The 9133H has a set of 3 jumpers on the controller

have no idea what all 16 possiilites actually are. Anyone?
In such cases I usually throw the firmware image at the IDA disassembler
(we actually have bought two licenses) and look how it works. It shouldn't
be a problem at all to locate the geometries table, and I would simply
patch the firmware to work with the "new" drive.
For example, I have disassembled the firmware of the HP 7958A and found
out how to low-level format a foreign ESDI disk (the original one had
failed) with different geometry (the geometry is read from the drive since
it is ESDI). In this case HP-UX mediainit in guru mode was my friend.
