               BRAVO MT FAILS WITH GENERAL PROTECTION FAULT

    PROBLEM:        Winstone bench mark tests fail with "General Protection Fault"
                    during execution of the Lotus 1-2-3 (version 4) bench mark
                    test.  This part of the bench mark loads a simulation of Lotus
                    1-2-3 (version 4) and executes various bench mark tests.

    CAUSE:          The Device Bitmaps is a technique used by the Mach32 driver
                    to gain display speed.  However, it may be incompatible with
                    some applications.
