(if the computer boots from a SCSI device). If you change this
setting, the change automatically applies to both SCSI channels.

synchronous data transfer rate that the SCSI card supports. We
recommend that you leave the maximum (default) value of
320 MB/sec.
Packetized—(Default:Yes) Packetized protocol is required to
■
operate at 320 MB/sec. When enabled, this option is available if
it is implemented in the device drivers. However, this option is
not supported by the BIOS.
QAS—(Default:Yes) Quick Arbitration and Selection reduces
■
the overhead of control release on the SCSI bus from one device
to another. This improvement reduces command overhead and
maximizes bus utilization. When enabled, this option is
available if it is implemented in the device drivers. However,
this option is not supported by the BIOS.
