  Introduction



  Welcome to the IBM* OS/2* 2.0 02/92 Early Experience Program
  (EEP). This offering, level 6.304E, is available to those customers
  who wish to test new functions that have been added to the
  Limited Availability (LA) product. Not only does this version
  contain the key functions that were announced for the LA offering

  at COMDEX/Fall 1991, (including DOS and Windows** compatibility
  and the OS/2 Workplace Shell, an easy-to-use, icon-based
  graphical user interface), this version also supports:
  ■ DOS, Windows, and OS/2 applications running in windows,
  side-by-side, on a single desktop, including Windows
  applications that run in a PM* window when the primary

  display adapter is configured for VGA
  ■ A superior platform for customer networking and
  communications environments, including a graphical
  login/logout and connection to a LAN, and an ability to browse
  file server devices (such as printers and disks).

  Application developers using pre-release code at level 6.177 may
  choose to maintain their development environment on 6.177 rather
  than move to 6.304E. A development environment on 6.304E
  requires a Developer's Toolkit at level 6.304E.

  When this product becomes generally available, it is IBM's intent
  to additionally:

  ■ Provide a superior operating environment through system
  integrity, performance, interoperability, and ease of use when
  running DOS, Windows, and OS/2 applications
  ■ Run on Intel 386SX and higher systems.

  This booklet describes those product considerations about which
  you should be aware as you install and use this version of the
  product. IBM will continue to make enhancements before the
  product becomes generally available, and we welcome your
  feedback. This booklet also includes helpful tips and techniques.




  Introduction1

















1 ******************** Page: 2        ********************


  We recommend that you read this booklet before installing and
  using the system.

  This document is a supplement to OS/2 2.0 Getting Started,  OS/2
  2.0 Using the Operating System,  OS/2 2.0 Installation Guide , and
  OS/2 2.0 Quick Reference. If you are migrating from OS/2 Version
  1.3 or Windows Version 3.0, we recommend that you read  OS/2 2.0
  Migrating to the OS/2 Workplace Shell.






































  2 OS/2 2.0 02/92 EEP Product Considerations

















1 ******************** Page: 3        ********************



  Installation

  ■ If you are installing this version over an earlier OS/2 2.0 level,
  select the  Format your disk during installation  option. This
  process ensures that any earlier-level files will not be left
  inadvertently on your hard disk. Be sure to back up any files
  that you want to save before starting the OS/2 2.0 Installation

  process.
  ■ If you install this version, you will have to select the  Format
  your disk during installation  option when you install the
  product when it becomes generally available.

  ■ You do not  have to format your disk if you are installing over
  OS/2 Version 1.2, OS/2 Version 1.3, DOS, or Windows.
  ■ When first prompted to restart (reboot) your system after

  installation, note that the restart can take about 5 minutes,
  allowing the OS/2 Workplace Shell to initialize itself.
  ■ If you are installing using a response file, you cannot use the
  value for  Migrate Applications  provided in the sample response
  file. If you wish to migrate existing applications, you must
  select the Migrate Applications object located in the System
  Setup folder after OS/2 2.0 has been installed.

  ■ Be sure, if you install a mouse, that it is connected whenever
  you start your system.

  ■ This product supports two display adapters. If the secondary
  display adapter is an XGA* or 8514/A adapter, it will run in
  VGA mode.
  ■ Specific small computer systems interface (SCSI) adapter
  support for selected SCSI adapter interfaces is included. The

  device drivers which produce this support are installed in your
  \OS2 directory, as follows:
  SCSI Adapter Filename (in \OS2 Directory)

  Adaptec 152x AHA152X.ADD
  Adaptec 154x AHA154X.ADD

  Adaptec 164x AHA164X.ADD

  Future Domain TMC-8xx FD8XX.ADD
  Future Domain TMC-16xx FD16-700.ADD

  Future Domain MCS-600 FD16-700.ADD

  Future Domain MCS-700 FD16-700.ADD
  Note:  For the Future Domain TMC-8xx series, the BIOS must
  be enabled in order for these 8-bit adapters to function.

