How to Set Up an Asus Motherboard BIOS

Updated April 17, 2017

All motherboards include a BIOS, or Basic Input Output System. The BIOS controls the order in which system drives boot during start-up, regulates system bus speeds and controls integrated motherboard peripherals. Even though each motherboard BIOS is configured for optimum specifically for that motherboard, users may want to make adjustments according to the configuration of their individual computers.

Asus motherboards are used in many premade computers and are also common among users who build their own PCs. The Asus BIOS may differ slightly between motherboards, but the basic configuration procedures are very similar.

Enter the BIOS set-up as the computer starts. This is usually done by pressing one of the function keys during start-up, such as "F1" or "F2."

Set the date and time in the Main Options of the BIOS, and configure the settings for your storage devices. If BIOS is set to autodetect your storage devices, you can speed up boot time by specifying what drives are installed on your system.

Move over to the "Advanced" tab to configure these features. You should definitely enable some of these features, such as level 1 and level 2 cache. You are also able to set the boot sequence, so disable any drives that your system will not boot from. Leave the settings on the "Advanced Chip-set Features as-is, since this section is most probably already optimised for your motherboard.

Configure your computer's integrated peripherals. This includes USB controllers and serial ports. Disable any peripherals or ports that you will not use.

Disable the BIOS power management settings on Windows-based machines, since Windows has built-in power management features.

Set the PnP/PCI Configurations to "auto" or leave them at their default settings. These will be the most effective settings for most users. Disable PCI/VGA Palette Snoop unless you are sure that you have a device that will require it.

Create new user and BIOS passwords in the "Security" tab if desired.

Adjust your fan speed and temperature control settings if your BIOS features a Hardware Monitor or similar function.

Save any changes you have made and exit the BIOS.
