BIOS

Introduction

The BIOS is a program located in the Flash Memory on the motherboard. This program is a bridge between motherboard and operating system. When you start the computer, the BIOS program gains control. The BIOS first exectues an auto-diagnostic test called POST (Power on Self Test) for all the necessary hardware, it detects the entire hardware devices and configures the parameters of the hardware synchronization. After these tasks are completed, BIOS will give control of the computer back to operating system (OS). Since the BIOS is the only channel for hardware and software to communicate with, it is the key factor of system stability and of ensuring your system performance at best. In the BIOS Setup main menu, you can see several options. We will explain these options in the following pages. First, let us see the function keys you may use here: Press <Esc> to quit the BIOS Setup. Press ↑↓←→(up, down, left, right) to choose the option you want to confirm or modify. Press <F10> to save these parameters and to exit the BIOS Setup menu after you complete the setup of BIOS parameters. Press Page Up/Page Down or +/- keys to modify the BIOS parameters for the active option.

Enter BIOS

Power on the computer and press <Del> key immediately to enter Setup. If the message disappears before your respond but you still wish to enter Setup, restart the system by turning it OFF then ON. You may also restart the system by simultaneously pressing <Ctrl>, <Alt> and <Delete> keys.
