 1.0   CREATING DISKETTE IMAGES FROM THE OS/2 CD
       _________________________________________

  To create diskette images from the OS/2 CD after OS/2
  has been installed, you must first find out how many
  diskettes you will need.  Follow these procedures:

  1.  Place the OS/2 CD in the CD-ROM drive.
  2.  Type the following and then press Enter:

           DIR X:\DISKIMGS\OS2\35  /W

      (where X: is the CD-ROM drive.)
  3.  When a list of files appears on your screen,
      count the files that end with the .DSK extension.
      Each .DSK file requires one formatted high-density
      diskette.

  Use the following command to create each diskette
  image:

    X:\DISKIMGS\XDFCOPY X:\DISKIMGS\OS2\35\diskname.DSK A:

  where:

  X:                       Is the drive letter of the
                           CD-ROM drive.

  \DISKIMGS\XDFCOPY        Is the location and name of
                           the program used to create
                           the diskettes.

  \DISKIMGS\OS2\35         Is the location of the files
                           containing the diskette
                           images.

  diskname.DSK             Is the diskette image file
                           name (for example,
                           DISK0.DSK).

  A:                       Is the drive letter of your
                           3.5-inch diskette drive.

  For example, to create the Installation Diskette
  (DISK0.DSK), type the following and press Enter:

    X:\DISKIMGS\XDFCOPY X:\DISKIMGS\OS2\35\DISK0.DSK A:

  (where X: is the CD-ROM drive and A: is the diskette
  drive.)


 2.0   ARCHIVING THE DESKTOP
       _____________________

  The Archive page of the Desktop Settings notebook
  specifies the drive on which the Desktop archive will
  be stored.

  If you choose to change the default drive, be sure to
  select a drive that has the same file system format as
  the drive that contains the Desktop.  For example, if
  the Desktop is on a drive that is formatted in FAT,
  the drive on which the archive will be stored must also
  be formatted in FAT.

  Use the OS/2 FDISK command to display the file system
  format of the drive on which your Desktop resides.  The
  file system is displayed in the FS Type field.


 3.0   RECEIVING A STARTUP WARNING MESSAGE
       ___________________________________

  If you choose to archive system files, you might receive
  the following warning during system startup:

     There may not be enough room at the target to
     create an archive.  Do you wish to continue?

  This message indicates that there will be less than 10MB
  of free space available in the selected archive hard disk
  partition after the files are archived.  If you select
  Yes, the archiving process will continue.  If you select
  No, the archiving process will not be performed.


 4.0   CUSTOMIZING THE SET AUTOSTART LINE IN CONFIG.SYS
       ________________________________________________

  If you installed this version of OS/2 over a previous
  version of OS/2, the SET AUTOSTART line in your CONFIG.SYS
  file was reset with default values.  To customize the
  SET AUTOSTART line, you must edit your CONFIG.SYS file
  after installing OS/2.


 5.0   INSTALLING THE NEW OS/2 SCHEME PALETTE
       ______________________________________

  If you installed this version of OS/2 over a previous
  version of OS/2 and you migrated your old Desktop (to
  preserve the way you had it set up), the new Scheme Palette
  object that comes in this version of OS/2 will not appear
  in your System Setup folder.  If you want to add the new
  Scheme Palette object, do the following:

  1.  Open OS/2 System.
  2.  Open Command Prompts.
  3.  Open OS/2 Window or OS/2 Full Screen.
  4.  At the OS/2 prompt, type the following and then
      press Enter:

           SCHEME

  This procedure renames your previous Scheme Palette to
  OLD SCHEME PALETTE, makes it a deletable file, and
  creates the new Scheme Palette.  Both objects will
  appear in your System Setup folder.


 6.0   CORRECTING SOUND PROBLEMS AFTER SYSTEM INSTALLATION
       ___________________________________________________

  If your computer produces unusual or repetitive sounds,
  or no sounds at all, after you have installed OS/2,
  you might have a mismatch between the device driver
  parameters supplied by OS/2 and the sound adapter card
  or the BIOS setting of your computer.

