README
Welcome to OS/2* Warp Version 3 (OS/2 Warp).
This README contains the latest information available.
It also contains helpful hints found in our testing.
The README is only one source of information provided
with OS/2 Warp. Greater detail can be found in:
o User's Guide to OS/2 Warp
o Using OS/2, a new tutorial
o The Information Folder located on the Desktop,
which provides new online books to help you learn
and develop skills using OS/2 Warp:
- Master Help Index
- Command Reference
- REXX Information
- Multimedia
- Printing in OS/2
- Performance Considerations

- Windows Programs in OS/2
The Application Considerations online book, for
example, contains helpful hints on running games
under OS/2 Warp. The Printing in OS/2 online book
helps with installing new printers or solving
problems. These are a few of the many items
found in the new online books.
To help you locate information in this README, you
can use the Find option in the Edit menu of the OS/2
System Editor. You can print the file by dragging it
to your printer object or by using the Print choice
on the pop-up menu.

1.0 CREATING DISKETTE IMAGES FROM THE OS/2 CD
_________________________________________
To create diskette images from the OS/2 CD after OS/2
Warp has been installed, you must first find out how
many diskettes you will need. Follow these
procedures:
1. Place the OS/2 CD in the CD-ROM drive.
2. Type DIR X:\DISKIMGS\OS2\35 /W (where X: is the
CD-ROM drive) and press Enter.
3. When a list of files appears on your screen,
count the files that end with the .DSK extension.
Each .DSK file requires one formatted diskette.
Use the following command to create each diskette
image:
X:\DISKIMGS\XDFCOPY X:\DISKIMGS\OS2\35\diskname.dsk A:
where:
X: Is the drive letter of the
CD-ROM drive.
\DISKIMGS\XDFCOPY Is the location and name of
the program used to create
the diskettes.
\DISKIMGS\OS2\35 Is the location of the files
containing the diskette
images.
DISKNAME.DSK Is the diskette image file
name (for example,
DISK0.DSK).
A: Is the drive letter of your
3.5-inch diskette drive.
For example, to create the Installation Diskette
(DISK0.DSK), type the following and press Enter:
X:\DISKIMGS\XDFCOPY X:\DISKIMGS\OS2\35\DISK0.DSK A:
(where X: is the CD-ROM drive and A: is the diskette
drive.)
2.0 ENHANCED IDE HARD DRIVES GREATER THAN 528MB
___________________________________________
If you have an Enhanced IDE hard drive that has a
capacity of greater than 528MB (greater than 1024
cylinders), note the following restrictions:
The FAT file system is limited to partition sizes of
less than 1024 cylinders.
The HPFS file system can support data partitions that
are greater than 1024 cylinders. However, the partition
from which OS/2 is started cannot be greater than 1024
cylinders. The HPFS file system can support drives up
to 2GB.
3.0 MULTIPLE VERSIONS OF WINDOWS
____________________________
OS/2 Warp does not support multiple versions of
Windows (for example, Windows 3.1 on drive D and
Windows for Workgroups** 3.1 on drive E) or multiple
installations of the same Windows version (for
example, Windows 3.1 on drive D and Windows 3.1 on
drive E).
4.0 WIN32S VERSIONS 1.0 AND 1.1 APPLICATIONS
________________________________________
Install your Win32s applications in a WIN-OS/2*
Full-Screen session. You can then run your Win32s
applications in either a WIN-OS/2 Window or Full-Screen
session.
5.0 REPETITIVE SOUNDS OR NO SOUND AFTER SYSTEM
__________________________________________
INSTALLATION
____________
If your computer produces unusual or repetitive
sounds, or no sounds at all, after you have installed
OS/2 Warp, you might have a mismatch between the device
driver parameters supplied by OS/2 and the sound
adapter card or the BIOS setting of your computer.
To determine if this situation exists, use the RMVIEW
utility program to display the OS/2 device driver
types and parameters installed on your computer. The
program quickly scrolls through the device types.
The audio card is in the last section of the devices.
