Installing OS/2 2.1 ServicePak Beta

   Welcome to OS/2* 2.1.  This document provides
   you with information you need before you
   install OS/2 2.1.  It contains helpful hints
   found in our testing as well as updates and
   corrections to the "OS/2 2.1 Installation
   Guide".

   Use the information in conjunction with the
   "OS/2 2.1 Installation Guide" and the "OS/2 2.1
   Using the Operating System" manual.

   ****************Important!*****************

     Do not install this BETA release on a PS/2 Mod 95
     with 20 MB of RAM.  This configuration will fail on
     the Install disk.

     If you are attempting to use CID to install client
     workstations, you must install the workstation using
     the FAT file system.

     If you are installing OS/2 2.1 over a
     product release such as OS/2 1.x, OS/2
     2.0, OS/2 2.0 with the Service Pak, DOS,
     or DOS and Windows**, you do
     not need to reformat the OS/2 partition.
     If you choose to format the partition, your
     hard disk will be erased and you will have
     to re-install your application and pre-installed
     utilities.

     If you are installing OS/2 2.1 over an
     existing OS/2 2.0 system in which you
     have application programs on the desktop,
     you should not elect to migrate these
     applications during your installation.
     Your current application set will
     continue to be available to you after
     installation.

     If you have a version of the OS/2 2.1 beta
     installed, you need to reformat the OS/2
     partition.  Installing OS/2 2.1 over a
     previous beta version is not supported.
     Do not use any OS/2 system files (such as
     OS2.INI or OS2SYS.INI) from a previous
     beta version.

     If you have a DOS system with compression
     activated, do one of the following:

       1.  Decompress the disk

       2.  Select a different partition

       3.  Format the disk

     If you are installing OS/2 2.1 on a non-Micro Channel (MCA)
     system, change the settings in your CMOS to the following:

       o  Turbo/System Speed should be OFF/Slow
       o  Caching (External) should be OFF
       o  ROM Shadowing (System and Video) should be OFF

     These settings affect the way that OS/2 2.1 installs.
     Failure to change these settings might result in OS/2 not
     installing at all; installing and then booting to a Trap 2;
     or what seems to be a good install and later have unexplainable
     random Traps (from a few days to a few months later).

     To improve system performance after you have installed OS/2,
     all of the above settings can be changed back without causing
     damage to OS/2.



CREATING DISKETTES FROM THE OS/2 CD

   You use the LOADDSKF utility program to create
   the diskettes.  (LOADDSKF.EXE is in the
   \DISKIMGS directory of the CD. LOADDSKF can be
   run from either the DOS or OS/2 operating
   system.)

   In the following sections, you will see lists
   of the product diskettes for OS/2 2.1 and the
   actual diskette names as they exist on the CD.
   For each diskette image file, use LOADDSKF to
   expand the image to its own diskette.  (Note
   that you must use formatted diskettes for this
   procedure.)

   For example:

      cddrive:\DISKIMGS\LOADDSKF cddrive:\DISKIMGS\OS2\size\disk_name d:

   where:

       cddrive is the drive letter of the CD-ROM

       size is 35 for 3.5-inch diskettes or 525
       for 5.25-inch diskettes

       disk_name is the diskette image file name
       (for example, DISK0.DSK, PMDD1.DSK.)

       d is the drive letter of your diskette
       drive (A: or B:)

   After you create all the diskettes (20 for
   3.5-inch diskettes or 24 for 5.25-inch
   diskettes), insert the DISK0 diskette in drive
   A:, restart your system, and follow the
   instructions to install OS/2 2.1.

   If you want to create diskettes for the
   Multimedia support that is part of OS/2 2.1,
   note that the images are located in the
   \DISKIMGS\MMPM2 directory. Use LOADDSKF to
   expand each image to its own diskette.  For
   example:

       cddrive:\DISKIMGS\LOADDSKF cddrive:\DISKIMGS\MMPM2\size\disk_name d:

   where:

       cddrive is the drive letter of the CD-ROM

       size is 35 for 3.5-inch diskettes or 525
       for 5.25-inch diskettes

       disk_name is the diskette image file name
       (for example, DISK1.DSK)

       d is the drive letter of your diskette
       drive (A: or B:)

   NOTE: Use previously formatted diskettes for
   the target (d:).