  You might see messages similar to the following when you
  try to start OS/2:

       ** RM:IRQ:7 **
       ** RM:DMA:1 **
       ** RM:IO:220 **

  These messages indicate that a device driver failed
  to load because another device is already using the
  designated port, address, or channel.

  To determine if this situation exists, use the RMVIEW
  utility program to display the OS/2 device driver
  types and parameters installed on your computer.  The
  program quickly scrolls through the device types.
  The audio card is in the last section of the devices.

  1.  Open OS/2 Window or OS/2 Full Screen.
  2.  Type the following and then press Enter:

           RMVIEW

  3.  Note the following parameters (where X will be
      replaced by a value):

           I/O = 0X0XXX
           IRQ Level = X
           DMA Channel = X

      These are the parameters that OS/2 is using for
      your audio device.  Record this information.
  4.  Refer to the hardware documentation that came
      with your audio card to determine the hardware
      settings of the audio card.  Note the following
      parameters:

           Port address or I/O = 0X0XXX
           Interrupt level or IRQ Level = X
           DMA Channel = X

      Record this information.
  5.  If the hardware and software settings are not the
      same:
      a.  Open OS/2 System on the OS/2 Desktop.
      b.  Open System Setup.
      c.  Open Selective Install.
      d.  Select the Multimedia Device Support icon.
          The Device Selections and Settings window
          appears.  The audio card appears in the
          Device(s) in System to be Installed window.
      e.  Select the Device Settings push button.  A
          window appears with your port address, DMA
          channel, and Interrupt Level settings.
      f.  Select the values that match the hardware
          settings for your audio card.  Then select
          OK.
      g.  When the Device Selections and Settings
          window reappears, select OK.
      h.  When the System Configuration screen
          reappears, select OK.
      i.  At the OS/2 Setup and Installation screen,
          select Install.
      j.  When the Source Directory window appears,
          select Install.
      k.  Follow the instructions that appear on your
          screen.
  6.  Shut down and restart your computer so that these
      changes will take effect.

  If the sound problem continues, there might be a
  conflict with the BIOS settings of your computer.  To
  determine if this condition exists, you will need:

  o   The hardware utility diskette for your computer
      (if one came with your computer)
  o   The documentation that came with your computer

  When you have the diskette and documentation, follow
  these steps to determine the hardware configuration:

  1.  Insert the hardware utility diskette into drive
      A.
  2.  View the BIOS settings that are configured for
      your computer.  Refer to your computer
      documentation for details about viewing this
      information.
  3.  Compare the IRQ Level that was displayed in the
      RMVIEW utility program with the hardware IRQ or
      Interrupt Level found in your computer
      documentation.  If the hardware IRQ or Interrupt
      Level for the LPT port is enabled at 5 or 7,
      disable it.  Refer to your computer documentation
      for details about disabling and saving the new
      settings.

  NOTE:  OS/2 parallel printing no longer requires
         an IRQ setting.

  If you experience unusual sounds in a WIN-OS/2 session,
  refer to the section called "Adding Windows Audio
  Support" in the online Multimedia book, which is
  located in the Information folder on your Desktop.


 7.0   CHANGING DISPLAY RESOLUTION USING THE SYSTEM OBJECT
       ___________________________________________________

  You can use the System object to change the resolution
  for many of the displays supported by OS/2.  Do the
  following:

  1.  Open OS/2 System on your Desktop.
  2.  Open System Setup.
  3.  Open System.
  4.  Select the Screen tab.  If the Screen page says
      "Page 1 of 2" at the bottom, go to page 2 and
      select your display from the list.  Then go back
      to page 1.
      If the Screen page does not have a page 2, go to
      step 5.
  5.  Select the screen resolution that is supported
      by your display from the Screen resolution
      list.  (Refer to the documentation that came
      with your display for a list of supported
      resolutions.)
  6.  Close the System object, shut down OS/2, and
      restart your computer so that these changes will
      take effect.


