                    PREMMIA GX BOOTING WITH HITACHI SCSI DRIVE


PROBLEM:        The Premmia GX system does not boot into OS/2, version 2.11,
                when a Hitachi DK315C-10 (1GB) SCSI hard disk drive is
                connected to the integrated SCSI adapter.

CAUSE:          Synchronous data transfers are typically faster than
                asynchronous. Some hard disk drives do not handle synchronous
                data transfers.  Therefore, the /!SN or "no synchronous"
                option should only be used if synchronous transfers cause a
                problem.

                501457-601      PREMMIA GX P/90

SOLUTION:       To disable synchronous operations, edit the CONFIG.SYS file in
                the system to read:

                        BASEDEV=OS2CAM.ADD /!SN
