Notes
doesn't seem to work with software that scans all units (e.g. HDToolBox) - instead, HDInstTools or the GVP FaaastPrep program can be used:
device driver has to be loaded into RAM first, by issuing "version ADD_SCSI.device"
HDInstTools / FaaastPrep has to be called with device driver and unit as parameter ("ADD_SCSI.device unit 0")
no disable switch nor external SCSI connector
