        8.  Set the Enabled Disconnect setting to
            YES.
        9.  Set the IRQ setting to 11 (default is
            2).

    o   Are you installing OS/2 2.1 on an IBM(*)
        ThinkPad(*) with 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 by
            following the documentation that came
            with the ThinkPad.
        3.  Make a copy of the Installation
            Diskette.
        4.  Remove the copy and insert the
            original Installation Diskette into
            drive A.

                  A:\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.
            In the next two steps, you will be
            prompted to insert diskettes into both
            drive A and drive B.

            If your computer has only one diskette
            drive, when you are asked to insert a
            diskette into drive A, insert the
            Reference Diskette into your diskette
            drive.  When you are asked to insert a
            diskette into drive B, insert the copy

    question "Is your display adapter an ATI(**)
    Graphics Ultra(**) Pro?":

    Note:  If you have a Gateway 2000(**) system,
           refer to "Black Lines on an OS/2 Logo
           Screen" for further instructions.

>   On page xvii, add the following header before
    the third paragraph:

    SCSI-Based CD-ROM Support

>   On page xvii, add the following section to the
    end of the page:

    Non-SCSI CD-ROM Support for Sony, Panasonic,
    and Mitsumi

    For the Sony(**), Panasonic(**), and
    Mitsumi(**) non-SCSI drives to be recognized
    by OS/2, the base port address specified on
    the CD-ROM BASEDEV statement in CONFIG.SYS
    must match the base I/O port address specified
    on the CD-ROM host adapter card.

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

    Modifying CONFIG.SYS for the Sony CDU-31A
    Device Driver:

    The examples that follow illustrate how this
    CD-ROM is attached to the most common host
    adapters and indicate the required parameter
    switch settings for each CD-ROM drive.

    Example 1:  The Sony CDU-31A CD-ROM drive is
    attached to a 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 host adapter is set to its
    default port address of 340h, the CONFIG.SYS
    statement 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 must 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 the CONFIG.SYS file should appear as
    follows:

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

    Example 2:  The Sony CDU-31A CD-ROM drive is
    attached to a Media Vision(**) ProAudio
    Spectrum(**) 16 host adapter.

    In this case, the line in CONFIG.SYS must be
    modified and should appear as follows:

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

    Example 3:  The Sony CDU-31A CD-ROM drive is
    attached to a 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 these
    adapter cards.  For example, if the Sound
    Blaster card is set for a base I/O port
    address of 220h, the line in CONFIG.SYS should
    appear as follows:

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

    Modifying CONFIG.SYS for the Panasonic Device
    Driver:

    The Panasonic device driver (SBCD2.ADD)
    supports the following CD-ROM drives:

    -   Panasonic CR-521,522,523,562,563
    -   Creative Labs OmniCD
    -   IBM ISA CD-ROM drive

    The examples that follow illustrate how this
    CD-ROM is attached to the most common host
    adapters and indicate the required parameter
    switch settings for each CD-ROM drive.

    Example 1:  A Panasonic, Creative Labs OmniCD
    or IBM ISA CD-ROM drive is attached to a
    standard Panasonic or IBM CD-ROM host adapter.

    The standard Panasonic or IBM host adapter
    supports base I/O port addresses of 300h,
    310h, 320h or 330h.  For example, if the
    adapter is set to a base I/O port address of
    300, the line in the CONFIG.SYS file should
    appear as follows:

          BASEDEV=SBCD2.ADD /P:300

    Example 2:  A Panasonic, Creative Labs OmniCD
    or IBM ISA CD-ROM drive is attached to a
    Creative Labs Sound Blaster Pro, Sound Blaster
    16, or Sound Blaster 16 MultiCD.

    If the Sound Blaster card is set for a base
    I/O address of 220h, the line in CONFIG.SYS
    should appear as follows:

          BASEDEV=SBCD2.ADD /P:220

    Example 3:  A Creative Labs OmniCD is attached
    to a standard Creative Labs CD-ROM host
    adapter.

    The standard Creative Labs host adapter
    supports base I/O port addresses of 250h or
    260h.  For example, if the adapter is set to a
    base I/O port address of 250, the line in the
    CONFIG.SYS file should appear as follows:

          BASEDEV=SBCD2.ADD /P:250 /T:2

    Modifying CONFIG.SYS for the Mitsumi CD-ROM
    Device Driver:

    The examples that follow illustrate how this
    CD-ROM is attached to the most common host
    adapters and indicate the required parameter
    switch settings for each CD-ROM drive.

    Example 1:  A Mitsumi CD-ROM drive is attached
    to a Mitsumi host adapter.

    The Mitsumi host adapter supports I/O port
    address ranges from 300h to 3FCh.  If the
    Mitsumi host adapter is set to a base I/O port
    address of either 300h or 340h, 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
    the CONFIG.SYS file should appear as follows:

          BASEDEV=MITFX001.ADD /P:320

    Example 2:  A Mitsumi CD-ROM drive is attached
    to a Creative Labs Sound Blaster 16 MultiCD.

    If the Mitsumi CD-ROM port on the Sound
    Blaster 16 MultiCD is set to an I/O port
    address of 320, the line in CONFIG.SYS should
    appear as follows:

          BASEDEV=MITFX001.ADD /P:320

>   On page xviii, add the following note before
    the second paragraph:

    Note:  Use the LOADDSKF utility program to
           create diskette images, which are
           compressed, binary images of a
           diskette.  The LOADDSKF.EXE is in the
           \DISKIMGS directory of the CD.
           LOADDSKF can be run from either the DOS
           or OS/2 operating system.

>   On page xix, add the following additional note
    to the section titled "Additional Notes for
    Users of OS/2":

    o   To avoid desktop problems such as a blank
        desktop or duplicated icons, you need to
        run CHKDSK /F and have at least 20MB of
        free space in your OS/2 partition.


CHAPTER 1.  CHOOSING AN INSTALLATION PROCEDURE
______________________________________________

>   On page 6, replace paragraph 3 with the
    following:

    The amount of space you need for the OS/2 2.1
    partition depends upon which features of the
    operating system you are going to install.
    The amount of space required is also related
    to how much system memory your computer has
    and how many applications will be running at
    the same time.

    If you are going to install all features of
    the operating system, you need approximately
    40MB of free disk space and a minimum of 10MB
    of space for the SWAPPER.DAT file.

