ASUS uses a modified version of the American Megatrends AMIBIOS that is found on most of their motherboards. The menu is split into Main, Ai Tweaker, and Advanced, Power, Boot, Tools and Exit submenus. The Main menu is where the System Time, Date Language, Storage Configuration and System Information are displayed. Here is where you enable the RAID array as well.
The Advanced BIOS is split into CPU Configuration, Chipset, Onboard Devices Configuration, USB Configuration, PCIPnP Configuration menus. CPU Configuration is where you set the CPU Ratio Setting, enable or disable various CPU functions including C1E, Virtualization Tech, Execute Disable Bit, HT, Active Processor Cores, Speedstep, Turbo Mode and C-STATE. The Chipset menu is where you enable High Definition Audio, the Marvell controllers, and the Realtek LAN.
Ai Tweaker is where ASUS put all the overclocking and tweaking for the motherboard. The various settings are listed here in this table along with the settings available.