   SCSI-BASED CD-ROM SUPPORT
   _________________________

   The majority of SCSI-based CD-ROM drives and
   adapters are supported by OS/2 2.1.
   ("SCSI-based" refers to the small computer
   system interface (SCSI), a standard
   input/output interface used by personal
   computers.)

   A complete list of the CD-ROM drives and SCSI
   adapters tested on OS/2 2.1 can be found in the
   "Hardware Support" chapter of the "OS/2 2.1
   Using the Operating System" manual.


OBTAINING ADDITIONAL CD-ROM SUPPORT

   If, after reviewing the list in "OS/2 2.1 Using
   the Operating System", you find that your
   CD-ROM drive or SCSI adapter is not supported
   within the OS/2 product, you can contact the
   manufacturer and obtain an OS/2 Adapter Device
   Driver (.ADD) file.  After you receive the .ADD
   file, follow the instructions in the "Before
   You Begin" section of the "OS/2 2.1
   Installation Guide" to add this file to
   Diskette 1.

   As an alternative, you can create installation
   diskettes from the diskette images that are on
   the OS/2 CD, if you have DOS support for your
   CD-ROM drive.

   If support for your CD-ROM was not properly
   installed during initial installation of OS/2
   2.1, then you will need to use the Selective
   Install program located in the System Setup
   folder to reinstall the CD-ROM support
   appropriate for your CD-ROM.


NON SCSI-BASED CD-ROM SUPPORT FOR SONY, PANASONIC and MITSUMI
_____________________________________________________________

   In order for the Sony, Mitsumi and Panasonic non-SCSI CD-ROM drives
   to be recognized by OS/2, the base I/O port address specified on the
   CD-ROM's BASEDEV statement in config.sys must match the base
   I/O port address specified on the CD-ROM's host adapter card.

   NOTE: If you are installing OS/2 2.1 from CD-ROM, you may first be
         required to modify the BASEDEV statement for your CD-ROM device
         driver in the CONFIG.SYS file on the diskette labeled Diskette 1.

   The section below indicates the required parameter switch settings
   for each CD-ROM drive.



   The following examples illustrate how the CD-ROM drives are attached to
   the most common host adapters.

   Modifying CONFIG.SYS for the Sony CDU-31A driver (SONY31A.ADD)
   --------------------------------------------------------------

   1.  Sony CDU-31A CD-ROM drive attached to Sony CDB-334 host adapter:

       The Sony CDB-334 host adapter supports base I/O port addresses of
       320h, 330h, 340h or 360h. If the CDB-334 host adapter is set to
       its default port address of 340h, the statement in config.sys does
       not need to be modified and should appear as follows:

           BASEDEV=SONY31A.ADD

       If the CDB-334 host adapter is set to any port address other
       than the default of 340h, the config.sys statement needs to be
       modified. For example, if the Sony CDB-334 host adapter is set
       to a base I/O port address of 360, the line in config.sys should be:

           BASEDEV=SONY31A.ADD /A:0 /P:0360


   2.  Sony CDU-31A CD-ROM drive attached to Media Vision ProAudio
       Spectrum-16 host adapter:

       The line in config.sys needs to be modified and should appear
       as follows:

           BASEDEV=SONY31A.ADD /A:0 /AT:08


   3. Sony CDU-31A CD-ROM drive attached to the Creative Labs Sound
      Blaster Pro, Sound Blaster 16, or Sound Blaster 16 MultiCD
      host adapter:

      The port address specified on the BASEDEV statement in config.sys
      should be 10h above the base I/O port address specified on the adapter
      card.  For example, if the Sound Blaster card is set for a base
      I/O port address of 220h, the line in config.sys should be:

