ASUS uses the American Megatrends AMIBIOS for their motherboards and the P6T7 WS Supercomputer is no exception to this rule. The menu is split into Main, Ai Tweaker, Advanced, Power, Boot, Tools and Exit. The Main menu has the System Date, Time Language, Storage Configuration and System Information submenus. The BIOS version installed was 0410 which is newer than that found on ASUS's website.
 Battery
Advanced is where the CPU Configuration, the Chipset features, the onboard devices configuration, the USB Configuration and the PCIPnP is set. CPU Configuration is where the CPU Ratio Setting is set as well as the various features of the CPU including C1E, Virtualization, CPU TM, Execute Disable Bit, HT Technology, SpeedStep, Turbo Mode and C-State. You can also set the number of active processor cores in this menu. The Chipset submenu is where you can disable or enable the Virtualization Technology for Directed I/O. Onboard Devices is where the High Definition Audio is enabled, the Marvell Storage Controller RAID Mode is set, the Marvell SAS controller, the LAN and Firewire is set. The majority of the BIOS tweaking is done in the Ai Tweaker menu. AI Overclock Tuner needs to be set to Manual, DOCP or XMP for the majority of settings to be available to the overclocker. The BIOS is full of settings that can be modified including the CPU Base Clock speed, the PCIE Clock speed and various memory timings. As the P6T7 WS Supercomputer motherboard is designed for the workstation space and not as the super overclocked gaming motherboard the board overclocked to 2.94GHz, which is ok.
