The only reason I can imagine it should not work is = addressing the boot-image from the boot-prom.

Or else, it should not be called scsi...

When you look inside a 712, you should expect heat = problems with the drive. Its mounted in polysterene foam, also known = for its perfect heat insulation...

Hence, if you expect or experience heat problems in a = 712, you can remove the insulation and create real mounting = brackets.
