        __________________________________


  PCMCIA COMMUNICATION DEVICE
  ___________________________

  If you currently have a PCMCIA communication device
  (modem or fax/modem), you must check your CONFIG.SYS
  file to ensure proper placement of the following
  device statement:

    DEVICE=C:\OS2\PCMCIA.SYS

  This statement must be located before the COM.SYS
  device statement, or your communications device might
  not function.


                                           Page 2


  THINKPAD 750C
  ____________________________

  o   After installing this version of the ServicePak,
      you might find that your DOS full screen session
      does not work correctly.

      To fix this problem:
      -   You MUST reinstall the video driver from the
          ThinkPad video features diskette.

  o   If you experience a video problem with the
      ThinkPad 750c, do the following:

      1.  Start your system using the Installation diskette

      2.  Type SETVGA X: (where X=your OS/2 start up drive)

          and then press Enter

      3.  Edit your CONFIG.SYS file

          type:  REM
                 in front of the following statements:

            SET SPRITEENABLE=ON
            RUN=CHKRES.EXE
            SET HARDWAREBITBLIT=ON

      4.  Restart your system, then reinstall the
          ThinkPad 750c video drivers.

  o   If you are using an IOMEGA PC Powered Pro 9 adapter,
      you must call the IOMEGA service number and request
      OAD Driver Version 2.3.


                                           Page 3


  DESKTOP
  ______________________

  o   You will notice that the default color scheme has
      changed for OS/2 for Windows ServicePak.
  o   After you install this ServicePak, and you want
      to return to the desktop layout of your previous
      version of OS/2 you must press Alt-F1 prior to
      and up until the OS/2 logo screen is displayed
      while booting your system.  This will restore

      prior to installing this ServicePak.


                                           Page 4


  PRINTER
  _______________________

  If you need to add a Windows printer driver after
  installing this ServicePak, you must install the
  printer driver from the Windows Control Panel.  Then,
  use the OS/2 Printer object to install the
  corresponding OS/2 printer driver.

  The OS/2 printer drivers on the OS/2 for Windows
  ServicePak printer driver diskettes are stored in a
  packed format that is not compatible with OS/2 1.3 or
  2.0.  To install one of the OS/2 for Windows
  ServicePak printer drivers on a system with OS/2 1.3
  or 2.0 installed, you must first unpack the driver on
  a system that has OS/2 for Windows ServicePak
  installed.  You do not have to complete these steps
  to install a printer driver on a system that already
  has OS/2 for Windows ServicePak installed.

  NOTE:  Do not install the new 32-bit PostScript
         driver (PSCRIPT.DR_) that came with OS/2 for
         Windows ServicePak on a system with OS/2 1.3
         or 2.0 installed.  It is not compatible with
         these versions of OS/2.  While testing is
         continuing, current compatibility information
         about tested systems is available through your
         dealer, Marketing Representative, CompuServe,
         IBM National Support Center Bulletin Board
         System (NSC BBS), and IBMLink.


                                           Page 5


  To unpack a printer driver for use on a OS/2 1.3 or
  OS/2 2.0 system, complete the following steps on your
  system that has OS/2 for Windows ServicePak
  installed.
  1.  Open the OS/2 System folder.

  1.  Open the OS/2 Command Prompt folder.

  2.  At the command prompt type:

        MD X:\DRIVER

      Where X is a drive on your system.

  3.  Insert into drive A the OS/2 for Windows
      ServicePak printer driver diskette that contains
      the printer driver you want to install.  The
      printer driver names end in a "_".

        Printer Driver:  Diskette #   Packed Name:
        IBM Null            1         IBMNULL.DR_
        HP LaserJet         1         LASERJET.DR_
        HP DeskJet          1         HPDJPM.DR_
        IBM 52XX            1         IBM52XX.DR_
        Epson               1         EPSON.DR_
        Plotter Driver      1         PLOTTERS.DR_
        IBM 4019            2         IBM4019.DR_
        IBM 42XX            2         IBM42XX.DR_

        PaintJet            2         SMGXPJET.DR_

      NOTE:  In order to get the proper printer driver
             directory structure on systems with OS/2
             1.3, IBMPCL3, IBMPCL5, HPDeskJet and
             PaintJet must be installed using the
             Printer Install option in the Print
             Manager.  Do not use the Control Panel to
             install these printer drivers.