    If you are going to install selected features,
    you need from 20MB to 40MB.  These
    installation choices are described in more
    detail in Chapter 2, "Installing OS/2 2.1 as
    the Only Operating System (Basic
    Installation)".

    If you are going to install multimedia
    support, you need up to an additional 5MB of
    hard disk space.


CHAPTER 2.  INSTALLING OS/2 2.1 AS THE ONLY
___________________________________________
OPERATING SYSTEM (BASIC INSTALLATION)
_____________________________________

>   On page 16, replace the first 3 paragraphs
    with the following:

    Install preselected features If you select
                                this predetermined
                                set of OS/2
                                features, you will
                                need approximately
                                32MB of total disk
                                space for the
                                operating system
                                and its features
                                and a minimum of
                                10MB for the
                                swapper file.

    Install all features        If you select all
                                features, you will
                                need approximately
                                40MB of total disk
                                space for the
                                operating system
                                and its features

                                10MB for the
                                swapper file.

>   On page 24, add the following paragraph before
    the sentence "To make a selection different
    from the one listed in this window...":

    For non-SCSI CD-ROM drives, if you cannot
    access your CD-ROM device after installation,
    ensure that the port address in the BASEDEV
    statement in the CONFIG.SYS file on your
    startup partition (hard drive) matches the
    port address on the CD-ROM host adapter card.
    See "Non-SCSI CD-ROM Support for Sony,
    Panasonic, and Mitsumi".

>   On page 33, replace the second paragraph of
    the second list entry with the following:

    When the Update Windows desktop when WIN-OS/2
    desktop is modified option is selected during
    the installation, the WIN-OS/2(*) PROGMAN.INI
    file points to the Microsoft(**) Windows(**)
    group files.  However, WIN-OS/2 does not use
    the Microsoft Windows PROGMAN.INI file.  Two
    different PROGMAN.INI files exist and each one
    is maintained by the respective system (OS/2
    or Windows).

    Because both desktops share group files, they
    will reflect the changes when an existing
    group of files is modified.  However, if a
    modification to the PROGMAN.INI file is
    necessary (add/remove a group file), the
    desktops will differ.  New groups will not be
    reflected on the Microsoft Windows desktop.

    the first paragraph:

    Warning:  While it is possible to install OS/2
    2.1 and DOS in the same partition, you might
    experience problems during the installation.
    To avoid these problems, use Boot Manager
    instead of Dual Boot.  Refer to Chapter 4,

>   On page 83, add the following section before
    the section titled "Bypassing the Boot Manager
    Menu":

    Installing the Upgraded Version of MS-DOS 6.x

    If you are running a Dual Boot or Boot Manager
    configuration and you want to install the
    upgraded version of MS-DOS(**) 6.x, do the
    following:

    1.  Start your system with a current version
        of MS-DOS using a bootable MS-DOS
        diskette; do not use a Dual Boot or Boot
        Manager session.

    2.  Prepare an Uninstall Diskette so you can
        restore your previous version of DOS if
        needed.  (Refer to your MS-DOS
        documentation for instructions.)

    3.  Edit the CONFIG.SYS and AUTOEXEC.BAT
        files.

        a.  Type REM before each command line that
            starts a disk-caching,
            delete-protection, or antivirus
            program.

            Note:  You need to disable the startup
                   command for the MS-DOS
                   SMARTDrive program.

        b.  Disable any automatic message service,
            such as a network pop-up or a printing
            notification that is displayed on your
            screen.

        c.  Save your changes to the CONFIG.SYS
            and AUTOEXEC.BAT files.

        d.  Restart your system with the current
            installed version of MS-DOS, but not
            from a Dual Boot or Boot Manager
            session.

    4.  Insert the MS-DOS 6.x SETUP Diskette 1
        into drive A.

    5.  At the DOS command prompt, type:

              A:SETUP

    6.  If your system is setup to use OS/2 Boot
        Manager, you will receive a message that
        states "This partition will not be
        available when using MS-DOS 6.x."  Ignore
        this message and choose Continue Setup.

        If your system is setup to use OS/2 Dual
        Boot, you will receive a message prompting
        you to remove the non-MS-DOS operating
        system files from the drive.  Ignore this
        message and choose Do Not Remove the
        Files.  You will also receive a message
        stating "The operating system on the drive
        may be disabled."  Ignore this message and
        choose Continue Setup.

    7.  Follow the instructions on your screen.
        If you need help during any of these
        procedures, press F1 for Help.

    8.  When you are prompted to do so, insert the
        diskette created in step 2 into drive A.

    9.  Restart your system when you have
        completed the Setup program.  The system
        should start in MS-DOS 6.x.

        Warning:  The MS-DOS 6.x installation
        program suggests that you run the
        MS-DEFRAG and MS(**) DOUBLE SPACE utility
        programs.  These utility programs are not
        compatible with the OS/2 environment, and
        might cause data loss in OS/2 if executed.
        Other MS utility programs that perform
        direct diskette I/O, such as Interlink and
        UNDELETE, could compromise the OS/2 file
        system and are not supported.

    10. To make the OS/2 system partition active
        again:

        o   If your system is setup to use OS/2
            Boot Manager, do the following:

            a.  Type FDISK at the command prompt.
            b.  When the FDISK screen appears,
                choose option 2; then press Enter.
            c.  Choose the number that corresponds
                with the Boot Manager partition;
                then press Enter.
            d.  When the confirmation screen
                appears, press Esc.
            e.  Press Esc again to exit FDISK.
            f.  Restart your system.

        o   If your system is setup to use OS/2
            Dual Boot, copy the COMMAND.COM file
            from the \DOS directory to the root
            directory.

    Note:  SETUP places your previous DOS files in
           a directory named OLD_DOS.x.  If you
           are sure you do not want to restore
           your previous version of DOS, you can
           delete the directory and its contents
           by typing DELOLDOS at the command
           prompt.


CHAPTER 5.  USING A RESPONSE FILE TO INSTALL
____________________________________________

>   On page 87, replace the instructions after the
    first paragraph with the following:

    This procedure requires unpacking compressed
    files.  To do this, copy the UNPACK2.EXE file
    from Diskette 2 to your hard drive.  Any
    unpack instructions should be performed from
    this hard drive.

    1.  Make a copy of Diskette 1.  You will
        modify only this copy.

    2.  Make extra room on the copy of Diskette 1
        by deleting the following files, which
        will not be needed in a response file
        installation:

        a.  Delete the MOUSE.SYS, SYSINST2.EXE,
            and BUNDLE files from the copy of
            Diskette 1.