  You can manually install this support by adding a
  BASEDEV=filename statement into CONFIG.SYS. For
  example, if you have an Adaptec 1542 SCSI adapter in your
  system, you can install OS/2 support by including the
  statement BASEDEV=AHA154X.ADD at the end of your
  CONFIG.SYS file. Make sure you do not  include a drive letter
  or path in this statement.

  The CONFIG.SYS statement BASEDEV=IBMINT13.I13, included
  in the CONFIG.SYS file (by default), replaces the DSKBIOS1
  function. No special action is required to use any other SCSI
  hard files. They are supported through the IBMINT13 generic
  DASD device drivers.
























  4 OS/2 2.0 02/92 EEP Product Considerations

















1 ******************** Page: 5        ********************



  Product Considerations

  IBM will continue testing and enhancing this product before it
  becomes generally available, and we welcome your feedback.

  It is our intent to address the limitations described in this Product
  Considerations  section before this product becomes generally
  available. Where available, we have provided temporary
  work-arounds.



  Performance

  IBM strongly recommends that you do not use this version of the
  OS/2 2.0 product for performance benchmarking. We will continue
  to improve performance before the product becomes generally
  available.

  IBM's performance objectives for the OS/2 2.0 product are to run
  DOS and Windows applications equal to or better than they run in
  their native environments and to run OS/2 applications equal to or
  better than they run on OS/2 Version 1.3. Based on IBM's
  measurements of application performance on this version of the
  product, IBM believes that from a user's perspective, on balance,
  these performance objectives have been met.

  Users may experience slower response times when using some

  system functions, such as loading programs, starting sessions, and
  switching between sessions. A minimum of 6MB of system
  memory will improve performance.


  OS/2 Workplace Shell
  ■ The OS/2 2.0 product was designed for use with a mouse. We

  recommend that you operate the system with a mouse to
  ensure consistent results.
  ■ In some instances, Help is not available from the  Help  push
  button or the F1 key. Refer to the Master Help Index for help
  on specific topics.



  Product Considerations5

















1 ******************** Page: 6        ********************


  ■ Copying a folder containing program objects onto a diskette
  appears successful, but if you try to start or copy the programs
  from diskette onto another system under this version of the
  product, the program objects will not be present. (When the
  OS/2 2.0 product becomes generally available, program
  objects will not be allowed to be dropped on diskettes).

  ■ The pop-up menu for multiple-selected items does not always
  display the actions that are common to all the selected objects.
  ■ The size and position of some windows may not be restored

  after you restart your system.
  ■ Program objects started from command files must have the
  proper .BAT or .CMD extension specified.

  ■ Copying a read-only folder into another folder creates two
  folders.
  ■ Displaying an object in Details view does not always display
  current information about the object. The last access and
  modification dates may not be current. The column titles may

  be displayed for file-type objects when none are present in the
  folder.
  ■ The hard-disk icon in the Drives folder represents tape drives
  and CD-ROM drives in addition to hard disks.

  ■ The Undo option on the Associations page in the Settings
  notebooks for a Program object and the Color Palette object
  are not operational.

  ■ On systems with an XGA adapter connected, you must close
  each section of the Tutorial before moving to the next section.
  ■ The Special Needs page of the Keyboard object has limited
  customization capabilities.

  ■ Make sure you select Shut down  before you turn off your
  computer or you might lose data or the position of your icons.
  ■ The Settings notebook for ]System╪ in the System Setup folder

  has two pages with a ]window╪ tab. The page with the radio
  buttons for Animation should be used. The other page will be
  removed.




  6 OS/2 2.0 02/92 EEP Product Considerations

















1 ******************** Page: 7        ********************


  ■ If any objects, including folders and programs, are open and
  running when the system is shut down, only those that were
  started directly from the desktop will restart when the system
  is restarted.

  To ensure that an object automatically starts when the system
  is restarted, move the object from its original folder to the
  desktop. Then, if the object is open when the system is shut
  down, it will start the next time the system is started.


  Desktop Customization

  ■ If you customize your OS/2 2.0 Desktop to OS/2 1.3 or Windows
  3.0, we recommend you read Migrating to the OS/2 Workplace
  Shell  to understand the usability features of your new desktop.
  The book explains how to make OS/2 2.0 look like OS/2 1.3 or
  Windows 3.0.


