My reading of this would lead me to the conclusion that non-disk SCSI devices
would also not work.  This includes the Tape Backup 40SC, the LaserWriter SC,
Mirus FilmPrinter, etc.  Also, disk initialization (formatting and partition
building) may fail.  I would appreciate hearing more from people who know how
the I/O is "REALLY" handled.