            Note:  Deleting the BUNDLE file is not
                   necessary for CD-ROM
                   installation.

        b.  If you are installing OS/2 2.1 on a
            Micro Channel(*) computer, delete the
            IBM1*.ADD file from the copy of
            Diskette 1.

        c.  If you are installing OS/2 2.1 on a
            non-Micro-Channel computer, delete the
            IBM2*.ADD and *0S.SYS files from the
            copy of Diskette 1.

    3.  Edit the CONFIG.SYS file on the copy of
        Diskette 1:

        a.  Change the SET OS2_SHELL statement
            from "SET OS2_SHELL=SYSINST2.EXE" to
            the following:

                  SET OS2_SHELL=RSPINST.EXE A:\OS2SE20.RSP

        b.  Delete the following statement:

                  DEVICE=MOUSE.SYS

        c.  If you are installing OS/2 2.1 on a
            Micro Channel computer, delete the
            following statements in the CONFIG.SYS
            file on the copy of Diskette 1:

                  BASEDEV=IBM1FLPY.ADD
                  BASEDEV=IBM1S506.ADD

        d.  If you are installing OS/2 2.1 on a
            non-Micro-Channel computer, delete the
            following statements in the CONFIG.SYS
            file on the copy of Diskette 1:

                  BASEDEV=IBM2FLPY.ADD
                  BASEDEV=IBM2ADSK.ADD
                  BASEDEV=IBM2SCSI.ADD

    4.  Use the following statement to unpack the
        compressed file REQUIRED that is located
        on Diskette 11 and copy the SAMPLE.RSP
        file contained within it to the root
        directory of your hard drive:

              UNPACK2 A:\REQUIRED C:\ /N:SAMPLE.RSP

        a.  Use an editor (such as the System
            Editor) to modify and save the file.
            The file contains comments that
            explain each of the installation
            options.

        b.  Copy this modified response file to
            the copy you made of Diskette 1 and
            rename it OS2SE21.RSP.  For example:

                  COPY C:\SAMPLE.RSP A:\OS2SE21.RSP

    5.  Use the following statement to unpack the
        compressed file REQUIRED that is located
        on Diskette 7 and copy the RSPINST.EXE
        file contained within it to the root
        directory of your hard drive:

              UNPACK2 A:\REQUIRED C:\ /N:RSPINST.EXE

    6.  Copy the RSPINST.EXE file to the copy of
        Diskette 1.

    7.  If you have a Micro Channel computer and
        the Reference Diskette contains ABIOS.SYS
        and *.BIO files, you will also need to
        modify the Installation Diskette:

        a.  Make a copy of the OS/2 2.1
            Installation Diskette.

        b.  Delete the *.BIO and ABIOS.SYS files
            from the copy of the Installation
            Diskette.

        c.  Copy the *.BIO and ABIOS.SYS files
            from the Reference Diskette to the
            copy of the Installation Diskette.

            Note:  This Installation Diskette copy
                   is now system-specific.  You
                   will need to create a modified
                   Installation Diskette for each
                   type of system on which you are
                   installing OS/2 2.1.

        d.  Use this copy of the diskette during
            the installation process.

    8.  Begin the installation of the workstation
        by inserting the copy of the Installation
        Diskette and restarting the system.

    9.  When prompted for Diskette 1, insert the
        modified copy of Diskette 1 and press
        Enter.

        From this point, the installation program
        will prompt only for the insertion of
        diskettes.  No other installation actions
        are necessary.

    10. When prompted to insert Diskette 1 again,
        insert the original copy of Diskette 1
        into drive A.

    Note:  If you are installing from diskettes,
           you will be prompted to insert the
           Installation Diskette after the display
           driver diskettes; insert Diskette 1
           instead.

    Response files can be used to install the same
    set of options on multiple workstations.  You
    must ensure that the workstations are set up
    with the same set of options and hardware.

>   On page 88, add the following after the first
    paragraph under the section titled "Installing
    OS/2 2.1 from a Local Area Network Source":

    Requirements for remote installation of OS/2:

    o   The RAM requirements vary from 6MB to 10MB
        or more, depending on the installation
        variables.

        --  Redirected remote installation
            requires more RAM than disk
            installation because the SWAPPER.DAT
            file is not active.

        --  If you are doing a redirected remote
            installation without CID, you only
            need about 6MB of RAM.

        --  When using CID, the RAM requirements
            usually range from 6MB to 8MB.

        --  If you are using a process on top of
            CID, like NVDM/2, 8MB to 10MB (or
            more) might be required.  The main
            variable with CID is the size of the
            REXX procedure and which dynamic link
            libraries it pulls in.  With remote
            installation, the LAN connection
            utility programs are the main
            variables.  The version of OS/2 that
            you are installing is another
            variable.

        --  The reduced diskette version of OS/2
            2.1 (20 diskettes) requires more RAM
            because of the new UNPACK2.EXE
            routine.

    o   During remote installation, the
        SWAPPER.DAT file is not active because the
        disk partition containing the active
        swapper file cannot be formatted during
        installation.  The SWAPPER.DAT file can be
        made active, but the disk partition has to
        be a local partition and preformatted.  In
        order to activate the SWAPPER.DAT file,
        the CONFIG.SYS file has to be edited.  To
        do this, replace the existing
        MEMMAN=NOSWAP statement with the
        following:

              MEMMAN=SWAP,PROTECT

              SWAPPATH=D:\ 2048 4096

    o   Personal Computers might require more RAM
        as the network drivers might have to store
        more data into the RAM buffers until the
        processor is able to handle the data.

           used for Selective Install.  There are
           two levels of diskettes, compressed and
           uncompressed.  These diskettes are
           identical except for the purpose of
           Selective Install.  The compressed
           diskettes have salmon-colored labels,
           and the uncompressed diskettes have
           blue-colored labels.

>   On page 114, add the following note after the
    heading titled "Installing Display Drivers
    Using Display Install":

    Note:  If you want to install display drivers
           using Display Install, you must have
           OS/2 DOS Support installed.


APPENDIX B.  DIAGNOSING SYSTEM PROBLEMS
_______________________________________

>   On page 117, replace the first list entry with
    the following:

    o   Single inline memory modules conflicts

        You might encounter problems if the single
        inline memory modules of your computer
        system were produced by different
        manufacturers, are of different classes,
        or operate at different speeds.  Refer to
        the TRAP0002 message for more information.

