Installation Precautions

■ Electrostatic discharge (ESD) is the sudden and momentary electric current

that ows between two objects at different electrical potentials. Normally it

comes out as a spark which will quickly damage your electronic equipment.

Please wear an electrostatic discharge (ESD) wrist strap when handling

components such as a motherboard, CPU or memory.

■ Ensure that the DC power supply is turned off before installing or removing

CPU, memory, expansion cards or other peripherals. It is recommended to

unplug the AC power cord from the power supply outlet. Failure to unplug

the power supply cord may result in serious damage to your system.

Please carefully read the following procedures to install your computer :

■ It is suggested to select high-quality, certied fans in order to avoid damage

to the motherboard and CPU due to high temperature. Never turn on the

computer if the CPU fan is not properly installed.

■ We cannot guarantee that your system can operate normally when your

CPU is overclocked. Normal operation depends on the overclocking capac-

ity of your device.

■ If there is any, when connecting USB, audio, RS232 COM, IrDA or S/PDIF

cables to the internal connectors on the motherboard, make sure their

pinouts are matching with the connectors on the motherboard. Incorrect con-

nections might damage the motherboard.

■ When handling the motherboard, avoid touching any metal leads or connec-

tors.

■ If there is a PCI Express x16 graphics card installed in your system, we

recommend using a 24-pin ATX power supply to get the best performance.

■ Before turning on the power, please make sure the power supply AC input

voltage setting has been congured to the local standard.

■ To prevent damage to the motherboard, do not allow screws to come in contact

with the motherboard circuit or its components. Also, make sure there are no

leftover screws or metal components placed on the motherboard or within the

computer casing.

■ If you are uncertain about any installation steps or have a problem related to

the use of the product, please consult a certied computer technician.

2-5 Jumpers

For some features needed, users can change the jumper settings on this motherboard to modify them. This section explains how to use the various functions of this motherboard by changing the jumper settings. Users should read the following content carefully prior to modifying any jumper setting.

Description of Jumpers

1. For any jumper on this motherboard, pin 1 can be identied by the bold silkscreen next to it.

However, in this manual, pin 1 is simply labeled as “1”.

2. The following table explains different types of the jumper settings. "Closed" means placing a jumper

cap on the two pins to temporarily short them. The shorting can also be done by touching two

pins by a screwdriver for a few seconds, but using jumper cap is recommended. It can prevent

hazardous ESD (Electrical Static Discharge) problem.

Jumper Diagram Denition Description

Clear CMOS Jumper: CLR_CMOS1

The motherboard uses CMOS RAM to store the basic hardware information (such as BIOS data, date, time information, hardware password...etc.). Clear CMOS data is the fast way to go back to

factory default when the BIOS settings were mistakenly modied.

1-2 Set Pin 1 and Pin 2 closed

2-3 Set Pin 2 and Pin 3 closed

The steps to clear CMOS data are :

1. Turn off the computer, unplug the power cord from the power outlet.

2. Remove jumper cap from pins 1-2, put it onto pins 2-3 to short them. This will clear CMOS

data.

3. Return the setting to its original with pins 1-2 closed.

4. Plug in the power cord to your computer and turn it on.

5. Go to BIOS Setup to congure new system as described in next chapter.

Normal (Default)

Clear

CLR_CMOS1

■ Disconnect the power cable before adjusting the jumper settings.

■ Do not clear the CMOS while the system is turned on.

This chapter tells how to change system settings through the BIOS
