Novell encourages all users to use this newer DCB.DSK disk driver!  This is
not a patched version of the old driver, this is a completely re-written
driver.  ***PLEASE READ THE FOLLOWING INFORMATION BEFORE USING THIS NEW
DCB.DSK DISK DRIVER!***

When a NetWare 386 partition is created with a drive type defined as
Generic SCSI under the older DCB.DSK disk driver (date 08/03/89 - file size
16034) and you upgrade to the new DCB.DSK disk driver (date 02/06/90 - file
size 17331) you will not be able to mount the volume(s) on that partition. 
When attempting to mount the volume(s) you will receive the error: "There
are no accessible disk drives with NetWare partitions...".  When you load
the install NLM, and go into "Disk Options", "Partition Tables", you will
receive the following error: "NetWare 386 partition relative sector 32 and
size XXXXX do not match the ending cylinder XXX, head XX, sector XX".  You
will need to select "Create NetWare Partition" and create a new partition
using the new DCB.DSK driver mentioned above.

***PLEASE MAKE SURE THAT YOU HAVE A CURRENT BACKUP OF ALL DATA CONTAINED ON
THE DRIVE(S) BEFORE CREATING THE NEW PARTITION, AS CREATING A NEW PARTITION
WILL DESTROY ALL EXISTING DATA, BINDERIES AND TRUSTEE ASSINGMENTS
INCLUDED!***

After creating the new partition and volume(s), you can log in to the
server and restore all backed up data.

These changes made to the heads, sectors and cylinders (partion table
information) were made to adhere as closely as possible to the industry
standard partition table information that applies to devices that cannot
report heads, sectors and cylinders.

We re-emphasize, this applies to GENERIC SCSI ONLY.

May we also re-emphasize that Novell has never claimed that the Generic
SCSI option would successfully interface with all SCSI type hard drives,
nor do we support it that way.

The best option for interfacing larger drives is to purchase a drive from a
drive manufacture that has a NetWare Ready stamp (indicating the heads,
sectors and cylinders) on the drive when shipped from the manufacture and
selecting the NetWare ready option in Disk Set.  This option applies to
NetWare 386 only!