>   On page 118, add the following after the last
    list entry:

    o   Disk Read Error

        Systems with a HYPERACE(**) 486 Upgrade
        might receive a "Disk Read Error" when
        trying to read Diskette 1 during
        installation.  Several switches on the
        HYPERACE card might need to be disabled:

        1.  Switch 1 - disables the main cache.
        2.  Switch 2 - disables the HIMEM cache.
        3.  Switch 4 - disables the BIOS cache.

        After installation, reset the switches to
        enable the caches.

        For more information on the procedures,
        check the HYPERACE card documentation.

>   On page 119, replace the line "Messages
    beginning with "TRAP"" with the following:

    Messages beginning with "TRAP0002"

>   On page 121, add the following messages:


    +--------------------------------------------+
    |                                            |
    | An error occurred when System Installation |
    | tried to locate the KBD01.SYS file.        |
    |                                            |
    +--------------------------------------------+

      Explanation:  The installation program could
      not locate the KBD01.SYS file on a system
      with a Micropolis(**) SCSI hard drive.  This
      file is not located in the default path or
      the path specified in the CONFIG.SYS file.

      Action:

      (1) Edit the CONFIG.SYS file and add the
      following statement:

            DEVICE=KBD01.SYS

      (2) Disable the "Read ahead cache" in the
      UTIL.EXE.

    +--------------------------------------------+
    |                                            |
    | An error occurred when System Installation |
    | tried to load the dynamic link library.    |
    |                                            |
    +--------------------------------------------+

      Explanation:  The installation program could
      not load the dynamic link library because
      there is not enough random access memory
      (RAM).

      Action:  Add more system memory (RAM).

      o   Future Domain TMC-1660/1670/1680 with
          BIOS revision level 2.0.

>   On page 122, replace the COUNTRY.SYS message
    with the following:


    +--------------------------------------------+
    |                                            |
    | COUNTRY.SYS file cannot be found           |
    |                                            |
    +--------------------------------------------+

      Explanation:  The OS/2 operating system does
      not recognize the hard disk or diskette.

      (1) If you have a PS/2(*) P70, you need to
      request an engineering change.

      (2) A diskette drive or a hard disk drive
      controller might have an additional device
      (such as a tape backup) attached to it.

      (3) The diskette drive or hard disk drive
      controller might not reside at its own
      interrupt request (IRQ) level.

      (4) The hard disk partition on which you are
      installing OS/2 2.1 was compressed with a
      DOS data compression program.

      (5) If you have a Gateway(**) Nomad(**)
      laptop computer with Phoenix(**) BIOS 1.02,
      you will have to update the BIOS to the next
      level.

      (6) If your system is using an AMI(**) Fast
      Disk or a Fast Disk II SCSI adapter, they
      will be recognized as Adaptec adapters.

      (7) You have more than two (2) hard drives
      in the system.

      Action:

      (1) Contact your IBM customer engineer or
      computer dealer and request the engineering
      change announcement "ECA068."

      (2) Disconnect the device, if possible.

      (3) Refer to the operations manual that came
      with your computer for information about the
      IRQ setting.  (Refer to OS/2 2.1 Using the
      Operating System for more information about
      setting IRQ levels.)

      (4) Use the data compression program to
      decompress the partition, and then retry the
      installation.

      (5) Update your Gateway Nomad Laptop
      computer with Phoenix BIOS 1.03 or later.

      (6) After installation, edit the CONFIG.SYS
      file as follows:

      o   Delete any line with the following:

               BASEDEV=AHA1xxx.ADD

          where xxx can be any character.

      o   Ensure that the statement
          BASEDEV=IBMINT13.I13 is included.

      (7) Check the partitions on any drives
      beyond the first two drives.  If they are
      primary partitions, back up the data and
      re-partition them as logical drives.

>   On page 123, replace the TRAPxxx message with
    the following:


    +--------------------------------------------+
    |                                            |
    | TRAPxxx                                    |
    |                                            |
    +--------------------------------------------+

      Explanation:  In general, traps are symptoms
      of software-related problems.  After you
      have pursued these symptoms from a software
      failure perspective, you should consider the
      potential of a hardware cause relating to
      caches and memory.

      (1) If your computer has an 80486
      microprocessor, your computer might require
      faster RAM chips (60ns or 70ns).

      (2) There might be a problem with the
      external (level 2) CPU memory cache or main
      memory system on ISA or EISA systems.

      Action:

      (1) From the setup/diagnostics diskette or
      the BIOS Setup program built into the
      computer, try disabling all shadow RAM and
      external (level 2) CPU memory cache.

      (2) If problems persist during the
      installation of OS/2 after performing the
      above action, turn off the turbo switch (if
      one is available) on your system and retry
      the operation.  Disable caching during
      installation or turn the turbo switch off.

>   On page 123, add the following messages:


    +--------------------------------------------+
    |                                            |
    | TRAP0002                                   |
    |                                            |
    +--------------------------------------------+

      Explanation:  A TRAP0002 error can be a
      memory parity error on the system board or
      on an adapter card.

      (1) Your computer system might have single
      inline memory modules that were produced by
      different manufacturers or that operate at
      different speeds.  Or, your computer system
      might have different classes of single
      inline memory modules.  (For example, a 1x9
      module cannot be used with a 1x3 module.)

      Action:

      (1) Remove any defective single inline
      memory module.  It might also be necessary
      to replace one or more modules.

      (2) If your IBM computer is a 33 MHz and the
      microprocessor card part number is 84F9356,
      contact your local IBM representative and
      request an ECA053.

      (3) If the Memory Riser card part number is
      N33F4905 or 84F9356 on an IBM Model 8590
      system, contact your local IBM
      representative and request an ECA084.

      Explanation:  When trying to do a redirected
      remote installation of OS/2 2.1 using
      SYSINST2 for panel installation, the error
      message SYS0005 appears while attempting to
      copy UNPACK.EXE.

      Action:  This Access Denied Error is caused
      by damage to the extended attribute data on
      the NetWare(**) Server.  To correct this
      problem, delete the old disk images on the
      server and create new OS/2 disk images.

>   On page 124, add the following message:

      Explanation:  The file IBM386FS\HPFS386.IFS
      does not contain a valid device driver or
      file system driver.

