                    PREMIUM TE SYSTEMS AND CUPID PROCESSOR CARDS

    PROBLEM:       When installing an AST FastBoard 4/66D upgrade in a Premium TE
                   system, the system will indicate only 4 megabytes of memory
                   installed and hang when testing the memory cache, or emit one
                   long beep.

    CAUSE:         The FastBoard 4/50D, 4/66D, and Pentium upgrades are not
                   supported in the Premium TE and some early models of the
                   Premium SE systems.

    AFFECTED
    SYSTEMS:       Premium TE systems (M/B P/N202377-001)
                   Premium SE systems (M/B P/N 202377-002)

    SOLUTION:      AST Product Marketing has determined that this problem will
                   not be fixed.
