BIOS Introduction

The BIOS (Basic Input / Output System) is the firmware on the motherboard. It runs first when power is applied, wakes up the hardware, performs the self-test, and boots the operating system. It acts as the "bridge" between the hardware and the OS.

BIOS Main Interface

Press F2 during power-on to enter the BIOS setup screen.

The top of the BIOS screen displays the board model, processor model and frequency, firmware version, and memory size.

• Key hints