  DOS Support

  ■ When you start a specific version of DOS from a diskette, be
  sure to insert the diskette in the drive before you start the
  session.


  Windows Support

  ■ Before cutting and pasting to the OS/2 system clipboard from
  or to Windows programs, you must start the Clipboard Viewer
  located in the Productivity folder.
  ■  Bit maps and metafiles greater than 200KB in size will not be
  transferred successfully to the public clipboard.

  ■ Before running WIN-OS/2* in real mode, reset the DOS setting
  EMS_ MEMORY_ LIMIT to 0 for the VDM to be used.

  ■ If you choose to copy an existing Windows desktop
  configuration, it may be necessary to change the MOUSE.DRV
  statement in SYSTEM.INI. If you are currently using a mouse
  that creates a statement other than MOUSE.DRV=MOUSE.DRV
  in the boot.description section of the
  C:\OS2\MDOS\WINOS2\SYSTEM.INI file (where C: is the startup


  Product Considerations7

















1 ******************** Page: 8        ********************


  drive), you will need to change the statement to read
  MOUSE.DRV=MOUSE.DRV
  ■  Be certain that Windows applications have completed their

  initialization before switching back to the OS/2 desktop.


  OS/2 Printing
  ■ Ensure that all print job settings notebooks are closed before
  closing a print object icon or detail view.



  Numeric Coprocessor Emulation

  This version of the product will include a numeric coprocessor
  emulator for use in machines that do not have a numeric
  coprocessor installed. Currently, we are continuing to improve the
  accuracy of the results obtained from this emulator. The results
  obtained from the emulator provided in this version of the product
  may contain errors and cannot be guaranteed.

  Examples of computations which may lead to erroneous results
  are those involving high-precision operations, operations
  combining high-precision operands, boundary conditions such as
  very large or very small quantities, rounding, and underflow.

  If you intend to use floating-point operations in mission-critical
  applications, you must use an 80387 math coprocessor. Installation
  of an 80387 math coprocessor requires a stepping level of B1 or

  higher on the 80386 microprocessor.

  If you are in doubt about whether your application uses
  floating-point operations, contact the application vendor.











  8 OS/2 2.0 02/92 EEP Product Considerations

















1 ******************** Page: 9        ********************



  Local Area Network Support
  ■ Opening a network group folder in a tree may be slow if your
  network contains many servers. It is recommended that you
  use icon view instead.

  ■ The network folder cannot be moved from the desktop.
  ■ The *Alias  server folder displayed by LAN Server 2.0 is not
  functional.

  ■ If you are a LAN Server Network Administrator, do not change
  the printer configuration on a server once it has been shared.

  ■ If you log in as a LAN Server Network Administrator and some
  functions are not available, display the pop-up menu and
  select Refresh. The administrator functions are now available.
  ■ Occasionally, the pop-up menu of a network object might show
  login  when you are already logged in, or logout  when you are
  already logged out. Click on login/logout  and redisplay the

  pop-up menu.
  ■ In this version, do not attempt to access DOS LAN requesters
  from WIN-OS/2 when you are running a specific version of DOS
  in a DOS session.

  Refer to Product Supplemental Information for LAN Server Version
  2.0  for current information regarding network support.



  Peripheral Devices
  ■ When using your Logitech mouse when running in standalone
  DOS, you may experience problems with your mouse under
  OS/2. If so, unplug and then plug in your mouse, or, after
  shutdown, power down and then power up your system.

  ■ When using the COM port on a PS/2* Model 90 or 95 with
  Enhanced set to ON, be sure that the Serial Transmit and
  Serial Receive Arbitration Levels in the hardware configuration
  are set to Dedicated , with different numbers specified.