1. Open an OS/2 Window or Full Screen session.
2. Type the following:
RMVIEW (press Enter)
3. Note the following parameters (where X will be
replaced by a value):
I/O = 0X0XXX
IRQ Level = X
DMA Channel = X
These are the parameters that OS/2 is using for
your audio device.
4. Refer to the hardware documentation that came
with your audio card to determine the hardware
settings of your audio card. Note the following
parameters:
Port address or I/O = 0X0XXX
Interrupt level or IRQ Level = X
DMA Channel = X
5. If hardware and software settings are not the
same:
a. Select OS/2 System from the OS/2 Desktop.
b. Select System Setup.
c. Select Selective Install.
d. Select the Multimedia Device Support icon.
The Device Selections and Settings window
appears. The audio card appears in the
Devices(s) in System to be Installed window.
e. Select the Device Settings push button. A
window appears with your port address, DMA,
and Interrupt Level settings.
f. Select the values that match the hardware
settings for your audio card. Then select
OK.
g. When the Device Selections and Settings
window reappears, select OK.
h. When the System Configuration screen
reappears, select OK.
i. At the OS/2 Setup and Installation screen,
select Install.
j. When the Source Directory window appears,
select Install.
k. Follow the instructions that appear on your
screen.
6. Shut down and restart your computer so that these
changes will take effect.
If the sound problem continues, there might be a
conflict with the BIOS settings of your computer. To
determine if this condition exists, you will need:
o The hardware utility diskette for your computer
o The documentation that came with your computer
When you have the diskette and documentation, follow
these steps to determine the hardware configuration:
1. Insert the hardware utility diskette into drive
A.
2. View the BIOS settings that are configured for
your computer. Refer to your hardware
documentation for details about viewing this
information.
3. Compare the IRQ Level from the RMVIEW utility
program display with the hardware IRQ or
Interrupt Level found in the hardware
documentation. If the hardware IRQ or Interrupt
Level for the LPT port is set to enable at 5 or
7, disable it. Refer to your hardware
documentation for details about disabling and
saving the new settings.
NOTE: OS/2 Warp parallel printing no longer requires
an IRQ setting.
If you experience unusual sounds in a WIN-OS/2*
session, refer to the online help contained in the
Multimedia book located in the Information folder on
your Desktop.
6.0 DESKTOP SETTINGS NOTEBOOK
_________________________
When using the Archive page of the Desktop Settings
notebook, specify a drive that is managed by the same
file system as the drive on which your Desktop
resides. For example, if your Desktop is managed by
the FAT file system, do not specify a drive for an
Archive location that is managed by HPFS.
Use the FDISK OS/2 command to display the file system
of the drive on which your Desktop resides. The file
system is displayed in the FS Type field.
7.0 MONOCHROME MONITORS
___________________
If you are using a laptop computer (such as the IBM*
ThinkPad* 750 or 750P) with a monochrome display and
the Western Digital** display driver is installed,
you might experience problems with the way the cursor
is displayed. For example, when you use Alt+Esc to
switch from a full-screen session to the OS/2
Desktop, the cursor might appear completely black
until it is moved. In addition, changing the size of
a window with the mouse can leave a trail of
discolored pixels as the cursor moves. These
problems do not occur on an external color monitor or
when the VGA driver is installed.
8.0 LOTUS NOTES DOES NOT SUPPORT COMET CURSOR
_________________________________________
You cannot use the OS/2 Warp Comet Cursor with
Lotus Notes.
9.0 LOTUS APPROACH 3.0 NEEDS TO HAVE MEMORY SETTING
_______________________________________________
ADJUSTED
________
To use Lotus Approach 3.0, change the DOS memory
setting DPMI_MEMORY_LIMIT from 64 to 10 before you
run the application. Do the following:
1. Display the pop-up menu for the Lotus Approach
3.0 object, the WIN-OS/2 Window object, or the
WIN-OS/2 Full Screen object.
2. Select Settings.
3. Select the Session tab.
4. Select the WIN-OS/2 Settings push button.