           BASEDEV=SONY31A.ADD /A:0 /P:0230


   Sony CD-ROM Device Driver Parameters
   ---------------------------------------

   The parameters for the following CD-ROM adapter device drivers are
   described in this section:


   SONY31A.ADD


   This device driver supports the following CD-ROM drives:

   Sony CDU-31A
   Sony CDU-7305


   Parameter Definitions
   ---------------------


   /A:n          Identifies a specific adapter, n.  The adapter is
                 specified  as a single digit value which is zero based.
                 (i.e. The first adapter is specified as /A:0).


   /AT:dd        Sets the adapter type connected to the CD-ROM drive.

                 Supported values are:
                     00 = Sony CDB-334 (default)
                     08 = Media Vision ProAudio Spectrum-16


   /P:nnnn       Specifies the base I/O port address of the interface card.
                 This must be the same number as specified on the interface
                 card.

                 If this parameter is not specified, the default port
                 address for the host adapter is used.  For the Sony
                 CDB-334 host adapter, the default is 0340.  For the Media
                 Vision ProAudio Spectrum-16 card the default is 1F88.


   /I:nn         Specifies the interrupt request (IRQ) channel number.
                 This must match the IRQ value selected on the host
                 interface card.  If this parameter is not specified,
                 the device driver will use software polling transfer.

                 Note: Some Sony host adapter cards did not ship with the
                 plastic jumper switch to select the IRQ channel on the IRQ
                 jumper block. You must obtain and install the plastic
                 jumper switch to enable the IRQ channel.


   /V            Verbose. The device driver will display the device driver
                 revision level and CD-ROM product identification
                 information at boot time.


   Parameter Examples
   ------------------

   1.  Sony CDU-31A CD-ROM drive attached to Sony CDB-334 host adapter:

       The Sony CDB-334 host adapter supports base I/O port addresses of
       320h, 330h, 340h or 360h. If the CDB-334 host adapter is set to any
       port address other than the default of 340h, the config.sys
       statement needs to be modified. For example, if the Sony CDB-334
       host adapter is set to a base I/O port address of 360, the line in
       config.sys should be:

           BASEDEV=SONY31A.ADD /A:0 /P:0360


   2.  Sony CDU-31A CD-ROM drive attached to Media Vision ProAudio
       Spectrum-16 host adapter:

   3. Sony CDU-31A CD-ROM drive attached to the Creative Labs Sound
      Blaster Pro, Sound Blaster 16, or Sound Blaster 16 MultiCD
      host adapter:

      The port address specified on the BASEDEV statement in config.sys
      should be 10h above the base I/O port address specified on the
      adapter card.  For example, if the Sound Blaster card is set for a
      base I/O port address of 220h, the line in config.sys should be:

           BASEDEV=SONY31A.ADD /A:0 /P:0230


   4.  To enable interrupt transfer mode, which improves performance,
       the /I parameter must be specified.  For example to enable
       interrupt transfer mode for IRQ channel 5 at I/O port address
       of 360h, the line in config.sys should appear as follows:


           BASEDEV=SONY31A.ADD /A:0 /P:0360 /I:5

       from 300h to 3FCh.  If the Mitsumi host adapter is set
       to a base I/O port address of either 300h, 310h, 340h, 360h
       or 390h, the statement in config.sys does not need to be
       modified and should appear as follows:

           BASEDEV=MITFX001.ADD

       If the Mitsumi host adapter is set to an address other than
       those specified above, the BASEDEV statement needs to be modified.
       For example, if the Mitsumi host adapter is set to a base
       I/O port address of 320, the line in config.sys should be:

           BASEDEV=MITFX001.ADD  /P:320


   2.  Mitsumi CD-ROM drive attached to Creative Labs
       Sound Blaster 16 MultiCD

       For example, if the Mitsumi CD-ROM port on the Sound Blaster
       16 MultiCD is set to I/O port address of 320, the line in
       config.sys should be:


