Chapter 2 Hardware Setup

2.1 Choosing a Computer Chassis

• Choose a chassis big enough to install this mainboard.

• As some features for this mainboard are implemented by cabling connectors on the
mainboard to indicators and switches or buttons on the chassis, make sure your chassis
supports all the features required.

• If there is possibility of adopting some more hard drives, make sure your chassis has

sufcient power and space for them.

• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O

shield of the chassis matches the I/O port conguration of this mainboard. You can nd
an I/O shield specically designed for this mainboard in its package.

2.2 Installing the Mainboard

Most computer chassis have a base with many mounting holes to allow the mainboard to
be securely attached, and at the same time, prevent the system from short circuits. There
are two ways to attach the mainboard to the
chassis base: (1) with studs, or (2) with spacers.
Basically, the best way to attach the board is with
studs. Only if you are unable to do this should you
attach the board with spacers. Line up the holes on
the board with the mounting holes on the chassis.
If the holes line up and there are screw holes, you
can attach the board with studs. If the holes line
up and there are only slots, you can only attach with
spacers. Take the tip of the spacers and insert them
into the slots. After doing this to all the slots, you can slide the board into position aligned
with slots. After the board has been positioned, check to make sure everything is OK before
putting the chassis back on.

To install this mainboard:

1. Locate all the screw holes on the mainboard and the chassis base.

2. Place all the studs or spacers needed on the chassis base and have them tightened.

3. Face the mainboard’s I/O ports toward the chassis’s rear panel.

4. Line up all the mainboard’s screw holes with those studs or spacers on the chassis.

5. Install the mainboard with screws and have them tightened.

The mainboard and its component layouts illustrated in this chapter were
based mainly on model “G31”, unless speci cally stated.

Always power off the computer and unplug the AC power cord before adding or removing
any peripheral or component. Failing to do so may cause severe damage to your
mainboard and/or peripherals. Plug in the AC power cord only after you have carefully
checked everything.

To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they are
already fastened on the chassis base and are without mounting-holes on the mainboard to
align with.

2.3 Installation of the CPU and CPU Cooler

Before installing the CPU, please comply with the following conditions:

1. Please make sure that the mainboard supports the CPU.

2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong
direction, the CPU will not insert properly. If this occurs, please change the insert direction
of the CPU.

3. Please add an even layer of heat sink paste between the CPU and CPU cooler.

4. Please make sure the CPU cooler is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.

5. Please set the CPU host frequency in accordance with the processor specications. It is not
recommended that the system bus frequency be set beyond hardware specications since

it does not meet the required standards for the peripherals. If you wish to set the frequen-

cy beyond the proper specications, please do so according to your hardware
specications including the CPU, graphics card, memory, hard drive, etc.

2.3.1 Installation of the CPU

2.3.2 Installation of the CPU Cooler
For proper installation, please kindly refer to the instruction manuals of your CPU Cooler.

2.4 Installation of Memory Modules

This mainboard provides two 240-pin DDRII (Double Data Rate) DIMM slots, and supports

Dual Channel Memory Technology. For dual channel conguration, you always need to install

two identical (the same brand, speed, size and chip-type) memory modules in the DDRII
DIMM slots to activate Dual Channel Memory Technology. Otherwise, it will operate at single
channel mode.

To reach the performance of Dual Channel DDR3, the following rules must be obeyed:
For 2-DIMM dual-channel installation:
Populate DIMM modules of the same type and size on slots [DIMM1]+[DIMM2]

To install system memory:

1. Power off the computer and unplug the
AC power cord before installing or
removing memory modules.

2. Locate the DIMM slot on the board.

3. Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.

4. Align the notch key on the module with
the rib on the slot.

5. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snap into the mounting notch. Do not force the DIMM module in with extra

force as the DIMM module only ts in one direction.

6. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.

Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static

electricity by touching a grounded metal object briey.

Chapter 3 Jumpers & Headers Setup

3.1 Checking Jumper Settings

• For a 2-pin jumper, plug the jumper cap on both
pins will make it CLOSE (SHORT). Remove the
jumper cap, or plug it on either pin (reserved for
future use) will leave it at OPEN position.

• For 3-pin jumper, pin 1~2 or pin 2~3 can be
shorted by plugging the jumper cap in.

