The drive is jumpered to be the first drive. When in maintenance shell,
accessing /dev/rw0 or /dev/w0 results in the drive spinning up;
accessing /dev/rw1 or higher results in a panic (duh).

I have found something that _might_ be a low-level formatter. I also
found a utility to read the EEPROM and it says it has a 7MB drive which
is wrong. I cannot choose a 70MB drive which is in it. They guy who gave
me the machine said it was operational when the system was shut off and
no changes were made to the hardware config since. Also, the EEPROM disk
selection utility only lists 7, 10, 20, 40MB drives. I do have a 21MB..
does that count as 20? :)

Walter.
