    TITLE: Bravo MS/MS-T 5000 512KB Cache Upgrade

    SUMMARY

       In order to upgrade the Bravo MS/MS-T 5000 systems to 512KB cache,
       the user must first upgrade the system BIOS to version 1.02 or
       higher.

       This issue applies to the following systems: 501951, 501952,
       501954, 501955, 501956, 501972, 503028, 503029, 503027, 503067,
       and 503043.

    ISSUE

       The second-level 512KB cache upgrade requires the system use
       BIOS version 1.02 or higher.

    BACKGROUND

       The Bravo MS system uses a flash BIOS.  This means that the user
       can update the BIOS with a floppy disk image.  The computer does
       not require any hardware changes.

       To determine the system's BIOS version, turn the system ON.
       The BIOS version will appear at the top left corner of the screen.

    ACTION

       To upgrade the system BIOS, download file 05579036.EXE or later
       from one of AST's On-Line! services and follow the README.TXT
       instructions included in the download.
