Before changing modes, back up
array data and delete existing arrays,
if any. Otherwise, loss of all data may
occur.

only change this mode
selection if prepared to
rebuild RAID array.
Changing the mode could
damage current OS
installation on RAID
volume.

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).
