SCSI Connection Notes

The onboard SCSI chipset incorporates an advanced multimode I/O cell
that supports both single-ended (SE), Ultra2, and Ultra160 devices. With
Ultra160 devices, the SCSI bus platform performs at full Ultra160 speeds
(up to 160MB/s) and extended cabling 12m (or 25m in a point-to-point
configuration). When an SE device is attached, the bus defaults to an SE
speed and 1.5m cable length.
