Until I gave my Quadra 950 the mac53c9x=1 arg the kernel detected _two_ SCSI
busses, one for the internal jack and one for the external jack. This is, I
think, wrong. Things didn't boot. mac53c9x=1 forced it to one SCSI bus and
it booted, although for some reason it won't use the external SCSI jack now.
