reset the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the

two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two

pins for a few seconds.

•Always turn off your computer and unplug the power cord from the power outlet before

clearing the CMOS values.

•After clearing the CMOS values and before turning on your computer, be sure to remove

the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.

•After system restart, go to BIOS Setup to load factory defaults (select Load Optimized

Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for

BIOS configurations).

16) CI (Chassis Intrusion Header)

This motherboard provides a chassis detection feature that detects if the chassis cover has been

removed. This function requires a chassis with chassis intrusion detection design.

Chapter 2 BIOS Setup

BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the

motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system

startup, saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup

program that allows the user to modify basic system configuration settings or to activate certain system

features. When the power is turned off, the battery on the motherboard supplies the necessary power

to the CMOS to keep the configuration values in the CMOS.

To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned

on. To see more advanced BIOS Setup menu options, you can press <Ctrl> + <F1> in the main menu

of the BIOS Setup program.

To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.

•Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the

operating system.

•@BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the

Internet and updates the BIOS.

For instructions on using the Q-Flash and @BIOS utilities, refer to Chapter 4, "BIOS Update Utilities."

•Because BIOS flashing is potentially risky, if you do not encounter problems using the

current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS,

do it with caution. Inadequate BIOS flashing may result in system malfunction.

•BIOS will emit a beep code during the POST. Refer to Chapter 5, "Troubleshooting," for the

beep codes description.

•It is recommended that you not alter the default settings (unless you need to) to prevent

system instability or other unexpected results. Inadequately altering the settings may result

in system's failure to boot. If this occurs, try to clear the CMOS values and reset the board

to default values. (Refer to the "Load Optimized Defaults" section in this chapter or introduc-

tions of the battery/clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)