  For example, when the Serial Port is set to SERIAL 2 in the
  hardware configuration, its corresponding Serial Transmit



  Product Considerations9

















1 ******************** Page: 10       ********************


  Arbitration Level should be set to DEDICATED 3. The Serial
  Receive  Arbitration Level must be set to DEDICATED 4.
  When both levels of a serial port are set to Shared , data

  communication and printing from the COM port with Enhanced
  set to ON will not operate properly. Run the  Setup/Diagnostics
  diskette and follow the instructions on the screen to change
  your hardware configuration.
  ■ The OS/2 2.0 product has been designed to allow most DOS
  and Windows applications to run more reliably than in their

  native environments.
  One or more DOS applications typically can be run
  concurrently in windows while in the background, although
  there are some performance trade-offs when DOS graphics
  applications are run in a window. To realize the full benefits of
  the OS/2 2.0 product, run these applications in full-screen
  sessions.

  There are three cases in which DOS graphics applications may
  be suspended (receive no processor time) when running in the
  background:

  » In the first case, a DOS multiplane application that uses
  advanced graphics, such as 640x480x16 or 640x350x16, will
  be suspended, regardless of the graphics adapter installed,
  if any other DOS application is running in the foreground in
  a full-screen session.

  » In the second case, a multiplane DOS application that uses
  advanced graphics, such as 640x480x16 or 640x350x16, will
  be suspended when a Presentation Manager session is
  running in the foreground in XGA mode. Currently, this
  situation occurs even if you have an Extended Graphics
  Array (XGA) and a Video Graphics Array (VGA) adapter
  connected to your system.

  » In the third case, a multiplane DOS application that uses
  1024x768x16 graphics mode will be suspended when a
  Presentation Manager session is running in the foreground
  in 8514/A mode.
  Note that suspending DOS applications running in the
  background generally poses no problem unless the



  10 OS/2 2.0 02/92 EEP Product Considerations

















1 ******************** Page: 11       ********************


  applications are timing-dependent, such as communications or
  process-control applications. In these cases, suspending them
  may cause them to fail. Avoid this situation by running these
  applications in the foreground in full-screen sessions only. If
  they are graphics applications, run them only in a single-plane
  mode, such as 640x200x2, 320x200x256, or 640x480x2, in
  full-screen sessions.

  Note also that for WIN-OS/2 sessions, set the
  VIDEO_ SWITCH_ NOTIFICATION DOS setting to ON to avoid
  having Windows programs suspended when running in the
  background.

  Personal Computer Manufacturers - Compatibility

  The following list depicts those Personal Computer Manufacturers'
  systems that have passed IBM's compatibility test with the current
  OS/2 2.0 EEP product. IBM's compatibility test verifies (18) key
  functions of the OS/2 2.0 operating system. These test results are
  based on selected model configurations provided by the PCM to

  IBM. This list is preliminary, and IBM will continually update the
  list as we proceed with our testing. Current information will be
  disseminated on various electronic forums and bulletin boards.

  ■ In order for microchannel systems with ESDI hard disks to
  operate properly:

   1. On OS/2 Diskette 1, rename ABIOS.SYS to ABIOS.HLD.
   2. Createa null file called ABIOS.SYS. For example:







  Personal Computer Manufacturers - Compatibility 13

















1 ******************** Page: 14       ********************


  COPY CON: ABIOS.SYS
  blank space
  Enter
  PF6
  Enter
   3. Begin your installation.

  ■ An ABIOS timing condition between OS/2 2.0 and the ALR MPS
  systems can occur during operation. To ensure this condition
  is not encountered, IBM and ALR have agreed to a temporary
  solution. The following change should be made to the
  CONFIG.SYS file on Installation Diskette 1 and after installation,
  ensuring that the same change appears in the CONFIG.SYS file
  on the hard disk.

  Change BASEDEV=IBM1FPLY.ADD
  to BASEDEV=IBM1FLPY.ADD /PS2

  and

  Change BASEDEV=IBM2FLPY.ADD
  to rem BASEDEV=IBM2FLPY.ADD
  After Installation Diskette 4:

   1. Put the Installation Diskette in drive A.

   2. Reboot.
   3. Continue until Diskette1 introduction.

   4. Escape (Esc) from Diskette1 to the A: prompt.
   5. Make the same change to C:\CONFIG.SYS.

   6. Copy IBM1FLPY.ADD to C:\OS2 directory.
   7. Remove the diskette.

   8. Reboot and continue the installation.

  Tips and Techniques

  ■ You can improve the performance of some applications by
  adjusting the DOS settings. If the application does not use
  extended or expanded memory, these values can be set to
  zero:

  » IDLE_ SENSITIVITY
  » EMS_ MEMORY_ LIMIT
  » XMS_ MEMORY_ LIMIT.

