    BOOTING OFF OF NCR 8100S PCI SCSI HBA CARDS

    PROBLEM

    When the NCR 8100S card is installed on a Manhattan P or V, any SCSI drives
    attached to the system may not boot.

    CAUSE

    The NCR 8100S controller does not have a BIOS ROM on it.  SCSI drives can not
    boot from a controller without a ROM.

    SYSTEMS AFFECTED : Manhattan P and V Systems.

    Boot off of the integrated SCSI controller.  Edit the CONFIG.SYS file and
    add the line

    DEVICE=C:\path\DOSCAM.SYS

    where 'path' is the location of the DOSCAM.SYS file.  After rebooting,
    drives on the NCR 8100S controller will be recognized.
