The basic input/output system, or BIOS, is the firmware interface for motherboards. The BIOS is the first set of code that opens when you turn on your computer. The BIOS tests, and then begins operating, all hardware on your computer, and it creates the connectivity between your motherboard and all other peripherals, before booting into your operating system. Usually you will not need to update Asus's BIOS firmware, but if you experience incompatibility between hardware then you might be running an old version that needs an update.