           BASEDEV=MITFX001.ADD  /P:320



   Mitsumi CD-ROM Device Driver Parameters
   ---------------------------------------

   The parameters for the following CD-ROM adapter device drivers are
   described in this section:


   MITFX001.ADD


   This device driver supports the following CD-ROM drives:

   Mitsumi CRMC-FX001D
   Mitsumi CRMC-FX001
   Mitsumi CRMC-LU005S

   Parameter Definitions
   ---------------------

   /P:nnn        Specifies the base I/O port address of the interface card.
                 This must be the same number as specified on the interface
                 card.


   /I:nn         Specifies the interrupt request (IRQ) channel number.
                 This must match the IRQ value selected on the host
                 interface card.  If this parameter is not specified,
                 the device driver will use software polling transfer.


   /V            Verbose. The device driver will display the device driver
                 revision level and CD-ROM product identification
                 information at boot time.


   Parameter Examples
   ------------------

   1.  Mitsumi CD-ROM drive attached to Mitsumi host adapter:

       If the Mitsumi host adapter is set to a base I/O port address
       of 320, the line in config.sys should be:

           BASEDEV=MITFX001.ADD  /P:320


   2.  Mitsumi CD-ROM drive attached to Creative Labs Sound Blaster 16 MultiCD.
       For example, if the Mitsumi CD-ROM port on the Sound Blaster
       16 MultiCD is set to I/O port address of 320, the line in
       config.sys should be:


           BASEDEV=MITFX001.ADD  /P:320


   3.  To enable interrupt transfer mode, which improves performance,
       the /I parameter must be specified.  For example to enable
       interrupt transfer mode for IRQ channel 10 at I/O port address
       of 320h, the line in config.sys should appear as follows:


           BASEDEV=MITFX001.ADD  /P:320 /I:10



   KNOWN BUGS
   ----------

   If the OS/2 installation program hangs in the middle of installing,
   just after the intermediate reboot, but before the System Configuration
   screen is displayed, do the following:

   1.  Insert a DOS diskette in A: and reboot
   2.  Edit the config.sys on the OS/2 boot partition and comment out the
       following lines in config.sys:

       a.  If you are installing from the Creative Labs, Panasonic or IBM
           ISA non-SCSI CD-ROM drives, then comment out the following lines

              REM BASEDEV=SONY31A.ADD
              REM BASEDEV=MITFX001.ADD

       b.  If you are installing from the Sony 31A CD-ROM drive then
           comment out the following lines:

              REM BASEDEV=SBCD2.ADD
              REM BASEDEV=MITFX001.ADD

       c.  If you are installing from the Mitsumi CD-ROM drive then comment
           out the following lines:

              REM BASEDEV=SBCD2.ADD
              REM BASEDEV=SONY31A.ADD


       d.  If you are installing from any other CD-ROM drive or from
           diskettes then comment out the following lines:

              REM BASEDEV=SBCD2.ADD
              REM BASEDEV=SONY31A.ADD
              REM BASEDEV=MITFX001.ADD

   3.  Remove the DOS diskette from A: and reboot.  Continue with OS/2
       installation.




HARDWARE CONSIDERATIONS
_______________________

   If you have a Quantum hard card, you must make
   a modification to the BASEDEV=IBM1S506.ADD line
   in the CONFIG.SYS file of Diskette 1 before you
   install OS/2 2.1.  The BASEDEV statement should
   be modified as follows:

       BASEDEV=IBM1S506.ADD /A:1 /IRQ:11

   (These are the default settings for the Quantum
   hard card.)

   If you have added a device driver statement to
   the CONFIG.SYS file on diskette 1 and later
   migrate your old CONFIG.SYS file, make sure
   there are not two copies of this statement in
   your file.  If you have two copies of this
   statement in your file, REM one statement out.

   If you have a Logitech** TrackMan**, select one
   of the two Logitech mouse choices during
   installation.


