    TITLE:  Installing Audio for OS/2 Warp on BMS-T

    ISSUE

       After installing OS/2 Warp v3.0 on a Bravo MS-T system, the sound
       options may not function.

       This issue affects the following systems: 503195, 503196,
       503057,503058, 503195, and 503196.

    BACKGROUND

       OS/2 Warp v3.0 does not ship with driver support for the Crystal
       Audio CS4232/4236 sound chip that ships on the Bravo MS-T.

    ACTION

       The solution is as follows:

       1. Do not select any multimedia devices for installation
          during the standard installation of OS/2 Warp.

          Note: Click on the icon for Multimedia to veify that
          no devices are selected. If a device has been
          selected, highlight it and then remove the device.

       2. Obtain a copy of the Crystal Audio drivers by
          downloading file OS2_160.EXE from the Intel World Wide
          Web site at address:

               http://developer.intel.com/design/motherbd/vs
                    /vs_drive.htm

       3. Format a floppy diskette using the following
          command:

               FORMAT A: /U

       4. OS2_160.EXE is a self-extracting zip file. Copy it to
          a temporary, empty directory on the hard drive and
          execute the file. Once the  files have been extracted,
          execute the following command:

               SW.EXE A:

       5. Open the Multimedia folder by double-clicking on the
          Multimedia icon on the OS/2 desktop. Start the
          Multimedia Application Install program. The
          installation program shows:

          Crystal Audio      (Pre-selected)
          IBM OPL-3 FM MIDI  (Pre-selected)
          IBM MPU-401        (Not Pre-Selected)

       6. Deselect IBM OPL-3 FM MIDI by clicking on the option
          and then pressing the [Enter] key.

       7. When prompted for the number of Crystal Audio devices
          in your system, select 1.

       8. The drivers for your Crystal Audio chip will now be
          successfully loaded. Shutdown and reboot your system
          when prompted.
