As far as I know from previous inspections, the SH204 holds DEV 0
selected all the time and never ever releases this selection until
power is switched off. This means that the SH204 host adapter is not
capable of selecting any other SCSI drive than DEV 0. At least, this
is what I have been told. You can, however, put a second MFM drive
of the ST506 type into your SH204 by connecting it to the Adaptec
controller. Using special software (i.e our software 8-) you can
then use the two drives. I don't know if the Supra software supports
two LUNs on a SCSI controller, too.
