           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.
