                       POWER EXEC AND INTEL MATH CO PROCESSOR

    PROBLEM:       A 30-60% failure rate will be experienced when running the
                   Floating Point Conformance test using the Intel diagnostics
                   shipped with the math coprocessor.  As a result of these
                   failures, software using floating point calculations will
                   cause the system to hang.

    CAUSE:         Engineering has determined the fault to be with the Intel math
                   coprocessor.

    SYSTEMS
    AFFECTED:      Power Exec 3/25 SL.

    SOLUTION:      A Cyrix math coprocessor will work fine under the same
                   environment until Intel puts out a new chip.
