                     Bravo MS Problem Reading Files from CD-ROM

    PROBLEM

    When executing a file from CD-ROM, the system may lock-up in DOS or cause
    General Protection Fault errors in Windows.

    CAUSE

    When using one or two hard disks on the primary IDE controller, and a CD-ROM
    on the secondary IDE controller, the second IDE controller "First Hard Disk"
    may be incorrectly set as "NONE" in system BIOS.

    SOLUTION

    When the CD-ROM is connected to the secondary IDE controller, the "First
    Hard Disk Type" must be set to "AUTO" in the SETUP Menu due to system
    BIOS design.
