    PROBLEM
    The Ascentia 900N system's display may flash with random color patterns, and
    the system may lock-up after pressing  +< F2> to enter System Setup,
    while running QEMM 7.5 in Stealth Mode.

    CAUSE
    QEMM's Stealth Mode is trying to map memory into an area used by video ROM
    BIOS.
