I
Channel 0 Target ID—The physical address a bus initiator uses to
connect with a bus target. Each bus target is assigned a unique target
address. You must select an ID between 0 and 15 for a 16-bit module, or
between 0 and 7 for an 8-bit module. Make sure the ID you select does
not conflict with other IDs. Target IDs are also referred to as the
SCSI ID.
NOTE: Compaq recommends using the default values for the Channel 0 Target ID.
I
Mode—The default mode is NT and it cannot be changed.
I
Bus width—The default mode is 16 bit and it cannot be changed.
I
SCSI transfer rate—The default SCSI transfer rate is 40 MB and it
cannot be changed.
I
Tag queuing—If your host adapter supports tag queuing, check the
Enabled box. Tag queuing permits each initiator to have multiple
commands outstanding and each target to optimize the commands it
receives.
