Asus Motherboard systems

[Mike Field]

The Asus P2B-DS has three SCSI connectors, two of which are
68pin wide. One of the 68 pin connectors is U2W (and will register
wide drives as U2W under aic7xxx driver/or bios even if they are
not), the other 68 pin is Wide (16-bit scsi). The remaining
socket is narrow.  The wide scsi connector
"is always terminated and will only work as an end device".
If devices are mixed (ie U2 and SE) there is an
*optional* AIC-3860 transceiver to bridge compatibility.
Else the bus defaults to an SE speed.
