CORRUPT NVRAM ERROR WITH MANHATTAN P


PROBLEM

Manhattan P servers using the dual-channel integrated NCR SCSI controller 
may exhibit an error message on boot, indicating that the NVRAM is corrupt, 
bad, or has been lost.


CAUSE

EISA configuration has assigned the NCR SCSI controllers' memory address to 
an address that is in use by the system board's resources.  EISA Configuration 
has not reserved the space for the system resources, and assigns the space to 
the integrated NCR SCSI controllers.


SYSTEMS AFFECTED
AST PART NUMBER AND DESCRIPTION           REVISION

501502-XXX          Manhattan P5090       Non-disk array models


SOLUTION

AST EISA Configuration Utility (EISACU) release 1.06 
(AST Part Number 911371-037) reserves the correct system board resources, 
and will assign the integrated NCR SCSI controllers to another address.
