I have (had?) a Supra 20MB drive that originally did not work with Minix.
This drive was attached with a version 2 Supra host adapter card. Given
this and version 2.01 formatting software, Minix would not use this drive.
I now have the version 5 host adaptor (I think it's #5, it has the pass-thru
DMA connector as well as the onboard clock) and version 3.2 formatting
software with the same drive mechanism, and this combination does work.

Unfortunately I can't verify if the new formatter and old host adaptor
will work, since the old one is quite thoroughly fried. I am now using
Minix on a 40MB Miniscribe 8051S, with the 20MB Miniscribe 8425S attached
as a GEMDOS only drive, with the new Supra host adaptor.
