I tried that, and the 5.0.x driver still could not deal with the tape drives
(unfortunately, I don't have the log output available, but I can redo it if
necessary). I also tried disable scsi parity support, and it could not discern
either the tape drive or cdrom at boot time. Right now, I'm running the
machine with covers off, the Adaptec is between a TekRam 390F scsi controller,
and an original Soundblaster 16 (non-pnp) sound card.
