    		   Manhattan P&V Reports NCR Timeout Errors

    PROBLEM

    Manhattan P&V systems may report the following error in the Event Viewer
    of Windows NT Servers:

           "The device, \Device\ScsiPort1, Did not respond within the specified
           timeout period" Event Type=9, Event Source=ncr810.

    This error may occur every time the system is booted or rebooted.

    CAUSE

    The NCR SCSIPORT drivers for Windows NT are designed to work with both Narrow
    SCSI and Wide SCSI controllers.  Because Wide SCSI supports 16 devices (twice
    as many as Narrow SCSI), the time required to Poll all devices during device
    driver initialization is increased beyond the allotted time specified by NT.
    This results in a timeout error being forwarded to the Event Viewer. It should
    be noted that the SCSIPORT driver will continue to load regardless of the
    timeout period expiring and this error will not affect the performance or
    functionality of Windows NT.

    SOLUTION

    Upgrade the NCR SCSIPORT drivers for Windows NT to v2.00 using the
    "Windows NT Setup" utility found in the Main Program Group.  The version
    2.0 SCSIPORT drivers have an extended timeout period.

    The new NCR drivers version 1.08, files 11283319.EXE and 1128320.EXE
    (part numbers 911283-319 and 911283-320) can be found on AST's BBS
    (817) 230-6850 (USA).  AST's BBS supports modem speeds up to 28.8k bps.
