There is an Adaptec 1542 SCSI controller which works with OS/2. I'v also
heard about anc Chicony controller which should work with OS/2 too.

These controllers simulate an ST-506 interface an therefore run any OS
which runs on a ST-506 (like WD-1003, WD-1006 controllers).

They may have another interface too to allow access to more than two
drives. The ST-506 interface is limited to two drives and so is the
simulation by the SCSI controller too. But if you have a big enough
SCSI disk (200-600 MB) you will probably not need even a second disk.
