    BACKGROUND

       N/A

    ACTION

       than 256MB of RAM.  Testing a portion of the memory or using a
       third-party diagnostic program as an alternative will resolve the
       issue.

    NOTES

       AST will not update the Advanced Diagnostics program, version 2.23,
       to resolve this issue.
