NorthBridge Configuration
3.3.4.11 Intel I/OAT
The Intel I/OAT (I/O Acceleration Technology) significantly reduces CPU overhead
by leveraging CPU architectural improvements, freeing resources for other tasks.
The options are Disabled and
Enabled (default).
3.3.4.12 DCA (Direct Cache Access)Technology
This feature works in conjunction with the Intel I/O AT (Acceleration Technology)
to accelerate the performance of the TOE device. When this feature is set to Enabled,
it will enhance overall system performance by providing direct cache access for data
transferring. The options are
Enabled (default) and Disabled.
3.3.4.13 DCA Prefetch Delay
A DCA Prefetch is used with TOE components to prefetch data in order to shorten
execution cycles and maximize data-processing efficiency. Prefetching frequently
can saturate the cache directory and delay necessary cache accesses. This feature
reduces or increases the frequency the system prefetches data. The options are [8],
[16],
[32] (default), [40], [48], [56], [64], [72], [80], [88], [96], [104], [112], [120].
3.3.4.14 Intel VT-d
Select Enabled to enable Intel's Virtualization Technology support for Direct I/O VT-
d by reporting the I/O device assignments to VMM through the DMAR ACPI
Tables. This feature offers fully-protected I/O resource-sharing across the Intel plat-
forms, providing the user with greater reliability, security and availability in net-
working and data-sharing. The settings are Enabled and
Disabled (default).
3.3.4.15 Active State Power Management
Select Enabled to use the power management for signal transactions between the
PCI Express L0 and L1 Links. Select enabled to configure PCI-Exp. L0 and L1 Link
power states. The options are
Disabled (default) and Enabled.
3.3.4.16 Slot SXB2/SXB3 Width
This feature allows the user to change the link width of a PCI slot as specified in
order to support a riser or add-on card installed in the slot. The Options are x4x4,
x8
(default) and auto.