  4.  Type:

        UNPACK A:\Packed name X:\DRIVER

      Where X is a drive on your system.  For example
      if you want to install the Epson printer driver,
      type:

        UNPACK A:\EPSON.DR_ X:\DRIVER

      The printer driver files are now unpacked in the
      X:\DRIVER directory.

  5.  Copy the driver files to a diskette and install
      them onto your OS/2 1.3 or 2.0 system.

  EXTENDED SERVICES (ES) 1.0
  _________________________________________

  If you installed OS/2 for Windows ServicePak 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 for
  Windows ServicePak.  (The ESSTART.BAK file is located
  in the OS2\INSTALL subdirectory.)

  If you are installing Extended Services over OS/2 for
  Windows ServicePak for the first time (that is, there
  is no Extended Services on the workstation), or if
  you are installing Extended Services from diskettes:

  1.  Rename the existing ESSTART.CMD file from the
      Extended Services Diskette 1.
  2.  Copy the file ESSTART.BAK from the \OS\INSTALL
      directory to Extended Services Diskette 1.
  3.  Rename the ESSTART.BAK file ESSTART.CMD
  4.  Begin the installation of Extended Services.

  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 for Windows
  ServicePak, 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.


                                          Page 17


  INSTALLING WITH CID AND SEMAINT
  _______________________________

  If you use SEMAINT to create maintenance systems to
  apply the ServicePak, statements are added to the
  CONFIG.SYS file created by SEMAINT.  These statements
  enable swapping to the target drive and directory of
  the maintenance system.  This path is determined by
  the /T:  parameter that SEMAINT uses when it is
  started.  Swapping is enabled only on systems with 10
  megabytes of RAM or less.  The initial swap file size
  will be set to 1024KB or 1 megabyte and can grow
  depending on the amount of virtual memory needed
  during installation of the ServicePak.  This requires
  you to have at least 5 megabytes of free disk space
  prior to creating the maintenance system created by
  SEMAINT.

  If you have a maintenance system installed with the
  OS/2 2.1 version of SEMAINT, you must re-install
  using SEMAINT from this version of the ServicePak.


                                          Page 18


  CID AND NVDM/2 NOTES
  ____________________

  For LCU and NVDM/2 users, you must unpack SEMAINT.EXE
  from the CID tree where OS/2 for Windows ServicePak
  resides, to the CID Code Server, directory ?:\EXE\OS2V21.

  When invoking SEMAINT.EXE supplied with OS/2 for Windows
  ServicePak the following rules apply to your
  installation procedures:

  1.  FSERVICE.EXE corresponds to the ServicePak for the
      product you are installing.  Therefore, you must
      make sure your installation procedures access the
      corresponding version of FSERVICE in the
      appropriate ServicePak Install tree.
  2.  When invoking FSERVICE.EXE for OS/2 for Windows
      ServicePak, you must specify the new "/CID"
      parameter.  This new parameter only applies to
      installations that have had SEMAINT installed.
      This new parameter is not needed when the client
      system is started by diskette.
  3.  Installation of the OS/2 for Windows ServicePak
      requires the specification of the "/S2:<CSDpath>"
      during the invocation of SEMAINT.EXE.
  4.  Installation of any ServicePak in your procedures
      FOLLOWING the installation of OS/2 for Windows
      ServicePak requires that the "/S2:<CSDpath>"
      parameter be specified during the invocation of
      SEMAINT.EXE.
  5.  Installation of any ServicePak in your procedures
      PRIOR to the installation of OS/2 for Windows
      ServicePak requires that the "/S2:<CSDpath>"
      parameter be omitted during the invocation of
      SEMAINT.EXE.

  INSTALLING OS/2 FOR WINDOWS SERVICEPAK USING RIPL
  _________________________________________________

  When installing OS/2 for Windows ServicePak using the
  IBM LAN Server 2.0 and 3.0 Remote Installation
  Program Load (RIPL), the OS/2 for Windows ServicePak
  RIPLINST.EXE program is dependent upon the OS/2 for
  Windows ServicePak UNPACK.EXE file.  Therefore, if
  you are using the OS/2 for Windows ServicePak
  RIPLINST.EXE program 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:


                                          Page 22


  1.  Insert OS/2 for Windows ServicePak 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 OS/2 for Windows ServicePak
      RIPLINST.EXE program.

                      SUPPORT
                      _______

  This ServicePak updates the display driver files that
  came with your original OS/2 for Windows product
  package.  (Such as the BVHVGA.DLL, BVHSVGA.DLL,
  VGA.SYS, and VSVGA.SYS.)

