Chapter 5: AMI BIOS

DCA Technology (Available when Intel I/OAT is enabled)

Select Enabled to use Intel's DCA (Direct Cache Access) Technology to enhance data transfer efficiency. 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 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 options are Enabled and Disabled.

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 and Enabled.

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 setting. The options are 256B and 128B.

ME-HECI Support

Select Enabled to enable ME-HECI (Host Embedded Controller Interface) support, which will allow the Host OS to communicate directly with the Management Engine (ME) in a standard method for system management, effectively replacing the SMbus. The options are Enabled and Disabled.

South Bridge Configuration

This feature allows the user to configure the settings for the South Bridge chip.

USB Functions

Select Enabled to use USB devices. The options are: Disabled and Enabled.