INSTALLING OS/2 2.1 FROM A CD ON AN IBM THINKPAD ATTACHED TO A DOCKING STATION
______________________________________________________________________________

   If you are installing OS/2 2.1 on an IBM*
   ThinkPad* 700, 700C, 720, or 720C attached to a
   3550 Docking Station, you need to replace the
   ABIOS files on the OS/2 Installation Diskette
   with files from the Reference Diskette.  Do the
   following:

   1.  Detach the ThinkPad from the Docking
       Station.

   2.  Create a Reference Diskette (if you have
       not already done so) by following the
       documentation that came with the ThinkPad.

   3.  Make a copy of the OS/2 Installation
       Diskette.

   4.  Insert the original OS/2 Installation
       Diskette into drive A.

   5.  Turn on the computer.  If it is already on,
       press Ctrl+Alt+Del.

   6.  When you are prompted to do so, remove the
       Installation Diskette, insert Diskette 1,
       and press Enter.

   7.  When the Welcome screen is displayed, press
       Esc to display the command prompt.

   8.  Insert the copy of the Installation
       Diskette into drive A.

   9.  Type:

            DEL *.BIO

       and press Enter.

   10. Remove the copy of the Installation
       Diskette, and insert the Reference Diskette
       you created in step 2 into drive A.

   11. If your computer has more than one diskette
       drive, insert the copy of the Installation
       Diskette into drive B.  Otherwise, in the
       next two steps, you will be prompted to
       insert diskettes into both drive A and
       drive B.  When you are asked to insert a
       diskette into drive A, insert the Reference
       Diskette.  When you are asked to insert a
       diskette into drive B, insert the copy of
       the Installation Diskette.

   12. Type:

            COPY A:\*.BIO B:\

       and press Enter.

   13. Type:

            COPY A:\ABIOS.SYS B:\

       and press Enter.

   14. Power off the ThinkPad and return it to the
       Docking Station.

   15. Restart the installation procedure by
       inserting the copy of the Installation
       Diskette into drive A.


INSTALLING OS/2 2.1 USING RIPL
______________________________

   When installing OS/2 2.1 using the IBM LAN
   Server 2.0 and 3.0 Remote Installation Program
   Load (RIPL), the 2.1 version of RIPLINST.EXE is
   dependent upon the 2.1 version of UNPACK.EXE.
   Therefore, if you are using the 2.1 version of
   RIPLINST.EXE on a client machine with OS/2
   version 2.0 or lower, then you must copy the
   UNPACK.EXE file to the client machine.  To do
   this, do the following:

   1.  Insert OS/2 2.1 Diskette 2 into drive A

   2.  At an OS/2 command prompt type:

            copy a:\unpack.exe \os2\unpack.exe

       After copying the file to the client
       machine, you can now execute the 2.1
       version of the RIPLINST.EXE program.


EXTENDED SERVICES (ES) 1.0
__________________________

   o   If you installed OS/2 2.1 on a system that
       already had Extended Services installed,
       replace the existing ESSTART.CMD file with
       the ESSTART.BAK file that was installed by
       OS/2 2.1.  (The ESSTART.BAK file is located
       in the OS2\INSTALL subdirectory.)

   o   If you are installing Extended Services
       over OS/2 2.1 for the first time (that is,
       there is no Extended Services on the
       workstation), or if you are installing
       Extended Services from diskettes, rename
       the existing ESSTART.CMD file from the
       Extended Services Diskette 1.  Then, copy
       the file ESSTART.BAK from the \OS\INSTALL
       directory to Extended Services Diskette 1.
       Finally, rename the ESSTART.BAK file
       ESSTART.CMD, and begin the installation of
       Extended Services.


VIDEO CONSIDERATIONS
____________________

   The following information pertains to video
   support for OS/2 2.1.


INSTALLING SUPER VGA (SVGA) SUPPORT

   After the VGA installation is complete, follow
   the procedure "Installing Support for Super VGA
   (SVGA)" in Appendix A of the "OS/2 2.1
   Installation Guide".


