Warn in g: Do not unpack the Motherboard from its anti-static
packaging until you are ready to install it.
Like most electronic equipment, your Motherboard may be damaged by
electrostatic discharge. To avoid permanent damage to components ground
yourself while working by using a grounding strap. Otherwise, ground
yourself frequently by touching the unpainted portion of the computer
chassis to drain the static charges.
Handle the Motherboard carefully, holding it by the edges. You are now
ready to start the installation.

1-4 HANDLING THE MOTHERBOARD
To avoid damage to your Motherboard, follow these simple rules while
unpacking:
Before handling the Motherboard, ground yourself by grasping an
unpainted portion of the system's metal chassis.
Remove the Motherboard from its anti-static packaging. Hold the
Motherboard by the edges and avoid touching its components.
Check the Motherboard for damage. If any chip appears loose, contact
your dealer or our tech support immediately.

Warn in g
If there is damage to the board, contact your dealer immediately.
: Do not apply power if the Motherboard appears damaged.
1-5 ELECTROSTATIC DISCHARGE PRECAUTIONS
Make sure to ground yourself before handling the Motherboard or other
system components. Electrostatic discharge can easily damage the
components. Note that you must take special precautions when handling the
Motherboard in dry or air-conditioned environment.
To protect your equipment from electrostatic discharge, take the following
precautions:
Do not remove the anti-static packaging until you are ready to install.
Ground yourself before removing any system component from its
protective anti-static packaging. (To ground yourself, grasp the
expansion slot covers or other unpainted portions of the computer
chassis.)
Frequently ground yourself while working or use a grounding strap.
Handle the Motherboard by its edges and avoid touching its
components.

2-2 INSTALLATION GUIDE
We will now begin the installation of the Motherboard. Please follow the
step-by-step procedure designed to lead you to a complete and correct
installation.
Step1- Install the Central Processing Unit (CPU).
Step2- Install memory modules.
Step3- Install expansion cards.
Step4- Connect cables, case wires, and power supply.
Step5- Power on and enter BIOS setup .
Step6- Install supporting software tools. See Chapter 4 for more info.
Warn in g: Turn off the power to the Motherboard, system chassis,
and peripheral devices before performing any work on the
Motherboard or system.
BEGIN THE INSTALLATION
Step 1 Install the CPU
CPU Mount Procedure:To mount the Pentium® 4 Socket mPGA478
processor that you have purchased separately, follow these instructions.
1. Lift the socket handle up to a vertical position.

Remember to connect the CPU Cooling Fan to the appropriate
power connector on the Motherboard. The fan is a key
component that will ensure system stability. The fan prevents
overheating, therefore prolonging the life of your CPU.
CPU Fan Installation
Your Socket 478 processor kit comes with a cooling fan. Mount the fan on
the processor according to the instructions provided by the manufacturer.
The fan is a key component that will ensure system stability. The fan
prevents overheating, therefore prolonging the life of your CPU.
Note: Remember to connect the fan to the appropriate power source.

This motherboard supports one Dual Channel to your memory, Note that
you can use normal DDR memory for Dual Channel to work. Also note that
for Dual Channel to work 2 modules of equal size and specifications have to
be installed.
The largest memory capacity possible is 3 GB. On this motherboard,
DRAM speed can be set independent form the CPU front side bus speed.
Note that when installing 3GB of memory, your total memory will be less
than 3GB. The reason for this is that the BIOS, PCI and AGP cards claim
part of your CPUs address space.

Step 3 Installation of Expansion Cards
The motherboard has 1 AGP slot and 5 PCI slots.
1. Read the related expansion card’s instruction document before inserting
the expansion card into the computer.
2. Press the expansion card firmly into the expansion slot in the
motherboard.
3. Make sure the metal contacts on the card are seated in the slot.
4. Replace the screw to secure the slot bracket of the expansion card.
5. Install required driver for the operating system you use.
This motherboard only support 1.5V AGP card (4X/8X card). If 3.3V
AGP card is used, the system will not boot-up and the AGPDET LED
will lit.
