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.
