 1.0   CREATING DISKETTE IMAGES FROM THE OS/2 CD
       _________________________________________

  To create diskette images from the OS/2 CD after OS/2
  Warp 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 DIR X:\DISKIMGS\OS2\35  /W (where X: is the
      CD-ROM drive) and press Enter.
  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 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  ENHANCED IDE HARD DRIVES GREATER THAN 528MB
      ___________________________________________

  If you have an Enhanced IDE hard drive that has a
  capacity of greater than 528MB (greater than 1024
  cylinders), note the following restrictions:

  The FAT file system is limited to partition sizes of
  less than 1024 cylinders.

  The HPFS file system can support data partitions that
  are greater than 1024 cylinders.  However, the partition
  from which OS/2 is started cannot be greater than 1024
  cylinders.  The HPFS file system can support drives up
  to 2GB.


 3.0  MULTIPLE VERSIONS OF WINDOWS
      ____________________________

  OS/2 Warp does not support multiple versions of
  Windows (for example, Windows 3.1 on drive D and
  Windows for Workgroups** 3.1 on drive E) or multiple
  installations of the same Windows version (for
  example, Windows 3.1 on drive D and Windows 3.1 on
  drive E).


 4.0  WIN32S VERSIONS 1.0 AND 1.1 APPLICATIONS
      ________________________________________

  Install your Win32s applications in a WIN-OS/2*
  Full-Screen session.  You can then run your Win32s
  applications in either a WIN-OS/2 Window or Full-Screen
  session.


 5.0  REPETITIVE SOUNDS OR NO SOUND AFTER SYSTEM
      __________________________________________
      INSTALLATION
      ____________

  If your computer produces unusual or repetitive
  sounds, or no sounds at all, after you have installed
  OS/2 Warp, 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.

  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 an OS/2 Window or Full Screen session.
  2.  Type the following:

        RMVIEW (press Enter)

  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.
  4.  Refer to the hardware documentation that came
      with your audio card to determine the hardware
      settings of your audio card.  Note the following
      parameters:

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

  5.  If hardware and software settings are not the
      same:
      a.  Select OS/2 System from the OS/2 Desktop.
      b.  Select System Setup.
      c.  Select Selective Install.
      d.  Select the Multimedia Device Support icon.
          The Device Selections and Settings window
          appears.  The audio card appears in the
          Devices(s) in System to be Installed window.
      e.  Select the Device Settings push button.  A
          window appears with your port address, DMA,
          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
  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 hardware
      documentation for details about viewing this
      information.
  3.  Compare the IRQ Level from the RMVIEW utility
      program display with the hardware IRQ or
      Interrupt Level found in the hardware
      documentation.  If the hardware IRQ or Interrupt
      Level for the LPT port is set to enable at 5 or
      7, disable it.  Refer to your hardware
      documentation for details about disabling and
      saving the new settings.

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

  If you experience unusual sounds in a WIN-OS/2*
  session, refer to the online help contained in the
  Multimedia book located in the Information folder on
  your Desktop.


 6.0  DESKTOP SETTINGS NOTEBOOK
      _________________________

  When using the Archive page of the Desktop Settings
  notebook, specify a drive that is managed by the same
  file system as the drive on which your Desktop
  resides.  For example, if your Desktop is managed by
  the FAT file system, do not specify a drive for an
  Archive location that is managed by HPFS.

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


 7.0  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, changing the size of
  a window with the mouse can leave 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.


 8.0  LOTUS NOTES DOES NOT SUPPORT COMET CURSOR
      _________________________________________

  You cannot use the OS/2 Warp Comet Cursor with
  Lotus Notes.


 9.0  LOTUS APPROACH 3.0 NEEDS TO HAVE MEMORY SETTING
      _______________________________________________
      ADJUSTED
      ________

  To use Lotus Approach 3.0, change the DOS memory
  setting DPMI_MEMORY_LIMIT from 64 to 10 before you
  run the application.  Do the following:

  1.  Display the pop-up menu for the Lotus Approach
      3.0 object, the WIN-OS/2 Window object, or the
      WIN-OS/2 Full Screen object.
  2.  Select Settings.
  3.  Select the Session tab.
  4.  Select the WIN-OS/2 Settings push button.
  5.  Select the last radio button, All DOS and
      WIN-OS/2 settings.
  6.  Select OK.
  7.  Scroll down to DPMI_MEMORY_LIMIT and select it.
  8.  Change the value from 64 to 10.  Then select
      the Save push button.
  9.  Close the Settings notebook.