INSTALLATION ON SPECIFIC VIDEO ADAPTERS

   In the "OS/2 2.1 Installation Guide",
   instructions are given for configuring the
   ATI** Graphics Ultra Pro.  These instructions
   state that the monitor type for 640 x 480 must
   be configured to IBM DEFAULT.  Note that this
   setting might be referred to as 60Hz rather
   than IBM DEFAULT.

   The Radius XGA display adapter is supported on
   PS/2* Models 35 and 40 and PS/ValuePoint* 486
   systems.  If you are using the display adapter
   on a PS/ValuePoint system, the VPXGA.EXE
   utility is required.  For a copy of this
   utility program, check your Radius installation
   diskette or contact Radius.

   The OS/2 2.1 operating system cannot restore
   the state of a Sigma Legend** display adapter
   after you switch sessions or video modes.
   Also, the Sigma Legend video adapter might
   cause the system to stop when using 1024 x 768
   x 256 color mode.  Use only 640 x 480 or 800 x
   600 mode with this adapter.

INSTALLATION FROM DISKETTE
--------------------------

This video accelerator driver is compatible with OS/2 2.1.  Do not install it
on previous versions of OS/2.

To install this S3 video accelerator driver from diskette:

    1.  Place this diskette into drive A (or any other diskette drive).

    2.  Open an OS/2 full-screen or OS/2 window session.

    3.  At the OS/2 command prompt, type the following command:

        A:S3INST A: C:

             where:  A: is the diskette drive
                     C: is the drive where OS/2 2.1 is installed

        This command will copy all necessary files to the OS/2 drive.

    4.  Remove the diskette from the diskette drive, perform a shutdown, and
        then restart the system.

    5.  Open the "OS/2 System" folder.

    6.  Open the "System Setup" folder.


    7.  Open the "Display Driver Install" (DSPINSTL) object.

        When the Display Driver Install window appears, "S3" should be the
        default choice.  Select "OK".

        When the Monitor Configuration/Selection Utility window appears,
        the "Install Using Defaults for Monitor Type" option is preselected.
        You can accept this option or select the "Install Using Display Adapter
        Utility Program" option.

        NOTE:  If you select the Install Using Display Adapter Utility
               Program option, follow the instructions on your screen.
               For additional information about this option, you can
               refer to pages 114 and 115 in the "OS/2 2.1 Installation
               Guide".

     8. When the source directory pop-up window appears, insert the S3
        Video Accelerator Driver diskette and select Install.

        DSPINSTL determines the hardware configuration by creating the
        SVGADATA.PMI file on the drive where the OS2 directory is located.
        If the SVGADATA.PMI file has not been created, the adapter will not be
        supported.

     9.  When the installation is complete, do the following:
         a.  Open "OS/2 System".
         b.  Open "System Setup".
         c.  Open the "System" object.  The Screen page of the Settings
             notebook lists all the supported resolutions for your
             configuration.
         d.  Select a resolution; then, close the notebook.

    10.  Perform a shutdown; then, restart the system.

Note that during the installation of this driver a DISPLAY.LOG file is
created in the OS2\INSTALL directory.  This file identifies the OS/2 2.1 system
files that were updated and indicates whether the installation was successful.
The contents of this file might be useful if you need to report an
installation problem to IBM.



COMPATIBILITY

FUNCTIONAL RESTRICTIONS
-----------------------

         o  After Dark** for Windows** images that move from left to right do
            not perform properly at 640x480x16M resolution.

         o  To avoid a General Protection fault while loading Ventura
            Publisher** for Windows be sure it is in one of the 256 color
            resolutions.

         o  To avoid a trap in Lotus** 1-2-3** for OS/2 do not attempt to run
            the program at 16.7 million colors.

         o  WordPerfect** 5.1 and 5.2 for Windows produce a general protection
            fault when the "Print Preview" option is selected while using
            800x600x64K or 600x480x16 million color mode.

         o  Users of the software motion video feature of MMPM/2 should
            expect satisfactory results in 256-color modes.  However, in
            64K-color modes, users of the feature will experience unusual
            results.  An OS/2 2.1 pervasive fix package will be available
            electronically.  The software motion video feature is not
            supported in 16 million color modes.