  If you install display drivers that replace these
  files after you have installed the ServicePak, the
  updates applied might be removed.


  DPMS-SUPPORTED DISPLAYS
  _______________________

  The XGA DMQS (\xga$dmqs\*.dqs) files in this version
  of the operating system do not have DPMS (Display
  Power Management Signaling) enabled for the DPMS
  supported displays.  You must use the DPMS OVERRIDE
  parameter provided with the Power Management Utility
  that is located in System Setup.

  GENERAL DISPLAY ADAPTER SUPPORT
  _______________________________


  INSTALLATION OF SPECIFIC VIDEO ADAPTERS

  o   ATI Graphics Pro Display Adapter

      In the "OS/2 2.1 Installation Guide",
      instructions are given for configuring the ATI**
      Graphics Ultra Pro.  These instructions state
      that the display 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.
  o   Radius XGA Display Adapter

      The Radius XGA display adapter is supported on
      PS/2* Models 35 and 40 and PS/ValuePoint* 486
      systems.  If you are using this 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.
  o   Sigma Legend Display Adapter

      OS/2 for Windows ServicePak 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.


                                          Page 25


  INSTALLING HIGH-RESOLUTION AND COLOR
  ____________________________________

  If you want to install a display driver that is
  higher than 640 x 480 x 16 and you obtained it
  from a source other than this ServicePak, then
  use the installation procedures provided in the
  README file that comes with the display driver.

  NOTE:  The following information pertains to video
         support.  If you want to change your video
         mode you must use the Selective Install
         program located in the System Setup folder.
         Do not use DSPINSTL.EXE to change your video
         support.

         After using Selective Install for VGA, you
         must delete the SVGADATA.PMI file located
         in the OS2 directory before you shut down
         your system.

  NOTES:

  1.  You can reinstall the S3 16-bit display driver
      for the 801, 805, and 928 chip sets.  There are
      several versions of OS/2 drivers (available on
      electronic services and from other vendors)
      supporting the 90C801, 90C805, and 90C928 chip
      sets from the S3 Corporation.  IBM provides
      service for the S3 32-bit display driver and
      recommends that you install the new version of
      this driver included in OS/2 for Windows ServicePak.
      This 32-bit display driver better utilizes the S3
      chip sets.

      IBM recommends that you DO NOT reinstall the
      S3-supplied 16-bit driver, the STB-supplied S3
      driver, or the IBM-supplied S3-16M driver.
      For information about installing S3 video display
      drivers see the "S3 Driver Installation" section
      in this file.

  2.  You can reinstall the Trident-supplied 16-bit
      display driver, but the OS/2 for Windows
      ServicePak SVGA 32-bit display driver better
      utilizes the Trident 8900C cards.  IBM provides
      service for the OS/2 2.1 ServicePak SVGA 32-bit
      display driver and recommends that you install
      the new version of this driver.

      IBM recommends that you DO NOT reinstall the
      Trident driver supplied on numerous bulletin
      boards, because it removes fixes from the Base
      Video Handler and Virtual Device Driver for the
      OS/2 VGA driver.


                                          Page 28


      To install the OS/2 for Windows ServicePak SVGA
      32-bit display driver, follow these steps:

      2.  Open the System Setup folder.
      3.  Open the Selective Install object.
      4.  Select the items you want to install.
      5.  Select OK and choose drive A as the source drive.
      6.  When prompted to insert the OS/2 diskettes,
          insert the OS/2 for Windows Installation
          diskettes.  (The ServicePak might need to be reapplied
          to ensure your system is at the proper level.)
      7.  When you see the Primary Display Adapter Type
          window, select Trident 8900C.
      8.  Follow the instructions for the Monitor
          Configuration/Selection Utility.  For more
          information on when to use this utility to
          set the refresh rate, see the "OS/2 2.1
          Installation Guide," Appendix A.

  3.  After you install the OS/2 for Windows
      ServicePak, install the Weitek display driver by
      following the instructions provided in the Weitek
      README file.  IBM testing indicates that the
      Weitek display driver runs successfully on

  Following is an explanation of the line that is
  executed in the LCU command file:

    C:\OS2\INSTALL\DSPINSTL /PK:SVGA /SK:NONE /S:X:\ /T: /MC:8

     /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: where C: is the drive where OS/2 for Windows ServicePak
         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
         640 x 480 x 256.
