, the BIOS on the adapter might be the problem. If the BIOS revision
level is 3.06A or 3.20 (as shown during the system self-test), you should get
the BIOS on the adapter upgraded. The current BIOS level is VCN:1-02 and
works with OS/2 2.0. If you require this upgrade, you might also need an
upgrade to a companion 8-pin serial PROM chip which must have a revision
level of 2.5-2.7. Always Technology support can be reached at 818-597-9595.
ADDITIONAL DEVICE SUPPORT INFORMATION
_____________________________________
The following contains useful information about OS/2 2.0 support for the
specified devices.
HP SCANJET
If you get an error saying that you cannot access your HP scanner, and you
are using an ISA (AT-style) bus machine, your adapter switches need to be set
to 1010.
If you are using a PS/2 computer, you must use the Reference Diskette to set
the adapter to ROM addresses C8000-CBFFF and I/O address to 268-26F. In both
cases, you also need to set the DOS Setting for the DOS session for

TAPE DRIVES (ADAPTER OR SCSI)
The only tape drives that have been tested at this point are IBM tape drives.
If no other device is connected to the SCSI bus on its adapter or the tape
adapter, then you might be able to get your drive to work in an external DOS
(VMBOOT) session.
If the tape drive worked under OS/2 version 1.x and the device is written to
ASPI, IBM is currently working on support for your device. IBM does not
provide third-party device drivers for peripherals. Refer to your peripheral
manufacturer for OS/2-specific support.
TAPE DRIVES (DISKETTE BASED)
IBM or IRWIN tape drives are supported. Applications are PMTAPE or PS2TAPE.
Easy Tape from Maynard Backup Systems is scheduled for future release.
Contact Maynard for information.
86 OS/2 2.0 Tips and Techniques
TAPE DRIVES (COLORADO JUMBO)
For Colorado Jumbo tape drives connected to a floppy controller, you must
setup a DOS Startup session from a diskette image and run the tape backup
program from it. To do this, you need to refer to the topic "Starting DOS
from an image file" in the Master Help Index.
The Colorado Jumbo Tape program allows you to specify some hardware and
software settings to be used when backing up files. The CONCURRENT DISK/TAPE
OPERATION option must be set to No. To change the option, start the program
and select the Utilities menu (F3); then select SOFTWARE SETUPS (F6). Change
the option to N.
IBM PS/2 MODEL 30-286 UPGRADES
IBM PS/2 Model 30-286 upgrades to a 386 microprocessor are not supported.
50 MHZ SYSTEMS
There have been some intermittent problems using 50 MHz systems with AT-style
bus computers with a mouse. The mouse can get out of synchronization. Input
will function through the keyboard and the mouse, but to avoid possible
problems, shutdown the system and restart to resynchronize the mouse.
LOGITECH 3-BUTTON MOUSE
The Logitech 3-button bus mouse is supported as a 2-button mouse. It is
treated as a Microsoft 2-button bus mouse.
A Logitech serial mouse with 3 buttons behaves as expected in DOS sessions.
In a Presentation Manager session, however, there might be different and more
limited functions assigned to the buttons. There are no standards for the
functions of 3-button mice.
AOX SYSTEMS
If your computer has an Aox add-in processor card and you encounter problems
either installing or starting up your OS/2 system, you can call Aox support
and ask for the latest "flash-prom" code upgrade.
ORCHID VIDEO ADAPTERS
Orchid is working on OS/2 drivers for their video adapters. For more
information, you can reach Orchid's bulletin board service at:
o 510-683-0327 for 2400 baud, parameters n,8,1
o 510-683-0555 for 9600 baud, parameters n,8,1
Chapter 10. Hardware Considerations 87
ISA (NON-MICRO CHANNEL OR NON-EISA) BUS SYSTEMS
Some customers with AT-bus (ISA) systems might have disk controllers that are
not recognized or supported by OS/2 2.0. OEM drivers for their disk
controller might not yet be available. Symptoms include:
o Very slow installation
o Very noisy hard disk during installation
o FDISK errors
o Disk not recognized
IBM has a new IBM1S506.ADD disk driver available that will fix many of these
problems. It can be obtained from any of the sources described in Chapter 2
"Service and Support Information." In the event you cannot get this new file,
or if the new file does not solve your particular problem, you might do the
following:
1. Use DOS to edit the CONFIG.SYS file on Diskette 1 in the 2.0 package.
Change the line
BASEDEV=IBM1S506.ADD
to
REM BASEDEV=IBM1S506.ADD
2. Insert the Installation Diskette and proceed with the installation
through the first five diskettes.
