                    DESCENT SOFTWARE AND THE CRYSTAL AUDIO CHIP

PROBLEM:     The game software "Descent" by Interplay  mistakenly 
             identifies the Crystal audio chip on the Bravo MS motherboard 
             (202762-xxx) as an Ad Lib Gold card.  


CAUSE:       During the auto detecting process performed by the Descent 
             program the bus between the Crystal CS4322 controller and the 
             Yamaha OPL3 chip is floating, in an undefined state.

SOLUTION:    The user selects "Sound Blaster compatible" manually during 
             the software setup process, instead of using the auto detect 
             process.  This situation holds true for other DOS-based games 
             also.
