Preparing Your Computer
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.

Introduction
Hardware Installation Process
To set up your computer, you must complete the following steps:
English
Step 1- Install the Central Processing Unit (CPU)
Step 2- Install memory modules
Step 3- Install expansion cards
Step 4- Install I/O Peripherals Cables
Step 4
Step 1
Step 2
Step 4
Step 4
Step 3
Step 1: Install the Central Processing Unit (CPU)
Before installing the processor, adhere to the following warning:
1. Please make sure the CPU type is supported by the motherboard.
2. The processor will overheat without the heatsink and/or fan, resulting in permanent
irreparable damage.
3. 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.
4. Apply thermal grease between the processor and cooling fan.
5. Never run the processor without the heatsink properly and firmly attached. Permanent
damage will result.
6. 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,
Memory, Cards…etc.
HT functionality requirement content :
Enabling the functionality of Hyper-Threading Technology for your computer system
requires all of the following platform components:
- CPU: An Intel® Pentium 4 Processor with HT Technology
- Chipset: A SiS® Chipset that supports HT Technology
- BIOS: A BIOS that supports HT Technology and has it enabled
- OS: An operation system that has optimizations for HT Technology

Step 1-1: CPU Installation
English
Socket
Actuation
Lever
Figure 1.
Pull the rod to the 90-degree directly.
Figure 2.
Locate Pin 1 in the socket and look for a (golden) cut edge on the
CPU upper corner. Insert the CPU into the socket. (Do not force the
CPU into the socket.) Then move the socket lever to the locked
position while holding pressure on the center of the CPU.
Step 1-2: CPU Cooling Fan Installation
Figure 1.
Apply the thermal tape(or grease) to provide better heat conduction
between your CPU and cooling fan.
Figure 2.
Fasten the cooling fan supporting-base onto the CPU socket on the
motherboard.
Figure 3.
Make sure the CPU fan is plugged to the CPU fan connector, than
install complete.

Step 2: Install Memory Modules
English
The motherboard supports DDR memory modules, whereby BIOS will automatically detect memory
capacity and specifications. Memory modules are designed so that they can be inserted only in one
direction. The memory capacity used can differ with each slot.
Before installing the memory modules, please comply with the following conditions:
1. Please make sure that the memory used is supported by the motherboard. It is
recommended that memory of similar capacity, specifications and brand be used.
2. Before installing or removing memory modules, please make sure that the computer
power is switched off to prevent hardware damage.
3. Memory modules have a foolproof insertion design. A memory module can be installed
in only one direction. If you are unable to insert the module, please switch the direction.
Notch
DDR
1. The DIMM socket has a notch, so the DIMM memory
module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM
socket. Then push it down.
3. Close the plastic clip at both edges of the DIMM sockets
to lock the DIMM module.
Reverse the installation steps when you wish to
remove the DIMM module.

Step 3: Install AGP Card
1. Read the relate AGP card's instruction document before install the AGP card into the computer.
2. If your AGP card has "AGP 4X/8X(1.5V) notch"(show below), please make sure your AGP card is
AGP 4X/8X(1.5V).
AGP 4X/8X notch
3. Please carefully pull out the small white-drawable bar at the end of the AGP slot when you try to
install/uninstall the AGP card. Please align the AGP card to the onboard AGP slot and press firmly
down on the slot. Make sure your AGP card is locked by the small white-drawable bar.
Step 4: Install I/O Peripherals Cables

PS/2 Keyboard and PS/2 Mouse connector
To install a PS/2 port keyboard and mouse, plug the mouse to the upper port (green) and the
keyboard to the lower port (purple).
Parallel port (LPT)
The parallel port allows connection of a printer, scanner and other peripheral devices.
Serial port (COMA/COMB)
Mouse and modem etc. can be connected to Serial port.
USB port
Before you connect your device(s) into USB connector(s), please make sure your device(s) such
as USB keyboard, mouse, scanner, zip, speaker...etc. Have a standard USB interface. Also make
sure your OS supports USB controller. If your OS does not support USB controller, please contact
OS vendor for possible patch or driver upgrade. For more information please contact your OS or
device(s) vendors.
