SCO is quite clear that SCO UNIX 3.2 does not support greater than 
1024 cylinders. If you want to use a drive that has greater than
1024 cylinders, then you ought to purchase a controller such as, the
WD1007 or DTC 6280 (ESDI) if you are running ESDI, and have
the controller bios redefine the disk parameters (cylinder,head,sectors)
which SCO uses. How a particular controller redefines the greater than
1024 cylinder disk is the responsibility of the controller manufacturer.
If it don't work, it's the manufacturers problem, not SCO's. After all,
which comes first, hardware selection, or software selection.
