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.