 8.0   USING LAPTOP COMPUTERS WITH MONOCHROME MONITORS
       _______________________________________________

  If you are using a laptop computer (such as the IBM
  ThinkPad 750 or 750P) with a monochrome display and
  the Western Digital** display driver is installed, you
  might experience problems with the way the cursor is
  displayed.  For example, when you use Alt+Esc to switch
  from a full-screen session to the OS/2 Desktop, the
  cursor might appear completely black until it is moved.
  In addition, if you use a mouse to change the size of
  a window, you will see a trail of discolored pixels as
  the cursor moves.  These problems do not occur on an
  external color monitor or when the VGA driver is
  installed.

  To install the VGA driver, use Selective Install as
  follows:

  1.  Open OS/2 System.
  2.  Open System Setup.

17.0   RUNNING GAMES USING OS/2
       ________________________

  To help you run some popular DOS and Windows games
  using OS/2, be aware of the following:

  o  When you install some games, you will need to know
     your sound card IRQ address, DMA channel, and I/O
     address.

  o  Create an object on the Desktop and enter the path
     (the directory where you have installed the game) and
     the name of the executable file.  For many games,
     the settings for the game will automatically be set
     for you by OS/2.

  o  If you are using a Sound Blaster** card, you must add a
     SET BLASTER statement to your AUTOEXEC.BAT file.

  o  The following tips will help you play these popular
     games:

     o  Master of Orion**  -  Add a SET BLASTER statement to
        your AUTOEXEC.BAT file.
     o  Link386 Pro**  -  Add a SET BLASTER statement to your
        AUTOEXEC.BAT file.
     o  DOOM** 1.2 and later -  Direct sound effects and music
        to a PC speaker, or set up Doom I with no sound
        settings.
     o  DOOM II  -  Set up the FX selection as a PC speaker
        and the MUSIC selection as your sound card.
     o  TIE Fighter**  -  You might encounter a trap after about
        30 minutes of play in the training session.  This occurs
        in the training session only.
     o  Myst** and The Making of Myst  -  Do the following:

        1.  Edit the SYSTEM.INI file located in the
            \OS2\MDOS\WINOS2 directory and change the
            following statements from:

                 SET TIMERMax386Res=10
                 SET TIMERMax286Res=10
            to:
                 SET TIMERMax386Res=x
                 SET TIMERMax286Res=x
             x is a variable between 8 and 20 depending on your hardware
             platform.

        2.  Save the file.  Then shut down and restart your
            system.
        3.  Get Quicktime** 2.0, which is located on CompuServe,
            as follows:

            a.  Log on to CompuServe.
            b.  Type GO QUICKTIME.
            c.  Follow the instructions menu to download
                Quicktime 2.0.
            If you have a partition with native Windows**,
            you will need to take out references in the
            AUTOEXEC.BAT file to the Windows directories on
            other drives. For example, D:WINDOWS;D:\WINDOWS\SYSTEM.
            After you install Quicktime** 2.0, you can put the
            statements back in the AUTOEXEC.BAT file.

        4.  Install Quicktime 2.0 for Myst and the Making of
            Myst.

        To enable sound for Myst and The Making of Myst, you
        must enable the Windows sound drivers.  For more
        information, see "Adding Windows Audio Support" in
        the Multimedia online book, which is located in the
        Information folder on your OS/2 Desktop.

        To ensure The Making of Myst will work correctly under
        OS/2, do the following:

        1.  Set up a WIN-OS/2 session with the same settings
            as Myst.
        2.  Run The Making of Myst in a WIN-OS/2 full-screen
            session.

     o  THE 7th GUEST**  -  If this game does not work properly,
        contact the game manufacturer for the up-to-date sound

        Spectrum**.

        1.  Add sound drivers or files to the ID\T7G directory.
        2.  For the Pro AudioSpectrum, do the following:

            a.  Open the pop-up menu for the 7th GUEST object.

            h.  Select Save.
            i.  Close the notebook.

        3.  Shut down and restart your system.
        4.  Restart the game.

        If the game still does not work properly, edit the

        your sound card, change the DMA address from the default
        to your card's DMA setting.
