I can think of one way off the top of my head - there may be others.

Use the Control call in a device specific way to write blocks using an
LBA addressing scheme that ignores the partition map. The Unit number
of 1 would be used (assuming the Chinook is plugged directly into the
IIc) as units >1 only come into existence once partitions are defined
(unless a disk with no partitions becomes unit 1 by default). A Status
call could be used to read the partition table. Does the system need
rebooting after a partition is created so that the SMartport can
renumber the devices?

I would be very interested to see the Chinook Utility code. I will
have a look at the Apple SCSI card software and see what it does.
