WARNING!
WARNING!
Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To
protect them against damage from static electricity, you should follow some precautions whenever you
work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do not have
one, touch both of your hands to a safely grounded object or to a metal object, such as
the power supply case.
3. Hold components by the edges and try not touch the IC chips, leads or connectors, or
other components.
4. Place components on a grounded antistatic pad or on the bag that came with the
components whenever the components are separated from the system.
5. Ensure that the ATX power supply is switched off before you plug in or remove the ATX
power connector on the motherboard.
Installing the motherboard to the chassis…
If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are
no slots to attach the spacers, do not become alarmed you can still attach the spacers to the mounting
holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so be careful
of your hands). In this way you can still attach the motherboard to the base without worrying about short
circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard
PCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact
any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the
board or cause board malfunctioning.

M Please set the CPU host frequency in accordance with your processor’s specifications.
We don’t recommend you to set the system bus frequency over the CPU’s specification
because these specific bus frequencies are not the standard specifications for CPU,
chipset and most of the peripherals. Whether your system can run under these specific
bus frequencies properly will depend on your hardware configurations, including CPU,
Chipsets,SDRAM,Cards… .etc.

Hardware Installation Process
Chapter 2 Hardware Installation Process
To set up your computer, you must complete the following setups:
Step 1- Set Dip Switch
Step 2- Install the Central Processing Unit (CPU)
Step 3- Install memory modules
Step 4- Install expansion cards
Step 5- Connect ribbon cables, cabinet wires, and power supply
Step 6- Setup BIOS software
Step 7- Install supporting software tools

Step 1: Install the Central Processing Unit (CPU)
Step1-1: CPU Speed Setup
The system bus frequency can be switched at 66/100/133MHz by BIOS.
The clock ratio can be switched by adjusting CLK_RATIO(SW1).
(The external frequency depend on CPU .)

Step1-2: CPU Installation
For example: The newest Pentium III processor (FC-PGA2 package).
CPU Top View CPU Bottom View
Socket Actuation Lever
Pin1 indicator
Hardware Installation Process
1. Pull up the CPU socket level
and up to 90-degree angle.
2. Locate Pin 1 in the socket and look
for a (golden) cut edge on the CPU
upper corner. Then insert the CPU
into the socket.
M Please make sure the CPU type is supported by the motherboard.
M If you do not match the CPU socket Pin 1 and CPU cut edge well, it will cause
improper installation. Please change the insert orientation.
11

Step1-3:CPU Heat Sink Installation
1. Press down the CPU socket
lever and finish CPU installation.
3. Fasten the heatsink supporting-base
onto the CPU socket on the main-
board.
2. Use qualified fan approved by Intel.
4. Make sure the CPU fan is
plugged to the CPU fan connector,
than install complete.
M Please use Intel approved cooling fan.
M We recommend you to apply the thermal paste to provide better heat
conduction between your CPU and heatsink.
M Make sure the CPU fan power cable is plugged in to the CPU fan connector,
this completes the installation.
M Please refer to CPU heat sink user’s manual for more detail installation
procedure.

Hardware Installation Process
Step 2: Install memory modules
The motherboard has 2 dual in-line memory module (DIMM) sockets support 4 banks. The BIOS will
automatically detects memory type and size. To install the memory module, just push it vertically into the
DIMM Slot .The DIMM module can only fit in one direction due to the two notch. Memory size can vary
between sockets.
SDRAM
1. The DIMM slot has two notch, so the
DIMM memory module can only fit in
one direction.
3. Close the plastic clip at both edges of the DIMM slots to lock the DIMM module.
Reverse the installation steps when you wish to remove the DIMM module.
2. Insert the DIMM memory module
vertically into the DIMM slot. Then
push it down.
M When STR/DIMM LED is ON, do not install/remove SDRAM from socket.
M Please note that the DIMM module can only fit in one direction due to the two
notches. Wrong orientation will cause improper installation. Please change
the insert orientation.