      Action:  Edit your CONFIG.SYS file and
      delete the following line:

           IFS=x:\OS2\HPFS.IFS

>   On page 124, replace the SYS2025 message with
    the following:


    +--------------------------------------------+
    |                                            |
    | SYS2025                                    |

    +--------------------------------------------+

      Explanation:  A disk read error occurred.
      This might be a disk error or a damaged
      system boot record.

      Action:

      (1) If this error occurred while the system
      was loading, follow the procedure under
      "Recovering from Errors on the Hard Disk".

      (2) If this error occurred when the system
      was reading the installation diskettes,
      there might be an error on the diskette.  If
      you already have an operating system
      installed on your computer, use the DISKCOPY
      command to make a copy of the installation
      diskettes.  Retry the installation with the
      newly copied diskettes.

      (3) If your computer has BIOS supplied by
      AMI or Phoenix, you might need to upgrade
      the BIOS.  Refer to Appendix G.

      (4) If your system has a local bus IDE
      controller card, disable the BIOS on the
      32-bit local bus IDE controller card and use
      the generic INT13 driver instead of
      IBM1S506.ADD.

      (5) Make sure that there is not a hardware
      problem with your hard disk controller or
      your diskette drive.

>   On page 125, replace the SYS2026 message with
    the following:


    +--------------------------------------------+
    |                                            |

    +--------------------------------------------+

      Explanation:  The file OS2LDR cannot be
      found.  This is a hidden system file and
      must reside in the root directory of the
      drive from which the operating system is
      started.

      Action:

      (1) Make sure a non-system diskette is not
      in the diskette drive.  If necessary, remove
      the non-system diskette and restart the
      system.

      (2) If the OS2LDR file is missing from the
      hard disk, start up the system using the
      Installation Diskette.  Insert Diskette 1
      and press Enter.

      (3) Copy the OS2LDR file from the
      Installation Diskette to the OS/2 partition.

>   On page 127, add the following after the
    paragraph under the heading titled Diskette 1:

    If you are installing on a system with an
    Allways(**) IN2000 SCSI adapter, an IPE or
    FDISK error is displayed during the
    installation of Diskette 1.  Upgrade your
    system to the current BIOS level of VCN:1-02.
    The Allways IN2000 SCSI adapter might require
    an EPROM upgrade to operate with OS/2 2.1.
    You might find that you have some problems
    when trying to install over DOS partitions.
    To correct these problems, you need to install
    the EPROMS and reformat the hard drive.

    If you are installing OS/2 2.1 on a MYLEX
    system, a TRAP0008 error occurs during the
    installation of Diskette 1.  For more
    information on this error, contact MYLEX.

    If you are installing on a Compaq(**) 386/331
    Deskpro system, a TRAP000D error occurs during
    the installation of Diskette 1.  To correct
    this problem, do the following:

    1.  Make a copy of Diskette 1.  You will
        modify the copy.
    2.  Use an editor to edit the CONFIG.SYS file
        that exists on the copy of Diskette 1.
    3.  Delete the following statements:

              BASEDEV=IBM2M57.ADD
              BASEDEV=IBM2SCSI.ADD

    4.  Use the copy of the diskette during the
        installation process instead of the
        original.

>   On page 127, add the following list entry
    after Diskette 3:

    o   Diskette 6

        If the system refuses Diskette 6 and makes
        a beeping sound, your system might be
        infected with the Joshi virus.  The Joshi
        virus is a DOS virus that interferes with
        OS/2 and seems to cause random lockups.
        The Joshi virus:

        --  Operates by trapping disk reads and
            writes.  If the virus is active in
            memory, programs that try to locate
            the virus on diskette will have
            problems detecting it.

        --  Is carried on the boot sector of an
            infected data diskette or system
            diskette.  This virus originated in
            DOS but can survive in OS/2.  When you
            start an infected system, the virus
            resides in memory and survives a
            Ctrl+Alt+Del startup.  If the user
            does not type in the text "Happy
            Birthday Joshi", the system will stop.

        --  Is copied to the boot sector of every
            diskette.  The virus will be
            transferred to any computer on which
            the user performed any diskette
            operation that included reading from,
            or writing to, the infected diskette.

        --  Spreads from infected diskettes to DOS
            and OS/2 systems when the systems are
            started from diskettes.

        --  Interferes with the startup from the
            hard disk of OS/2-based systems.  The
            warning that OS/2 will give is that
            the IBM1FLPY.ADD file is bad or
            missing.

        Many antivirus packages are effective at
        detecting this virus.  In DOS, The Norton
        Antivirus(**) Version 2.1 can both detect
        and clear the virus.  The Joshi virus can
        also be cleared from DOS-based systems
        with the undocumented FDISK parameter MBR.
        However, the FDISK.EXE must be copied to
        and run from each partition.  Type the
        following:

              FDISK /MBR

        This procedure causes the master boot
        record to be refreshed by the system, and
        the Joshi virus is overwritten.  However,
        this procedure does not remove the virus
        from memory.  The system needs to be
        restarted and rescanned for the virus.

        In OS/2, Central Point(**) Antivirus can
        detect the virus.  McAfee(**) Clean and
        Scan can both detect and clear the virus.
        For more information on this antivirus
        program, contact McAfee Associates at
        (408) 988-3832.

    the page:

    Installation on a Quantum II XL Hard Card

    If you have a Quantum(**) hard card, you must
    make a modification to the
    BASEDEV=IBM1S506.ADD line in the CONFIG.SYS
    file.  To modify the BASEDEV statement, do the
    following:

    1.  Edit the CONFIG.SYS file on Diskette 1.
    2.  Change the BASEDEV statement to:

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

    3.  Save the CONFIG.SYS file.
    4.  Install OS/2 2.1.

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

    Black Lines on a OS/2 Logo Screen

    During the installation on a Gateway 2000 with
    an 80486/66MHz processor, a local bus, and an
    ATI Graphics Ultra Pro, the system will get to
    the screen with the colorful OS/2 full-screen
    symbol, and then the installation will stop.
    The display screen shows horizontal bands of
    video separated by black bands that scroll
    horizontally across the screen.  To correct
    this problem, do the following:

    1.  Start DOS.
    2.  Change the OS/2 directory to MACH32.
    3.  Type:

              INSTALL

    4.  At the Main Selection screen select Set
        Power up Configuration.
    5.  Select Monitor Type, and press Enter.
    6.  Select 1572 Monitor with 72Hz Refresh
        Rate, and press Enter.
    7.  Select IBM Default as the new display.

