Enabled .

North Bridge Confi guration
This feature allows the user to confi gure the settings for the Intel North Bridge.
Intel I/O AT
This feature works with the Intel I/O AT (Acceleration Technology) to accelerate
the performance of TOE devices. ( Note : A TOE device is a specialized, dedicated
processor that is installed on an add-on card or a network card to handle some
or all packet processing of this add-on card.) When this feature is set to Enabled,
it will enhance overall system performance by providing direct memory access for
data transferring. The options are Enabled and Disabled.
DCA (Direct Cache Access) Technology (Available when Intel I/O AT is
enabled)
This feature works in conjunction with the Intel I/O AT (Acceleration Technology) to
accelerate the performance of the TOE device. When this feature set to Enabled, it
will enhance overall system performance by providing direct cache access for data
transferring. The options are Enabled and Disabled.
DCA Prefetch Delay
A DCA Prefetch is used with TOE components to prefetch data in order to shorten
execution cycles and maximize data processing effi ciency. Prefetching too 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], [24], [32] , [40], [48], [56], [64], [72], [80], [88], [96], [104], [112], [120]
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 platforms,
providing the user with greater reliability, security and availability in networking and
data-sharing. The settings are Enabled and Disabled .
Active State Power Management
Select Enabled to start Active-State Power Management for signal transactions
between L0 and L1 Links on the PCI Express Bus. This maximizes power-saving
and transaction speed. The options are Enabled and Disabled .
