3.9.2 U320 SCSI Target Config
To set the U320 SCSI Target function, move the cursor bar to the main menu
and click on the U320 SCSI Target Config. The Enabled option supports
Quick Arbitration and Selection (QAS). QAS reduces the overhead of control
release on the SCSI bus from one device to another. This improvement re-
duces command overhead and maximizes bus utilization. Select the desired
function.