            In addition, the software motion video feature will take
            advantage of a 1MB aperture on video adapters and systems where it
            is available to improve the performance of video playback in
            64K-color modes.  For those systems with nonstandard locations,
            the actual physical address of the aperture must be provided in
            the following CONFIG.SYS statement:

               SET VIDEO_APERTURE=xxxh

            where "xxx" is a hexadecimal value in units of 1MB, representing
            the actual physical address to map to the aperture.  For example,
            the IBM PS/ValuePoint Systems must have the statement:

               SET VIDEO_APERTURE=400h

            to use a physical address at 1GB.


INSTALLATION IN A CID ENVIRONMENT
----------------------------------

        NOTES:

         1.  The server must contain a directory named S3_DRVS on the same
             drive where the OS/2 2.1 diskettes reside.  The S3_DRVS directory
             must contain all of the files from the S3 Video Accelerator
             Driver diskette.

         2.  OS/2 2.1 must have been successfully installed on the client
             using the CID Method.

To install the S3 video accelerator driver using CID, use the following
information to modify your LCU command file.

        NOTE:  The following information is meant as a guide, your LCU command
               file might be different.

                     /PK:SVGA where SVGA is the primary adapter key
                     /SK:NONE where NONE is the secondary adapter key
                     /S:X:\ where X:\ is the redirected source path
                     /T:C: where C: is the drive where OS/2 2.1 is installed
                     /MC:8 is the manufacturing code that distinguishes S3.

   NOTE:  After the S3 video accelerator driver has been successfully
          installed on the client machine using the CID method and the client
          machine is restarted, the default resolution will be 640x480x256.

NEW SETVGA PROCEDURE
--------------------

Use the following procedure instead of the SETVGA command to return to
VGA mode.

        NOTE:  If your display is out of sync, start OS/2 using the OS/2
               Installation Diskette, insert Diskette 1 when prompted, then
               press Esc to access a command prompt.  Follow the instructions
               below to reset your display mode.

o  If you installed OS/2 from diskettes:

     1.  Be sure RSPDSPI.EXE is in the \OS2\INSTALL directory.  If it is, go
         to step 2.  If it is not, insert Installation Diskette 8 and unpack
         RSPDSPI.EXE with the following command:

         C:\OS2\UNPACK A:\INSTAID C: /N:RSPDSPI.EXE

             where:  A: is the drive containing Installation Diskette 8
                     C: is the drive where OS/2 2.1 is installed

     2.  Type C:; then press Enter
     3.  Type CD C:\OS2\INSTALL; then press Enter
     4.  Type RSPDSPI /PK:VGA /SK:NONE /S:A:\ /T:C:; then press Enter

             /T:C: where C: is the drive where OS/2 2.1 is installed
             /S:A: where A: is the diskette drive you use to install
                   OS/2

o  If you installed OS/2 from CD-ROM or a LAN:

     1.  Be sure RSPDSPI.EXE is in the \OS2\INSTALL directory.  If it is, go
         to step 2.  If it is not, unpack RSPDSPI.EXE with the following
         command:

         C:\OS2\UNPACK E:\DISK_8\INSTAID C: /N:RSPDSPI.EXE

             where:  C: is the drive where OS/2 2.1 is installed
                     E: is the CD-ROM or LAN drive

     2.  Type C:; then press Enter
     3.  Type CD C:\OS2\INSTALL; then press Enter
     4.  Type RSPDSPI /PK:VGA /SK:NONE /S:E:\OS2SE21\ /T:C:; then press Enter

             /T:C: where C: is the drive where OS/2 2.1 is installed
             /S:E: where E: is the CD-ROM or LAN drive
