Chapter 4: BIOS Setup
4.1 BIOS Introduction
BIOS (Basic Input/Output System) is a program located on a Flash Memory on the
motherboard. When you start the computer, the BIOS program will gain control. The BIOS first
operates an auto-diagnostic test called POST (power on self test) for all the necessary
hardware, it detects the entire hardware device and configures the parameters of the hardware
synchronization.

Power on the computer, and pressing <Del> key immediately allows you to enter BIOS
Setup. If the message disappears before you respond and you still wish to enter Setup,
restart the system to try again by turning the system OFF and then ON, or pressing
<Ctrl>+<Alt>+<Delete> keys simultaneously.
