1/2) ATX_12V/ATX (2x2 12V Power Connector and 2x12 Main Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all the
components on the motherboard. Before connecting the power connector, first make sure the
power supply is turned off and all devices are properly installed. The power connector possesses
a foolproof design. Connect the power supply cable to the power connector in the correct orientation.
The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not
connected, the computer will not start.
•To meet expansion requirements, it is recommended that a power supply that can withstand
high power consumption be used (400W or greater). If a power supply is used that does not
provide the required power, the result can lead to an unstable or unbootable system.
•The main power connector is compatible with power supplies with 2x10 power connectors.

3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 3-pin system fan header
(SYS_FAN). Each fan header supplies a +12V power voltage and possesses a foolproof insertion
design. When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are
designed with color-coded power connector wires. A red power connector wire indicates a
positive connection and requires a +12V voltage. The black connector wire is the ground wire. The
motherboard supports CPU/system fan speed control, which requires the use of a CPU/system
fan with fan speed control design. For optimum heat dissipation, it is recommended that a system
fan be installed inside the chassis.

English
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.)

When LAN Cable Is Functioning Normally...
If no cable problem is detected on the LAN cable connected to a Gigabit hub or a 10/100 Mbps hub,
the following message will appear:
Link Detected Displays transmission speed
Cable Length Displays the approximate length of the attached LAN cable.
Note: The Gigabit hub will only operate at a speed of 10/100Mbps in MS-DOS mode; it will operate
at a normal speed of 10/100/1000Mbps in Windows mode or when the LAN Boot ROM is activated.
When a Cable Problem Occurs...
If a cable problem occurs on a specified pair of wires, the Status field will show Short and
thenlength shown will be the approximate distance to the fault or short.
Example: Pair1-2 Status = Short / Length = 1.6m
Explanation: A fault or short might occur at about 1.6m on Pair 1-2.
Note: Pair 4-5 and Pair 7-8 are not used in a 10/100 Mbps environment, so their Status fields will
show Open, and the length shown is the approximate length of the attached LAN cable.
