                      Bravo MS Memory Problems Using IBM SIMMs

    PROBLEM

    The Bravo MS system may experience erroneous problems when using 4 MB
    and 8 MB SIMMs.  For example:

         The program may fail.
         The system may not boot.
         Files may be corrupted.

    CAUSE

    Some SIMMs manufactured by IBM have shown to emit non-standard
    amounts of noise.  This noise has adverse effects on the performance and
    durability of the Bravo MS system, passing invalid information to the CPU.

    SOLUTION

    The solution is as follows:

    1. If experiencing memory-related problems on any Bravo MS system,
    identify the SIMM manufacturer.  The IBM SIMMs are identified by an IBM
    sticker.

    2. If the SIMMs are not identified as IBM 'BE' series, they may need to be
    replaced.  The 'BE' is placed to the right of the IBM logo.

    To replace the SIMMs, call AST's Technical Support at (800) 727-1278 and
    request a Return Authorization Number (RAN) for IBM's 4 MB or 8 MB
    upgrade or SIMM kit.
