I have discussed this with Perstor. They do indeed require that
drive type be set to 0. I gather that this is done to force
use of ROM code on the controller board.  While this is said
to be AT standard, it is not compatible with unix as it causes
bypassing of the unix drivers and other software troubles that
I no longer recall.
