Fast, Wide Differential SCSI Bus Configuration Constraints
Fast, wide differential SCSI does not work with the narrow, single-en-
ded SCSI. Table C–4 shows the configuration constraints for each
fast, wide differential SCSI device type.

CAUTION: Do not mix narrow single-ended, ultra, wide–
SE and fast, wide differential SCSI peripherals
together on the same bus.
Ultra, Wide Single–Ended SCSI Bus Configuration Constraints
Ultra, wide–SE SCSI does not work with the narrow, single-ended
SCSI or FWD SCSI. Table C–5 shows the configuration constraints
for each ultra, wide–SE SCSI device type.
