         PREMIUM EXEC/ADV-NB 386SX/25 LOCKS AFTER SUSPEND WHILE IN DOSSHELL

    PROBLEM:       The system will lock-up after the suspend feature is
                   initiated, while in DOSSHELL.

    CAUSE:         The BIOS has been determined to be the cause of the
                   malfunction.

    SYSTEMS
    AFFECTED:      Premium Exec 386SX/25 and the ADV-NB 386SX/25.

    SOLUTION:      A newer BIOS would fix this issue.  However, there are no
                   plans to turn a new BIOS in the forseable future for these
                   products.
