                 UPGRADING THE BRAVO-II 486/XX BIOS TO VERSION 1.22

    PROBLEM:       When upgrading the system BIOS to version 1.22, the auto drive
                   type is not saved.

    CAUSE:         Version 1.22 does not have an option to enable or disable the
                   shadow BIOS area.  This area is where the auto drive type (97)
                   is stored.

    SYSTEMS
    AFFECTED:      All Bravo-II 486/XX

    SOLUTION:      Before upgrading the BIOS, enable the shadow BIOS region, so
                   the auto option is supported.