  For more information on DOS settings, refer to the OS/2 2.0
  online Master Help Index.
  ■ If you want to use the asynchronous communications device
  interface (ACDI) support in the OS/2 2.0 mini-application called
  PM Terminal, you must edit your CONFIG.SYS file and then

  restart your system. For IBM PS/2 computers, install the
  SASYNCDB.SYS driver:
  DEVICE=C:\OS2\APPS\SASYNCDB.SYS

  For 80386 compatibles, install the SASYNCDA.SYS driver:
  DEVICE=C:\OS2\APPS\SASYNCDA.SYS

  When files are transferred to or from a drive other than drive C
  in PM Terminal, the dialog box may not display all the
  subdirectories. To correct this problem, select the C drive and
  then reselect the correct alternative drive.
  ■ Using the OS/2 Enhanced Editor:

  » The maximum line length is 237 characters.
  » When naming your files, you are unable to use blanks and
  some nonalphanumeric characters, such as double quotes,
  apostrophes, and brackets.

  ■ The FIND option in the OS/2 System Editor does not display the
  results of a search. To view these results, press Alt+F6 to
  move the focus from the Find dialog box to the text entry area.
  ■ We have improved the high-performance file system (HPFS) by

  adding new options that users can specify. Also, we have
  improved both the HPFS and the File Allocation Table (FAT) file
  systems by expanding the read-ahead logic for small-record


  Tips and Techniques 15

















1 ******************** Page: 16       ********************


  input/output (I/O) of less than 512 bytes in size. These
  enhancements are expected to provide faster performance
  when sequential reads are performed.

  Use the IFS= statement to define the maximum I/O record
  size that can be cached using the HPFS.
  ■ By default, 2MB is the amount of memory allocated to each
  WIN-OS/2 session. Currently, we recommend 2MB for each
  WIN-OS/2 session you plan to run.

  If you receive an error indicating that your WIN-OS/2 session
  has insufficient memory, you can try adjusting the memory to
  3MB or 4MB. However, this setting should not be set high
  arbitrarily because the OS/2 swap file (SWAPPER.DAT) will be
  allowed to grow in proportion to the amount of additional
  memory you allocate.

  The optimum size of the swap file is relative to your
  environment. If the swap file is located in its own partition, it
  is preferable to be conservative when you specify the size of
  that partition. These specifications may be helpful.

  4MB system : 7 to 12MB
  6MB system : 5 to 10MB

  ■ OS/2 allows you to run a specific version of DOS in a DOS
  session along with the OS/2 2.0 product. This feature helps to
  ensure compatibility with applications, such as block device
  drivers, that otherwise would be incompatible with the OS/2 2.0
  environment. Currently,

  » If you have already started a version of DOS from a
  diskette, you will not be able to start another version of
  DOS from your hard disk.
  » You may experience problems when starting, or booting,
  DOS from your A drive or from other drives.
  » You cannot start multiple copies of a specific version of
  DOS using a single image. To make multiple images,

  create them on your hard disk using the VMDISK.EXE utility
  located in the \OS2\MDOS\ directory. Change the
  DOS_ STARTUP_ DRIVE DOS setting to start from the image
  you created.

  Applications Considerations

  Temporary Limitations
  IBM has tested many DOS, Windows and OS/2 applications. Most
  of them run unchanged, but some require special attention when
  running on this version of the product. IBM currently plans to
  address these limitations before the OS/2 2.0 product becomes
  generally available. Where available, we have suggested
  temporary work-arounds.

  Other Limitations

  Some categories of applications, usually because of their design or
  because they use undocumented interfaces, will not operate
  properly with the OS/2 2.0 product. IBM is in the process of
  contacting these vendors about resolving these incompatibilities.
  Some vendors have already developed a fix and are willing to
  make the fix available. These have been noted.

