--------------------------------------------------------------
DESCRIPTION

OS/2 Warp does not come with any drivers that are 100% compatible
with the Crystal Semi Chip on the motherboard in IBM Desktop 750
computers. If you load any of the drivers that come with OS/2 Warp,
system sounds play, but there is no MIDI support. You also might
see the following error message:

   SYS1201: The device driver "??????.???" specified in the ***
   command on line *** of CONFIG.SYS file was not installed.
   Line *** is ignored.

RESOLUTION

1.  Download the 700AUD.EXE file from either:

    * PC Company Web Site (http://www.pc.ibm.com/) in the
      "File Area," or

    * The IBM BBS (919-517-0001)

2.  Install MMPM/2 support without loading any specific sound-card
    driver.
 
    Note: If you have already installed MMPM with a specific
          driver, manually remove it and then reinstall it as
          follows:

          a. At the Configuration screen during installation or
             Selective Install, make sure the Multimedia Device
             Support section specifies None.

          b. At the OS/2 Setup and Installation screen, make sure
             there is a check mark in the Multimedia section.

    OS/2 Warp should start without any MMPM error messages, and
    the MMPM folder should be on the Desktop.

3.  Open an OS/2 Window session.

4.  Create a temporary directory and place the 700AUD.EXE file in
    it.

    Note: You could also place the file on diskette.

5.  At a command prompt in the temporary directory, type
    700AUD.EXE and press Enter to extract the bundled files.

6.  Open the MMPM folder; then select Multimedia Application
    Install.

7.  Specify the temporary directory (where the extracted 700AUD
    files are) as the source drive.

8.  Highlight the three selections in the Features section:

    * IBM PC 700 Series Crystal Semi Audio
    * IBM PC 700 Series OPL3 MIDI
    * Crystal Semi WIN-OS/2 Audio

    These selections will provide sounds in both OS/2 and WIN-OS/2.

9.  Follow the instructions on the installation screens. Be sure
    to set up the sound chip on available hardware settings.

10. Shut down and then restart the system.
