AHCI Configures the SATA controllers to AHCI mode. Advanced Host Controller Interface (AHCI) is an interface specification that allows the storage driver to enable advanced Serial ATA features such as Native Command Queuing and hot plug. SATA Port0-3 Native Mode (Intel P55 Chipset) Specifies the operating mode of the integrated SATA controllers. Disabled Allows the SATA controllers to operate in Legacy IDE mode. In Legacy mode the SATA controllers use dedicated IRQs that cannot be shared with other device. Set this option to Disabled if you wish to install operating systems that do not support Native mode. Enabled Allows the SATA controllers to operate in Native IDE mode. Enable Native IDE mode if you wish to install operating systems that support Native mode. (Default) USB Controllers Enables or disables the integrated USB controllers. (Default: Enabled) Disabled will turn off all of the USB functionalities below. USB Legacy Function Allows USB keyboard to be used in MS-DOS. (Default: Enabled) USB Storage Function Determines whether to detect USB storage devices, including USB flash drives and USB hard drives during the POST. (Default: Enabled) SLI/CF Ultra Performance Allows you to fix the operating bandwidth of the PCIEX16_2 slot to x16 or x8. Auto Lets the BIOS automatically configure this setting depending on the device being installed. (Default) Enabled PCIEX16_2 operates at x16. Disabled PCIEX16_2 operates at x8. Azalia Codec Enables or disables the onboard audio function. (Default: Auto) If you wish to install a 3rd party add-in audio card instead of using the onboard audio, set this item to Disabled. Onboard H/W 1394 Enables or disables the onboard IEEE 1394 function. (Default: Enabled) Onboard H/W LAN1/2 Enables or disables the onboard LAN function. (Default: Enabled) If you wish to install a 3rd party add-in network card instead of using the onboard LAN, set this item to Disabled. Green LAN When the onboard LAN function and Green LAN are enabled, the system will dynamically detect if a LAN cable is connected or not. If not, the corresponding LAN controller will be disabled automatically. (Default: Disabled) - 55 - BIOS Setup
