change order (ECO) on the system when PCI ports are not active. The options
are PCU Squelch exit ignore option and Reset the SQ FLOP by CSR option.
IOAT Conguration
Enable I/OAT
Select Enable to enable Intel I/OAT (I/O Acceleration Technology), which signi-
cantly reduces CPU overhead by leveraging CPU architectural improvements
and freeing the system resource for other tasks. The options are Enable and
Disable.
No Snoop
Select Enable to support no-snoop mode for each CB device. The options are
Disable and Enable.
Relaxed Ordering
Select Enable to enable Relaxed Ordering support which will allow certain trans-

Select Enable to use Intel Virtualization Technology support for Direct I/O VT-d
support by reporting the I/O device assignments to the VMM (Virtual Machine
Monitor) through the DMAR ACPI tables. This feature offers fully-protected I/O
resource sharing across Intel platforms, providing greater reliability, security and
availability in networking and data-sharing. The options are Enable and Disable.

Disable.
Use this item to set the limit on power performance states for the run-time processor,
with P0 being the state with the highest power and frequency, and P1, a step lower in
performance than P0, with its voltage and frequency scaled back a notch. The options
are Between P1/P0 and Below P1.
