            Disk Coprocessor Board Upgrade for NetWare 386 v3.10
  
NetWare users who are upgrading to 386 v3.10 may need to upgrade their
Novell Disk Coprocessor Boards (DCB).  
  
NetWare 386 v3.10 was written to support the latest in hardware technology. 
This includes DCBs with revision E or higher of the DCB firmware.  DCBs
with firmware revision D or earlier will not work with NetWare 386 v3.10. 
Under NetWare 386 v3.10, the hard drives will not be visible to the system
when using these older revisions.  This will generally affect 50-pin DCBs
that are a few years old.  

The revision of the DCB firmware is identified at location 817-186 at the
bottom left of the board; the firmware revision will not necessarily
correspond to the DCB board revision number.  Location 817-186 will contain
a 28-pin chip identified by part number 817-186-001.  The revision level
will follow the part number (i.e. 817-186-001E or 817-186-001 rev E).  If
the revision level is D or earlier, an upgrade is necessary. 
  
An upgrade to a DCB with the latest firmware revision is available through
Federal Technologies RMA Department at (800)-366-4526.
