Disk CoProcessor had a ROM checksum error.

Occurs on:  286 only.  This is an Abend error.

Meaning:  This error indicates that the contents of ROM on a Disk
          CoProcessor Board (DCB) did not match its checksum when the
          DCB performed its internal self diagnostics.  As a file server
          boots, NetWare commands the DCB to perform its internal self
          diagnostics before the drives are brought online.

Cause:  This error can be caused by poor connections between the DCB and
        the mother board, by poor power supply regulation, or by a ROM
        or other hardware failure on the DCB.

Solution:  Clean the connector on the DCB and reseat the card.  Reseat
           and check the EPROM on the DCB for bent pins.  Check the
           power supply to make sure that clean, properly regulated DC
           is reaching the DCB.  Replace the DCB if necessary.