  These five categories of applications include:

  ■ Applications that use the DOS Protect-Mode Interface, the
  Expanded Memory Specification (EMS), or the Extended
  Memory Specification (XMS) are supported. Other DOS
  extenders, such as the virtual control-program interface (VCPI),
  that require exclusive access to the 80386 control registers,
  are not supported because they could violate the integrity of
  the system.

  ■ Functions in applications that directly address the physical
  sectors to perform write operations are not supported because
  these operations could violate the integrity of the system.
  ■ Some Windows applications invoke the Windows
  mini-applications to run a subset of function. If you did not
  format your hard disk when you installed this version of the

  product, and if you already had Windows Version 3.0 installed,
  these mini-applications will be invoked automatically.
  ■ Windows applications that require enhanced mode

  ■ DOS or Windows applications that use undocumented DOS or
  Windows interfaces

  24 OS/2 2.0 02/92 EEP Product Considerations

















1 ******************** Page: 25       ********************



  Improvements from the LA Product

  Some of the restrictions identified in the LA Product
  Considerations  document have been corrected in this EEP version
  of the product. These items include:


  Installation Improvements

  ■ A response file can be used to install OS/2 2.0. See the OS/2
  2.0 Installation Guide  for details.

  ■ The DSKBIOS1 function discussed in the LA document is now
  included in the BASEDEV=IBMINT13.I13 CONFIG.SYS
  statement, by default. No special actions are required to
  operate SCSI devices.
  ■ If you select not to install some Productivity and Games

  programs, blank icons representing these programs will no
  longer be installed.
  ■ DOS LAN requesters no longer require that DOS have control
  of the system. They will run on a booted version in a VDM.

  ■ The time needed to install the OS/2 has been reduced.


  Product Considerations Improvements

  OS/2 Workplace Shell

  ■ You can delete multiple objects individually, or you can delete
  them all at one time.

  ■ An icon representing Drive A will appear on the desktop.
  Double-clicking on this icon will now provide access to Drive A.
  ■ The settings notebooks for the Drives objects are now
  operational when displayed from the object's pop-up menu.

  ■ Actions performed on fonts no longer produce inconsistent
  results.

  ■ The time needed to shut down the system has been reduced.



  Improvements from the LA Product 25

















1 ******************** Page: 26       ********************


  Windows Support

  ■ The following items are now described in the OS/2 2.0 online
  or hard copy documentation:
  » Follow the manufacturer's instructions to install Windows
  applications under the OS/2 2.0 product. If the installation
  is unsuccessful, start a full-screen DOS session and try
  again. Another alternative is to choose  Run  from the File

  menu of the WIN-OS/2 Program Manager.
  » To start Windows applications, do one of the following:

  - Install them as separate objects on your desktop.
  - Select Run  from the WIN-OS/2 Program Manager.
  - Type WINOS2  followed by the program name in a
  full-screen DOS or OS/2 session.
  Note that you cannot run DOS applications using Run  from

  the File menu of the Program Manager. They must be run
  from the (OS/2) desktop.
  » OS/2's Dynamic Data Exchange (DDE) feature allows you to
  dynamically update and change data in one running
  program and effect those changes in another running
  program.

  Note that before performing DDE between an OS/2 and a
  Windows application, you must start the Data Update
  object in the Productivity folder.

  » Not all clipboard and DDE data formats are transferable to
  the public clipboard or shared between Windows and PM
  applications.
  » You must run Windows applications in a single WIN-OS/2
  session if you are using private Windows data formats.

  » A set of WIN-OS/2 printer drivers is included with this
  product. When you create an OS/2 printer, you will be
  asked if you want a Windows-equivalent configuration, if
  one is available. You also will be asked to install a
  WIN-OS/2 printer driver.

  If a WIN-OS/2 printer is not automatically installed during
  OS/2 installation, you can install WIN-OS/2 printer drivers



  26 OS/2 2.0 02/92 EEP Product Considerations

















1 ******************** Page: 27       ********************


  from the WIN-OS/2 Control Panel. WIN-OS/2 printer drivers
  are located on the Printer Driver Diskettes 1-6.
  If you want to use a Windows printer driver that is not

  automatically installed by OS/2, or is not shipped with
  OS/2, configure the Windows printer driver to use an OS/2
  port that has the IBMNULL printer driver associated with it.
  The IBMNULL printer driver is installed during system
  installation. If IBMNULL is not displayed in the list of
  available printer drivers, use the Install  pop-up menu
  choice on an existing printer driver to display the Printer
  Driver Install dialog box.