3. After Diskettes 1 through 5 are processed, you are asked to reinsert the
Installation Diskette. DO THIS. After copying some files from the
Installation Diskette, you are asked to remove it and press Enter to
restart. DO NOT DO THIS. LEAVE THE INSTALLATION DISKETTE IN THE DRIVE.
4. Press Enter with the Installation Diskette in the drive. This will start
up the Installation Diskette. You will be asked to insert Diskette 1.
DO THIS. Watch the screens carefully. You will see a screen that tells
you (on the lower left) to press Esc to exit. When you see this, press
Esc.
5. You are now at a command line. Enter the following commands:
RENAME C:\OS2\IBM1S506.ADD IBM1S506.XXX
COPY C:\OS2\IBMINT13.I13 C:\OS2\IBM1S506.ADD
NOTE: If C is not the drive you are installing to, adjust the commands
accordingly.
6. Remove the diskette from the drive. Press Ctrl+Alt+Del to restart the
system, and the installation program will continue from where it left
off.

INTERRUPT PROBLEMS ON AN ISA SYSTEM
On an ISA system, having a shared interrupt-request line can cause problems.
ISA systems have what are called "edge triggered" interrupts whereas Micro
Channel and EISA systems use "level sensitive" interrupts. "Edge triggered"
interrupts can only be sensed for a very short period of time. If a second
interrupt arrives from another adapter while the first interrupt is still
being processed, the second interrupt will be lost. In your computer system,
this situation can lead to various difficulties such as printers that do not
seem to print smoothly or reliably, or communications sessions where some
characters are getting lost.
However, with single-tasking systems such as DOS, the two adapters that are
sharing the interrupt might never cause any real problems because they might
never be in use at the same time. OS/2 2.0, however, presents a different
set of problems. If you have multiple serial communications adapters, there
is a greater probability that you might try to use two or more of them at the
same time. If some of them have previously been set up using shared
interrupts, problems can occur that probably didn't happen in DOS.
OS/2 2.0 can detect that an interrupt line is shared and will not allow
simultaneous use. Assume that COM1 and COM3 are sharing Interrupt Request
line 4 (IRQ4). If you try to use both COM ports at the same time, the OS/2
operating system will not allow the second one to start. A well-written OS/2
communications program will recognize that the port cannot be opened and an
error message will be displayed. A DOS application, however, is unprepared
to respond to this unfamiliar situation. It will probably suspend, waiting
for the port that will not open.
Another potential source of trouble is having multiple hardware adapters that
are sharing the same I/O address. The various hardware adapters in your
computer must have their own addresses. Consider what might happen, for
example, if the commands that were meant for your printer were instead routed
to your disk drive.
The solution for all of these problems is to ensure that all your hardware
adapters have their own unique I/O addresses and IRQ assignments.
COM3 OR COM4 SUPPORT ON AN ISA SYSTEM
The original ISA machine (the IBM PC-AT) allowed for the definition of up to
four serial communication ports. However, there has never been any hardware
architectural standard that defined the I/O port addresses or Interrupt
Request (IRQ) lines associated with communication ports 3 or 4.
Over the years, a convention has developed that places the port addresses for
COM3 and COM4 at 03E8 and 02E8 respectively. This is a generally accepted
convention, but not a standard. Check the documentation and the settings of
the adapters in your system to verify your hardware environment.
After you have checked and set the I/O and IRQ values on your COM ports or
internal modems, you must add this information to the communications
device-driver (COM.SYS) statement in the CONFIG.SYS file.
Chapter 10. Hardware Considerations 89
You might also need to tell your communications application software where
the COM ports are. ProComm software, for example, has a configuration screen
that enables you to specify these settings. If the application, operating
system, and hardware are not in agreement, then the application will not run.
OS/2 COM ports do not need to be defined in sequence. It is acceptable to
have a COM4 without having a COM3. DOS, however, might have difficulty if
there is a gap in the port definition. To avoid confusion for DOS, you can
define COM ports that do not have any physical adapters attached in the
COM.SYS statement. These substitute definitions will serve as placeholders.
COM1 and COM2 are assumed to have standard values and do not need to be
explicitly set up unless you want to set some non-standard values to
accommodate your particular configuration.