    Note:  After OS/2 is successfully installed,
           repeat the steps to reselect the 1572
           Monitor type.

    White Screen Appears during Installation

    If the display screen is white during the
    installation of OS/2 2.1 and there is no
    system activity, set the video adapter to
    operate on an 8-bit mode and move the adapter
    to an 8-bit slot.  Do the following:

    1.  Turn off the system and disable the
        autosensing capability of the video
        adapter.
    2.  To modify the settings, refer to the
        documentation that came with your video
        adapter.
    3.  Place the adapter in an 8-bit slot until
        you have successfully installed OS/2 2.1.
    4.  The adapter can be returned to the 16-bit
        slot and set back to the 16-bit mode.

>   On page 129, add the following after the
    section titled "Adding Support for a Mouse":

    System Unable to Access CD-ROM Drive

    If you clicked on the CD-ROM check box on the
    System Configuration screen during the
    installation of OS/2, the installation program
    put the entry None in the CD-ROM text box and
    the CD-ROM files were not copied.

    Because some drives are not directly supported
    by the device drivers shipped with the OS/2
    product, you must now select OTHER from the
    selection list to enable CD-ROM support.

    For Sony, Mitsumi, or Hitachi(**) users, if

        6.  If the problem continues, you must run
            the MAKEINI program.

    o   If you have moved program groups off the
        desktop and into a folder, you should move
        them back on the desktop before installing
        OS/2 2.1.  Otherwise, duplicate icons
        could appear on the screen.  If you try to
        delete these icons, the original icons
        will also be deleted.

    o   If you want to recover a backed up OS/2
        2.0 desktop, you can use the following
        procedure:

        1.  Insert the Installation Diskette, and
            turn on the computer.
        2.  Press Esc to get to the command

            hard disk.
        4.  Copy the backup INI files to the OS/2
            subdirectory.
        5.  Run the MAKEINI OS2.INI INI.RC
            program.
        6.  Run the MAKEINI OS2SYS.INI INISYS.RC
            program.
        7.  Delete the DESKTOP directory.
        8.  Restart the system.

        Notes:

        1.  If you try to recover the backed up
            OS/2 2.0 desktop, the customization
            for the OS/2 2.1 desktop will be lost.

        2.  The name of your DESKTOP directory
            might be slightly different.  To find
            the actual name of your DESKTOP
            directory currently in use, display
            the Settings notebook for the desktop
            and select the File page.  The current
            desktop name is shown under Physical

    Appendix H.  Creating an OS/2 Startup Diskette

    The following procedure explains how to create
    a startup diskette for OS/2 2.1.

    1.  Insert the Installation Diskette into
        drive A.

    2.  Copy the SYSINSTX.COM file to your OS/2
        directory.

    3.  Remove the Installation Diskette from
        drive A.

    4.  Insert Diskette 1 into drive A.

    5.  Copy the KEYBOARD.DCP and SYSINST1.EXE
        files to a subdirectory on your hard disk.

    6.  Use the ATTRIB command to display the
        OS2KRNL, OS2LDR, and OS2LDR.MSG files.

    7.  Remove Diskette 1 from drive A.

    8.  Insert a blank, formatted diskette into
        drive A and type:

              SYSINSTX A:

    9.  Copy the OS2KRNL, OS2LDR, and OS2LDR.MSG
        files to the startup diskette, and then
        use the ATTRIB command to hide the files.

    10. Copy the KEYBOARD.DCP and SYSINST1.EXE
        files from the subdirectory to the startup
        diskette.

    11. Copy the following libraries from the
        \OS2\DLL directory to the startup
        diskette:

        ANSICALL.DLL          DOSCALL1.DLL
        NLS.DLL               NPXEMLTR.DLL
        BKSCALLS.DLL          KBDCALLS.DLL
        OS2CHAR.DLL           BMSCALLS.DLL
        MOUCALLS.DLL          QUECALLS.DLL
        BVHINIT.DLL           MSG.DLL
        SESMGR.DLL            BVSCALLS.DLL
        NAMPIPES.DLL          VIOCALLS.DLL

    12. Copy the HARDERR.EXE and COUNTRY.SYS files
        from the \OS2\SYSTEM directory to the
        startup diskette.

    13. Copy the SYSLEVEL.OS2 file from the
        \OS2\INSTALL directory to the startup
        diskette.

    14. Copy the CMD.EXE, DOS.SYS, IBMINT13.I13,
        and OS2DASD.DMD to the startup diskette
        from the \OS2 directory.  If you are
        planning to use HPFS, you need to copy the
        HPFS.IFS file to the startup diskette.

    15. If you have an AT(*) system, copy the
        CLOCK01.SYS, KBD01.SYS, PRINT01.SYS,
        SCREEN01.SYS, and IBM1FLPY.ADD files to
        the startup diskette.

    16. If you have a Micro Channel PS/2 system,
        copy the CLOCK02.SYS, KBD02.SYS,
        PRINT02.SYS, SCREEN02.SYS, and
        IBM2FLPY.ADD files to the startup
        diskette.  The following command is used
        to copy the ABIOS.SYS file on the startup
        diskette for a PS/2 system:

              ECHO . > A:ABIOS.SYS

    17. If you have a SCSI hard drive, copy the
        IBM2SCSI.ADD file (or the .ADD file from
        the manufacturer).  If you have a hard
        drive other than a SCSI hard drive, copy
        the IBM1S506.ADD file to the startup
        diskette.

    18. Using an editor, create the following
        CONFIG.SYS file on the startup diskette
        (in this case, for HPFS):

          IFS=HPFS.IFS /CACHE:64
          BUFFERS=32
          IOPL=YES
          MEMMAN=NOSWAP
          PROTSHELL=SYSINST1.EXE
          SET OS2_SHELL=CMD.EXE
          DISKCACHE=64,LW
          PROTECTONLY=YES
          LIBPATH=.;\;
          PAUSEONERROR=NO
          CODEPAGE=850
          DEVINFO=KBD,US,KEYBOARD.DCP
          DEVICE=\DOS.SYS
          SET PATH=.;\
          SET DPATH=\;
          SET KEYS=ON
          BASEDEV=PRINT0x.SYS  (where x is 1 for AT; 2 for Micro Channel
          BASEDEV=IBMxFPLY.ADD (where x is 1 for AT; 2 for Micro Channel
          BASEDEV=IBMINT13.I13
          BASEDEV=OS2DASD.DMD

        a.  If you have a SCSI drive on a Micro
            Channel computer, add the following
            statement to this file:

                  BASEDEV=IBM2SCSI.ADD

        b.  If you have a hard drive other than a
            SCSI drive on a non-Micro Channel
            computer, add the following statement
            to this file:

                  BASEDEV=IBM1S506.ADD

        c.  If you have any space left on your
            diskette, copy the CHKDSK.COM file
            from the \OS2 directory to the startup
            diskette.

