                             PREMMIA WITH PARITY ERRORS

    PROBLEM:       Premmia systems experiencing c errors under various
                   environments.

    CAUSE:         The cause of the parity errors has been traced to two separate
                   sources.  The first, is a ground bounce within the Texas
                   Instruments TACT84581 chip.  The second, is a defect in the
                   Fujitsu 4MB DRAM design (Fujitsu part number 14400A-70L).

    AFFECTED
    SYSTEMS:       All models of Premmia systems.

    SOLUTION:      BIOS version 1.04 has been released via ECN N114 eliminating
                   the ground bounce.  Fujitsu DRAM part number 814400A-70L has
                   been disqualified under AST part number 104000-678.
