                      ASCENTIA 900N AND INTEGRAL TYPE III PCMCIA

    PROBLEM:        When using the Integral Pocket File 42 in an Ascentia 900N
                    system, the following situations may occur:

                    1) When booting with, or loading the Integral Pocket File
                       PCMCIA card into a cold Ascentia 900N system, an error
                       message (QA:6-16 ) may appear and the system may lock-up.
                    2) When running the DOS CHKDSK or SCANDISK utility, the system
                       may lock-up.

                    The above problems occur consistently on 50 Mhz systems and
                    intermittently on 75 Mhz systems.

    CAUSE:          Integral Pocket File 42 ATA PCMCIA is not fully compatible with
                    the Ascentia 900N system.

    SOLUTION:       1) Load the ATA PCMCIA card into a warm system.
                    2) At this time AST has no plans for resolving the issue since
                       it is not AST’s issue to resolve.