>   On page 68, add the following note to the end
    of the page:

    Note:  If the keyboard speed is set in
           WIN-OS/2, when that WIN-OS/2 session is
           started, the keyboard speed for the
           entire system is reset and remains
           reset even after that WIN-OS/2 session
           is closed.

>   Replace the Power section at the end of this
    chapter with the information that follows.


POWER


            The Power object manages and tracks power consumption in
            battery-powered computers that support the Advanced Power
            Management (APM) standard.  The APM standard defines the
            way the hardware and software work together to reduce
            power consumption and help extend battery life.

If your computer supports the APM standard, the
Power object might be automatically installed
during the OS/2 2.1 installation process.  If it
was not installed, you can install it by using
Selective Install and selecting Advanced Power
Management.  For information about Selective
Install, see "Selective Install".

Note:  This power management feature is not
       available if your computer does not have
       APM BIOS or a device driver that emulates
       APM BIOS.

OS/2 2.1 APM support relies on the power status
information returned from the BIOS on your
computer.  You might notice incorrect battery life
or status within the Power icon on your computer.
If this occurs, rely on the LEDs on your computer
for accurate power status information.

Turning the APM setting to Off also turns off the
BIOS power management.  If you want to turn off
APM, but not the BIOS power management, place REM
before the APM device driver statement in your
CONFIG.SYS file, and then restart your system to
invoke the change.

For example:

  REM DEVICE=C:\OS2\APM.SYS

                                        on your selection.

                                    Note:  You cannot change the size of
                                           the Power window.

A full-status Power window displays the following
information:

o   Battery life.  This information is displayed
    as a power gauge that shows the power level of
    the battery compared to the capacity of the
    battery.  When the power gauge indicator is
    completely shaded, the battery is at full
    power.  The shaded area of the gauge moves up
    or down as the battery power level increases
    or decreases.  When the power gauge indicator
    is dimmed, there is no battery in the computer
    or the computer cannot provide battery
    information.

o   Power source for the computer.  If the system
    cannot determine the power source, no power
    source information is displayed.

o   Battery state, which is the charge state of
    the battery.  Battery state information is
    displayed as follows:

    High        Battery charge is OK; continue
                using your computer.

    Low         Recharge the battery or switch to
                another power source such as
                another battery or AC power.

    Critical    Battery charge is depleted.
                Recharge the battery or switch to
                another power source immediately
                to avoid a system failure or data
                loss.

    Charging    System is restoring the battery
                charge.

    Unknown     System cannot determine the
                battery state or there is no
                battery in your computer.


Suspend Mode


                                    To set the suspend mode:

                                    1.  Display the Power object pop-up
                                        menu.

                                    2.  Select Suspend.

When suspend mode is activated, battery power is
conserved by dimming the display and turning off
devices that are not in use.

If Confirm on power status changes is set in the
Power - Settings notebook, a message that asks you
if you want to continue is displayed before
switching to suspend mode.

Note:  Different computers have different
       procedures for exiting suspend mode and
       resuming operation.  Refer to the
       documentation that came with your computer
       for information about its suspend mode
       features.

       After you exit suspend mode, you will
       notice a startup delay before you can
       resume operation of your system.  This
       delay might be a few seconds, depending on
       your system.


PCMCIA


OS/2 2.1 provides software support for Personal
Computer Memory Card International Association
(PCMCIA) hardware.  PCMCIA(**) is the standard for
PC card adapters associated with portable
computers.  A PC card is a small form-factor
adapter about the size and shape of a credit card.
You can use PC cards with laptops, notebooks,
tablets, and other portable computer systems that
are equipped with a PCMCIA slot.

To install PCMCIA, use Selective Install and

CHAPTER 5.  STARTUP
___________________

>   On page 93, replace all text after the first
    paragraph with the following:

    If you add hard disk drives or partitions
    after the installation of the OS/2 operating
    system, you should edit the CONFIG.SYS file
    and update the AC:x parameter to reflect the
    new additions.  AC: starts the auto-check
    feature on the specified drives when the
    system shuts down improperly.  The value x
    represents the letters of the disks or
    partitions on the system that you want to
    check.

    For example, if you want to check disks C and
    D and your existing DISKCACHE statement is:

           DISKCACHE=64,LW

    Add the AC: parameter to the statement as
    follows:

           DISKCACHE=64,LW,AC:CD


CHAPTER 6.  DRIVES

>   On page 97, add the following note to the Tree
    view paragraph:

    Note:  When an additional folder is opened
           from a folder that is in tree view, if
           the default for the additional folder
           is also tree view, it is overridden and
           displayed in an icon view.  There is no
           need to open it again in tree view
           because it is already shown in the
           parent folder's tree view.

>   On page 185, add the following note before the
    section titled "Viewing Program Object
    Settings":

    Note:  The PgUp and PgDn keys on the numeric
           keypad should not be used to move

CHAPTER 18.  USING WINDOWS PROGRAMS
___________________________________

>   On page 196, replace the last sentence in the
    section titled "Character Map" with the
    following:

    Character Map works with Windows and OS/2
    programs.

>   On page 199, replace all the text after the
    first paragraph in the section titled
    "Locating Window Programs" with the following:

            When you run the Migrate Applications program for existing
            Windows programs, the WIN-OS/2 Groups folder is created
            and placed on the desktop.  The WIN-OS/2 Groups folder
            contains folders of Windows application programs that
            reside in the default groups, WIN-OS/2 Accessories and
            WIN-OS/2 Main.  A group is a set of Windows programs that
            are related.


            The Windows Programs folder contains Windows programs that
            have settings preselected to optimize the performance of
            your program.  Windows programs that do not belong to any
            group are migrated to the Windows Programs folder.


            The Additional Windows Programs folder contains Windows
            programs that have default settings for your programs.
            (If these programs do not run correctly, you can specify
            other settings.)