To enable COM3 or COM4 on an ISA system, place the following in the
CONFIG.SYS file:
DEVICE=X:\OS2\COM.SYS (n,a,i) (n,a,i)
where
X = the drive where OS/2 is installed
n = the COM port that you are attempting to access
a = communications port I/O address (03E8, 02E8, for example)
i = IRQ level, which is usually a jumper setting on the I/O adapter
For example, to specify that COM3 is at address 03E8 on IRQ5 and that COM4 is
at address 02E8 on IRQ10, use the following statement (assuming that OS/2 is
installed on drive C):
DEVICE=C:\OS2\COM.SYS (3,03E8,5) (4,02E8,10)
The I/O address and IRQ level should be noted in the documentation that came
with your adapter. Either or both might be fixed values or can be set to a
range of values via jumpers or switches. In some cases you might find that
the values are fixed or that the range of settings available to you is
insufficient to avoid the sharing conflict. In that case, you must purchase
a different, more versatile adapter or accept that you cannot use both
adapters at the same time.
SETTING THE INTERRUPT REQUEST (IRQ) LEVEL ON AN ISA SYSTEM
The following information will help you determine what IRQ settings you can
use for COM3 or COM4 port adapters to avoid shared interrupts.
On an ISA machine there are a total of 15 IRQ levels available. Many of
these are already being used. Most are already in use because they are the
the standard settings for the more common devices. These standard settings
are as follows:
90 OS/2 2.0 Tips and Techniques
IRQ LEVEL DEVICE ASSOCIATED
0 System Timer
1 Keyboard
2 Secondary Interrupt Controller (see note)
3 COM2 (Serial Communications Port 2)
4 COM1 (Serial Communications Port 1)
5 LPT2 (Parallel Port 2)
6 Diskette
7 LPT1 (Parallel Port 1)
8 Realtime Clock
9 open
10 open
11 open
12 open
13 Math Coprocessor
14 Hard Disk
15 open
NOTE: On the IBM-AT (ISA bus), the IRQ9 pin is identical with the IRQ2 pin
on the original IBM-PC. If you have an older, 8-bit adapter whose
documentation states that it uses IRQ2, be aware that this will
actually be interpreted as IRQ9 when plugged into the 16-bit ISA bus.
The IRQ levels shown as "open" have no established, standardized use. When
setting the IRQ values on your COM3 or COM4 ports, you are likely to find
these levels available to use without conflict with some other adapter.
Furthermore, if you don't have two parallel ports installed, IRQ5 might be
usable for some other purpose, such as COM3 or COM4. Be cautious about doing
this because it might cause a problem later if you decide to install a second
parallel port. In addition, some other non-standard device might already be
using IRQ5.
When trying to manage the IRQ levels of your various hardware adapters to
avoid conflicts, you may find that your 8-bit adapters cause problems.
Except for IRQ9, only 16-bit adapters are configurable to use IRQ levels
higher than 7. A glance at the IRQ table will also show that the
low-numbered IRQ lines already have some standard function assigned. It
Chapter 10. Hardware Considerations 91
might be that your only alternative for avoiding some IRQ conflicts is to
purchase a more versatile 16-bit adapter.
If you have non-standard 8-bit adapters, be especially careful of interrupt
conflicts. For example, the SoundBlaster adapter is configured at the
factory to use IRQ7. IRQ7, however, is the standard assignment for LPT1, the
first printer port. This conflict might not be apparent with DOS because DOS
printing typically does not use the interrupt line. OS/2 2.0, however,
requires it, and the hidden conflict can become the source of printing
problems. It is also fairly common to discover that the interrupt feature on
your parallel port adapter does not work. In DOS, this might not have any
effect. In OS/2 2.0, however, your printer might be very erratic or not work
at all.
PARALLEL-PORT-ATTACHED DEVICE
o If you have a parallel device (for example, a tablet system, LAN adapter,
or SCSI device) that does not work in a DOS session, it might be because
interrupt IRQ7 is not reflected in the session. Your device might
attempt to use the parallel-port feature and is prevented from doing so.
OS/2 developers are working on a solution for this limitation.
o Some security devices (known as dongles) attached to a parallel port do
not work properly with OS/2 2.0. The DOS application that uses the
device can start from one DOS session only. An error message appears
when you try to start additional copies of the application. You can
press Ctrl+Alt+Print Screen to release access to the parallel-port
software prior to starting the second copy of the DOS application.
o Make sure you are using cables that are properly shielded and wired.
