                        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.