How to identify the PIN1 jumpers?
Please check the mainboard carefully, the PIN1 is always
marked with a character "1" or a thick white line.

3.2 CMOS Memory Clearing Header

The time to clear the CMOS memory occurs when (a)
the CMOS data becomes corrupted, (b) you forgot
the supervisor or user password preset in the BIOS
menu, (c) you are unable to boot-up the system
because the CPU ratio/clock was incorrectly set in the

BIOS menu, or (d) whenever there is modication on

the CPU or memory modules.
This header uses a jumper cap to clear the CMOS

memory and have it recongured to the default

values stored in BIOS.

• Pins 1 and 2 shorted
(Default): Normal
operation.

• Pins 2 and 3 shorted:
Clear CMOS memory.

To clear the CMOS memory and load in the default values:

1. Power-off the system then unplug the power cord.

2. Set pin 2 and pin 3 shorted by the jumper cap. Wait for a few seconds. Set the jumper
cap back to its default settings --- pin 1 and pin 2 shorted.

3. Plug the power cord then power-on the system.

4. For incorrect CPU ratio/clock settings in the BIOS, press <Del> key to enter the BIOS
setup menu right after powering on system.

5. Set the CPU operating speed back to its default or an appropriate value.

Chapter 4 BIOS Setup Utility

BIOS stands for Basic Input and Output System. It was once called ROM BIOS when it was
stored in a Read-Only Memory (ROM) chip. Now manufacturers would like to store BIOS in
EEPROM which means Electrically Erasable Programmable Memory. BIOS used in this series
of mainboard is stored in EEPROM, and is the first program to run when you turn on your
computer.

BIOS performs the following functions:

1. Initializing and testing hardware in your computer (a process called "POST", for Power On
Self Test).

2. Loading and running your operating system.

3. Helping your operating system and application programs manage your PC hardware by
means of a set of routines called BIOS Run-Time Service.

4.1 About BIOS Setup

BIOS Setup is an interactive BIOS program that you need to run when:

1. Changing the hardware of your system. (For example: installing a new Hard Disk etc.)

2. Modifying the behavior of your computer. (For example: changing the system time or date,
or turning special features on or off etc.)

3. Enhancing your computer's behavior. (For example: speeding up performance by turning
on shadowing or cache)

4.2 To Run BIOS Setup

First access BIOS setup menu by pressing <F1> key after “POST” is complete (before OS is

loaded). After the rst BIOS be setupped(or loaded default values) and save, the <DEL> key

will be pressed if you will enter BIOS setup menu.

4.3 About CMOS

CMOS is the memory maintained by a battery. CMOS is used to store the BIOS settings you
have selected in BIOS Setup. CMOS also maintains the internal clock. Every time you turn
on your computer, the BIOS Looks into CMOS for the settings you have selected and

congures your computer accordingly. If the battery runs out of power, the CMOS data will

be lost and POST will issue a “CMOS invalid” or “CMOS checksum invalid” message. If this

happens, you have to replace the battery and check and congure the BIOS Setup for the

new start.

4.4 The POST (Power On Self Test)

POST is an acronym for Power On Self Test. This program will test all things the BIOS does
before the operating system is started. Each of POST routines is assigned a POST code, a
unique number which is sent to I/O port 080h before the routine is executed.

Load Optimized Defaults
This option opens a dialog box that let you install optimized defaults for all appropriate
items in the Setup Utility. Select <OK> and then <Enter> to install the defaults.
select <Cancel> and then <Enter> to not install the defaults. The optimized defaults place
demand on the system that may be greater than the performance level of the components,
such as the CPU and the memory. You can cause fatal errors or instability if you install the
optimized defaults when your hardware does not support them. If you only want to install

setup defaults for a specic option, select and display that option, and then press <F9>.

Load Failsafe Defaults
This option opens a dialog box that lets you install fail-safe defaults for all appropriate items
in the Setup Utility: Select <Ok> and the <Enter> to install the defaults. Select<Canel>
and then <Enter> to not install the defaults. The fail-safe defaults place no great demand
on the system and are generally stable. If your system is not functioning correctly, try

installing the fail-safe defaults as a rst step in getting your system working properly again.
If you only want to install fail-safe defaults for a specic option, select and display that

option, and then press <F8>.
