TOS will not solve the problem.
BMS upgrade chip will solve the provblem.

The ATARI Driver and formatter only support 1 drive, (logical unit 0) on
each SCSI device. Period.

When you add the second drive (Easy), you need more general software.
Currently the SUPRA software is available from SUPRA, or their dealers.
Apparently, Supra allows their dealers to make you a copy of the software.
(Dont use ICD, its got some traps in it to make it fail on other hardware.)

Summary:  If you add a second drive, you need a formatter/partitioner that
will ask you about more than 1 LUN on a SCSI device.
And, you need a driver (replaces AHDI) that will look at more that one
LUN per SCSI device.
