Mixing UltraSCSI &U2 (LVD) SCSI Devices

The PCI-SIU2 supports legacy drives. However, in order to maximize perfor-
mance of SCSI I/O’s it is recommended to only connect LVD (Ultra2) devices
to the PCI-SIU2. If a legacy device is attached to the PCI-SIU2, the devices
attached will be switched to SE (Single-Ended) mode. Then all SE SCSI pa-
rameters (# of devices, cable length, cable impedence) will become in effect.
