            POWEREXEC 4/33 SL OS/2 INSTALLATION FROM FLOPPY DISK FAILS

    PROBLEM:        In the PowerExec, with system BIOS 2.22 or higher, the Cannon
                    floppy drive fails OS/2 installation.

    CAUSE:          The Cannon floppy drive does not complete certain functions in
                    an "AT compatible" timely fashion.  This causes BIOS level I/O
                    to fail.

    SYSTEMS             AST                                        REVISION
    AFFECTED:       PART NUMBER     DESCRIPTION                      LEVEL

                    501191          4/33 SL POWEREXEC Mono             All
                    501192          4/33 SL POWEREXEC Color           All

    SOLUTION:       Replace the existing drive with the current available drive
                    from AST.  Currently available drives do not exhibit this
                    failure.