    For example, if you have CorelDraw(**) for
    Windows installed, when you run the Migrate
    Applications program, a folder for all the
    CorelDraw programs is created and placed in
    the Additional Window Programs folder.  Now
    you have access to all the CorelDraw programs
    in one folder.  For more information about
    migrating programs, see "Migrate
    Applications".


>   On page 201, replace the paragraph at the top
    of the page with the following:

    When you change the value of a setting before
    you start a session, the changes affect all
    programs running in that session.  When you
    change the value of a setting while the
    session is running, the changes will not have
    any effect until you restart the session.  If
    you want the changes to remain whenever you
    start a specific session or program, you must
    save the changes.

>   On page 201, add the following note before the
    section titled "Running Window Programs in
    WIN-OS/2 Sessions":

    Note:  The changes will not take effect until
           you restart the session.

>   On page 202, replace the last sentence with
    the following:

    To run more than one Windows program, repeat
    the above steps as needed.

>   On page 205, replace the last paragraph before
    the section titled "Using the Clipboard and
    Dynamic Data Exchange Features" with the

    beginning with "If the cell you select..." to
    after the delete instructions.  Move the
    paragraph beginning with "If the work sheet is
    not synchronized..."  to after the second set
    of instructions.

    o   16-bit protect-mode APM in BIOS
    o   32-bit protect-mode APM in BIOS

    Laptop computers that have no APM support in
    BIOS or have only real-mode APM are not
    supported by OS/2 2.11 Advanced Power
    Management.

    The DOS utility program APMHERE, which is
    available on the IBM BBS, can quickly
    determine whether your machine has Advanced
    Power Management support in conformance to the
    APM 1.0 Specification (dated 1/91).  Systems
    with BIOS dates prior to January 1991 will not
    have the protect-mode APM support in their
    BIOS.

    Laptop Computers with APM Support

    The table that follows lists the laptop
    computers that have Advanced Power Management
    support.  (This list represents only systems
    tested as of January 27, 1994.)

    Note 1:  To run OS/2 2.11 in these models,
           change the "BASEDEV=IBM1S506.ADD"
           statement in CONFIG.SYS to the
           following:

             BASEDEV=IBMINT13.I13

    Note 2:  For these models, the following BIOS
           information is displayed on start up:

             Systems Soft Bios for 80486/82C463 v1.01 (2069-09)

           Contact Systems Soft, Inc.
           (508-651-0088) for a corrected version
           of BIOS.

    Note 3:  The OS/2 APM calls the BIOS APM once
           per second to check if it is OK to do a
           suspend.  The following BIOS do not
           return OK to suspend if the video
           display is active or changes during the
           CMOS suspend timeout:

           o   PhoenixBIOS Version 1.03
           o   Phoenix NoteBIOS 486/OPTi463
               Version 1.03
           o   PhoenixMISER V2.0

    Laptop Computers without APM Support

    The table that follows lists the laptop
    computers that do not have APM support in
    their BIOS; however, they can be configured to
    run OS/2 2.11 if APM is not installed. (This
    list represents only systems tested as of
    January 27, 1994.)

    If you have installed OS/2 APM, ensure that it
    is removed properly by doing the following:

    o   Remove the following two APM device
        statements from CONFIG.SYS:

          DEVICE=C:\OS2\APM.SYS
          DEVICE=C:\OS2\MDOS\VAPM.SYS

    o   Delete the APM.SYS and VAPM.SYS files from
        the corresponding hard-disk
        subdirectories.  This gains about 1 second
        in startup and frees up hard-disk space.

    Note 1:  To run OS/2 2.11 in these models,
           change the "BASEDEV=IBM1S506.ADD"
           statement in CONFIG.SYS to the
           following:

             BASEDEV=IBMINT13.I13

    Note 2:  For OS/2 2.11 APM, access the IBM BBS
           and download the following 3 files:

           o   TGSFX.COM (located in file area 4)
           o   RFL40SXA.TG0 (located in file area
               27)
           o   L40PWR.ZIP (located in file area
               37)

           Execute TGSFX.COM to install the
           TELEGET.EXE program.  Then do the
           following:

           1.  Create a new L40SX reference
               diskette by using TELEGET.EXE to
               unpack RFL40SXA.TG0 onto a 1.44MB
               formatted diskette.

           2.  Use PKUNZIP to unzip the L40PWR.ZIP
               to obtain new IDLE.EXE and
               PWRMGMT.SYS files.

           3.  Replace the IDLE.EXE and
               PWRMGMT.SYS files on the newly
               created L40SX reference diskette
               with the new IDLE.EXE and
               PWRMGMT.SYS files obtained from the
               previous step.

           4.  Restart L40SX with the resulting
               reference diskette in A drive and
               configure with APM.

           5.  Verify the APM configuration by
               selecting VIEW configuration from
               the installation menu.

           6.  Exit the configuration.

           7.  Power off the computer and restart
               OS/2.

    Note 3:  Contact the manufacturer for newer
           versions of their BIOS that have APM
           support.

    Note 4:  These models require the Toshiba APM
           driver (OS2RES.EXE) available from the
           Toshiba BBS (714-837-4408).  This
           driver will provide partial power
           management capabilities under OS/2
           2.11.

    Note 5:  While running OS/2, you can use the
           special power-saving keys but the
           additional capability of OS/2
           protect-mode APM is not supported.

APPENDIX C.  BACKING UP AND RESTORING YOUR DESKTOP
__________________________________________________

>   On page 431, replace the last note with the
    following:

    Note:  The name of your DESKTOP directory
           might be slightly different if you use
           HPFS or if you previously replaced your
           desktop.  To find the actual name of
           your DESKTOP directory currently in
           use, display the Settings notebook for
           the desktop and select the File page.
           The current desktop name is shown under
           Physical name.

>   On page 431, replace the last line with the
    following:

    BACKUP C:\OS2\DESKTOP A: /S

>   On page 433, replace lines #10, #11, and #12
    with the following instructions:

        10. Delete the existing desktop directory
        and its subdirectories.

        11. Use the RESTORE command to copy the
        DESKTOP directory and its subdirectories
        from the diskette to the hard drive.

          RESTORE A: C:\OS2\DESKTOP /S

        This will ensure that the desktop folders
        are displayed correctly.

        12. Remove the diskette from drive A.

        13. Press Ctrl+Alt+Del to restart the
        computer.
