selected SCSI RAID mode,
only change this mode
selection if prepared to
rebuild RAID array.

PCI Priority Arbitration
Disabled
Enabled
Disabled: round-robin priority scheme
for devices on PCI bus.
Enabled: high/low priority scheme for
devices on PCI bus.
Round-robin verses
alternate high/low priority
scheme: In round-robin
which is default, the device
with the lowest req/gnt pair
gets first chance at the bus.
In this case, the baseboard
devices have
an advantage (reg/gnt 0)
followed by the bottom slots
(req/gnt 1), middle slot
(req/gnt 2), and lastly,
the top slot (req/gnt 3). In
the alternate high/low
scheme, each device gets a
equal opportunity
to be the first device after
the PXH timeslot (PXH has
high priority and others are
low priority).
