North Bridge Configuration

This feature allows the user to configure 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 a TOE device, which is a specialized, dedicated processor 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 a 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 efficiency. Prefetching too fre- quently 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.

IOH PCI-E Max Payload Size

Some add-on cards perform faster with the coalesce feature, which limits the payload size to 128B; while others, with a payload size of 256B which inhibits the coalesce feature. Please refer to your add-on card user guide for the desired set- ting. The options are 256B and 128B.
