Sounds just like the Cirtech SCSI and Cirtech InSyder SCSI cards - drive is
divided up into 32MB chunks (+ 1 partition for what remains). No partition
map required. The Cirtech SCSI card used a supplied DRIVER.SYSTEM to install
up to 3 extra partions per drive under all versions of P8. The InSyder is
better and compatible with P8 v2.x remapping.

The Cirtech cards also have this capability. I have a 40MB & a 200MB shared
between two //e computers with two InSyder cards that I picked up for $3
each at Kansasfest.