(For more information, refer to "Unable to Print" on page 35)
PROBLEMS WITH FAX ADAPTERS
When certain fax adapters are operating as ordinary modems, they might
operate correctly yet fail to work correctly as a fax device in a DOS
session. The probable cause of the trouble is the VCOM.SYS device driver.
VCOM.SYS might be introducing timing distortions into those hardware commands
that are used to control the fax device but are not a part of normal
asynchronous communications.
Because there are no standards established for fax controls, it might be that
the only solution is to acquire an OS/2-based fax device driver and
application software. Your fax adapter manufacturer might have information
on sources and availability of OS/2 based software.
Without purchasing new software, you can try removing the VCOM.SYS statement
from your CONFIG.SYS file. This might allow your fax adapter to work
properly but might have other undesirable side effects. One of the functions
of VCOM.SYS is to provide a performance assist. Without VCOM.SYS, you might
have to use a reduced baud rate. Also, some applications, such as Prodigy,
92 OS/2 2.0 Tips and Techniques
will not run without it. Therefore, while removing VCOM.SYS is OK in some
instances, it might not be the right action for you.
If you have an ISA bus system, you might consider making changes to the fax
adapter so that only part of your system detects it. Then, place all
operation into a single DOS session. This is possible on an ISA system if
you can set up your fax adapter as COM3 or COM4. Since there are no
standards for COM3 or COM4 on an ISA system, OS/2 2.0 will not recognize the
adapter unless it is defined for the system in the CONFIG.SYS file (See the
section "COM3 or COM4 Support on an ISA System" found earlier in this
chapter).
To set up this configuration, set the hardware switches on the fax adapter to
indicate either COM3 or COM4. Use a setting that is available and that does
not conflict with other adapters. Leave VCOM.SYS in your CONFIG.SYS
definition but do not define the fax adapter settings to the COM.SYS device
driver. When OS/2 2.0 starts up, it will not recognize the fax adapter, but
the normal communications ports will still get the benefit of having VCOM.SYS
available.
Next, set up a DOS session so that it loads the DOS application software that
you use for faxing and also the DOS device driver used to control the fax
adapter if it came with a special driver. Check your documentation to be
sure. This single DOS session should now be able to operate your fax adapter
normally.
In some cases, this still might not work. If the DOS application treats the
adapter as a COM port instead of directly accessing the hardware, then DOS
will not recognize the adapter either. The only problem with this
configuration is that this single DOS session controls the adapter. Other
DOS or OS/2 sessions will not be able to access it at all.
IBM is working on a fix to alleviate this problem, but the best solution will
be to use OS/2-specific device drivers and applications, especially where
performance is critical.
PS/2 EXTERNAL 5.25-INCH 1.2MB DISKETTE DRIVE
If you cannot get the external 5.25-inch 1.2MB diskette drive to work on a
PS/2 computer, install the device driver that comes with the drive into the
\OS2 directory in the startup partition. The device driver is called
EXT5DD.SYS. Change your CONFIG.SYS file statement to read \OS2\EXT5DD.SYS
instead of \OS2\EXTDSKDD.SYS.
IBM PS/2 MODEL 90 OR 95
If you are experiencing problems with your Model 90 or 95, ensure your system
is at the latest engineering change (EC) level. Your IBM service
representative can assist you.
If your Model 90 or 95 is a 33 MHz system and you are having intermittent
difficulty identifying memory parity errors such as TRAP 0002, forcing you to
Chapter 10. Hardware Considerations 93
restart your system, then ECA053 might apply. If your processor card has
part number 84F9356, contact your IBM representative to assist you with a
replacement.
If your Model 90 is experiencing intermittent memory errors, ECA084 might
apply if the part number of your memory riser card is N33F4905 or 84F9356.
Again, your IBM representative can assist you with a replacement.
For both Model 90 and 95 computers, you must ensure that you have matched
pairs of single in-line memory modules. This means that each pair of single
in-line memory modules, as described in your technical reference manual, must
be matched in memory size and speed. Mixing these modules can cause some
computers to report memory errors.
FORMATTING DISKETTES
____________________
If you have a non-Micro Channel system with a 5.25-inch drive, and its
3.5-inch drives all support media sense, your 5.25-inch drive will format
diskettes at 720MB. Previously formatted 1.2MB diskettes will read and write
correctly. A fix for this problem can be obtained from the electronic
bulletin board described in Chapter 2 "Service and Support Information."