   1. Insert Printer Driver Diskette1 in your diskette drive;
  then select Refresh.
   2. Select IBMNULL from the list; then select Install.
   3. Select Cancel; then select IBMNULL for the Printer
  object.

  Note that LPT1.OS2 and LPT2.OS2 support better
  performance than LPT1 or LPT2 when configuring from the
  WIN-OS/2 Control Panel.
  ■ Performing DDE between two Windows applications running in
  separate sessions or between a Presentation Manager (PM)
  and a Windows application currently no longer cause the
  Windows application running in the background to be

  suspended (receive no processor time).
  ■ If the Windows clipboard is set to public, requests to print the
  screen from a Windows session (using PrintScreen) are now
  successful.

  ■ The contents of the clipboard are no longer lost if you exit from
  a Windows application during a cut, copy, or paste operation.
  ■ Bit-map files and metafiles can be converted compatibly

  between Windows and PM applications when operating in all
  video modes.
  ■ To install your Windows LAN device drivers and configure
  WIN-OS/2 to use these device drivers, run SETUP.EXE from the
  WIN-OS/2 full screen session.

  ■ It is not necessary to define a Windows printer if you are
  installing Windows multimedia extensions under this version.


  Improvements from the LA Product 27

















1 ******************** Page: 28       ********************


  ■ Like Windows, the OS/2 2.0 product automatically installs
  corresponding Windows mouse and printer drivers when you
  select a Presentation Manager*  mouse driver.

  ■ On systems with an XGA adapter connected, starting Windows
  from a full-screen session and then closing the session no
  longer causes the screen to behave inconsistently.

  OS/2 Printing

  ■ You can now delete any printer device drivers from the Printer
  object. Doing so no longer causes subsequent attempts to
  reinstall these drivers to fail.

  Peripheral Devices

  ■ The DOS DISKCOPY command now operates properly when
  used on an external 5 1/4-inch diskette drive.


  Tips and Techniques Improvements

  ■ The OS/2 mini-application called Cat and Mouse is now
  operational.
  ■ Closing a DOS or Windows session from the Window List or
  from a pop-up menu, while an application is running in that
  session, no longer causes subsequent attempts (by these

  sessions) to access devices to fail.
  ■ HPFS performance for 2KB and 4KB I/O has been improved.

  ■ All networking applications may now start from the Drives
  objects.













  28 OS/2 2.0 02/92 EEP Product Considerations

















1 ******************** Page: 29       ********************


  ■ The following items are now described in the OS/2 2.0 online
  documentation:
  » Adjusting these DOS settings for Windows full-screen

  objects or other Windows program objects, may boost the
  performance of applications running in Windows sessions.
  KBD_CTRL_BYPASS = CTRL_ESC This setting allows the WIN-OS/2
  Program Manager to recognize
  a Ctrl+Esc and then
  display the Task List.

  MOUSE_EXCLUSIVE_ACCESS = ON This setting allows WIN-OS/2
  (in place of the PM)
  to control the Mouse pointer
  if you run a WIN-OS/2
  session in a window.

  VIDEO_SWITCH_NOTIFICATION = ON This setting notifies a DOS
  program to do its own save
  and restore of the video state.

  VIDEO_8514A_XGA_IOTRAP = OFF This setting must be set so
  that DOS and WIN-OS/2 sessions
  can continue to run when in the
  background (for systems with
  8514/A and XGA adapters only).


  » The performance of DOS applications is optimal when
  running in full- screen sessions. You can press the
  Alt+Home keys to run your DOS applications in full-screen
  DOS sessions.
  » If you are running Windows and have an 8514 Windows

  video adapter (8514.DRV) installed, do not change the
  default settings for VIDEO_ SWITCH_ NOTIFICATION and
  VIDEO_ 8514_ XGA_ IOTRAP.
