	I know nothing about the internal drives, and even less about hardware.
However: It might be possible to write-disable partitions on an Apple SCSI
card.

	Keith: Would it be ok to modify a DIBTAB so that the w field in the
device status byte would show that the drive cannot be written to? Or, for
that matter, would it be possible to set the online bit to show that the
device isn't even online? If this would work, would it work in future
revisions?
