This sub-menu configures North Bridge features

This feature works with Intel’s I/O Acceleration Technology (AT) to accelerate the performance of TOE devices. When this feature is set to ENABLED, it will enhance overall system performance by providing direct memory access for data transferring. Options include ENABLED and Disabled.

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 the card.

This feature allows you to enable Crystal Beach/DCA support for your system. Options include ENABLED and Disabled.

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 Intel platforms, providing you with greater reliability, security and availability in networking and data-sharing. Options include ENABLED and Disabled.

This sub-menu configures South Bridge features.

This feature allows you to enable USB functions in your system. Options are Enabled or DISABLED.

This feature allows you to configure USB ports in your system. Options include 6x6 USB Ports and 8X4 USB PORTS.

This submenu contains further USB configuration options.

This option allows you to enable the use of Legacy USB devices. If this option is set to AUTO, legacy USB support will be automatically enabled if a legacy USB device is installed on the mainboard, and vice versa. The options include DISABLED, Enabled and AUTO.

This setting allows you to select the USB 2.0 Controller mode. Options include Hi-Speed (480 Mbps) and FULL SPEED (12 MBPS).

This option allows you to enable BIOS Enhanced Host Controller Interface support in order to provide a workaround solution for an operating system that does not have EHCI Hand-Off support. When Enabled, the EHCI Interface will be changed from the BIOS-controlled to the OS-controlled. Options include Enabled and DISABLED.

This option allows you to create a dummy Floppy Disk Drive (FDD) that will be associated with the hotplugged FDD later. AUTO creates this dummy device only if there is no USB FDD present. Options include DISABLED, ENABLED and Auto.

This option allows you to enable your SMBUS controller in your system. Options include Enabled and DISABLED.
