Installation Precautions

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.

■ 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.

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.

Clear CMOS Jumper: CLR_CMOS

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.

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 2-3, put it onto pins 1-2 to short them. This will clear CMOS data.

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

► Power Management Setup

All the items related with Green function features can be set up through this menu.

► PC Health Status

This setup enables you to read/change Fan speeds, and displays temperatures and voltages

of your CPU/System.

► BIOS Security Features

The Supervisor/User password can be set up through this menu to prevent unauthorized use

of your computer. If you set a password, the system will ask you to key in correct password

before boot or access to Setup.

► Load Optimal Defaults

The optimal performance settings can be loaded through this menu. However, it may offer bet-

ter performance in some ways (such as less I/O cards, less memory ...etc.), still, it may cause

problem if you have more memory or I/O cards installed. It means, if your system loading is

heavy, set to optimal default may sometimes come out an unstable system. What you need

now is to adjust BIOS setting one by one, trial and error, to nd out the best setting for your

current system.

► Save & Exit Setup

Save setting values to CMOS and exit.

► Exit Without Saving

Do not change anything and exit the setup.

Advanced BIOS Features

► IDE Detect Time Out

This item is used to select the time out value for detecting ATA/ATAPI devices. If the checking

time is over the set value, the system will skip it.

► MPS Revision

This feature is only applicable to multiprocessor motherboards as it species the version of the

MPS that the motherboard will use. The MPS is a specication by which PC manufacturers

design and build CPU architecture systems with two or more processors. MPS 1.1 was the

original specication. MPS version 1.4 adds extended conguration tables for improved

support of multiple PCI bus congurations and greater expandability in the future. In addition,

MPS 1.4 introduces support for a secondary PCI bus without requiring a PCI bridge. If your

operating system comes with support for MPS 1.4, you should keep the setting as the default

1.4. You also need to enable MPS 1.4 support if you need to make use of the secondary PCI

bus on a motherboard that doesn't come with a PCI bridge. You should only leave it as 1.1

only if you are running an older operating system that only supports MPS 1.1.

► PCI Latency Timer

This item is used to set the PCI latency timer. The value is in unit of PCI cycle for PCI device

latency timer register. Setting values are 32, 64, 96, 128, 160, 192, 224, 248.

This feature controls how long each PCI device can hold the bus before another takes over.

The larger the value, the longer the PCI device can retain control of the bus. Low values for

the PCI Latency Timer will reduce the effective PCI bandwidth while higher values means

every PCI device will have to wait longer before they can get access to the bus, but when they

do get access, they can conduct their transactions for a longer time. Normally, a default value

of 64 cycles is set. Some PCI devices may not agree with longer latency times so if you start

facing problems like stuttering sound or a less responsive system, reduce the latency. Higher

values will actually reduce performance as too much time may be allocated to each PCI device

to the disadvantage of other devices on the bus.

► Quiet Boot

This item is used to enable/disable the quiet boot.
