Static Electricity Precautions
Static electricity could damage components on this motherboard.
Take the following precautions while unpacking this motherboard
and installing it in a system.
1. Don’t take this mainboard and components out of their
original static-proof package until you are ready to install
them.
2. While installing, please wear a grounded wrist strap if
possible. If you don’t have a wrist strap, discharge static
electricity by touching the bare metal of the system chassis.
3. Carefully hold this motherboard by its edges. Do not touch
those components unless it is absolutely necessary. Put this
motherboard on the top of static-protection package with
component side facing up while installing.
Pre-Installation Inspection
1. Inspect this motherboard whether there are any damages to
components and connectors on the board.
2. If you suspect this mainboard has been damaged, do not
connect power to the system. Contact your motherboard
vendor about those damages.

Notice:
1. Owing to Microsoft’s certifying schedule is various to every
supplier, we might have some drivers not certified yet by
Microsoft. Therefore, it might happen under Windows XP that
a dialogue box (shown as below) pop out warning you this
software has not passed Windows Logo testing to verify its
compatibility with Windows XP. Please rest assured that our
RD department has already tested and verified these drivers.
Just click the “ContinueAnyway” button and go ahead the
installation.
2. USB 2.0 Driver Limitations:
2-1.The USB 2.0 driver only supports Windows XP and
Windows 2000.
2-2.If you connect a USB 2.0 hub to the root hub, plugging
USB devices into this hub, the system might not success
fully execute certain USB devices’ connection because it
could not recognize these devices.
Currently, we are working on such limitations’solution.As soon
as the solution is done, the updated USB drive will be released to
our website: www.pcchips.com.tw for your downloading.

Installing the Processor
This motherboard has a LGA775 socket for the latest Intel
Pentium 4/Celeron processors. When choosing a processor,
consider the performance requirements of the system. Perfor-
mance is based on the processor design, the clock speed and
system bus frequency of the processor, and the quantity of internal
cache memory and external cache memory.
CPU Installation Procedure
Follow these instructions to install the CPU:
A. Unload the cap
•Use thumb & forefinger to hold the
lifting tab of the cap.
•Lift the cap up and remove the cap
completely from the socket.
B. Open the load plate
•Use thumb & forefinger to hold the
hook of the lever, pushing down and
pullingasideunlockit.
•Lift up the lever.
•Use thumb to open the load plate.

Be careful not to touch the contacts.
C. Install the CPU on the socket
•Orientate CPU package to the socket.
Make sure you match triangle marker
to pin 1 location.
D. Close the load plate
•Slightly push down the load plate onto
the tongue side, and hook the lever.
•CPU is locked completely.
E. Apply thermal grease on top of the CPU.
F. Fasten the cooling fan supporting base
onto the CPU socket on the
motherboard.
G. Make sure the CPU fan is plugged to
the CPU fan connector. Please refer to
the CPU cooling fan user’s manual for
more detail installation procedure.
Note: To achieve better airflow rates and heat dissipation, we
suggest that you use a high quality fan with 3800 rpm at least.
CPU fan and heatsink installation procedures may vary with the
type of CPU fan/heatsink supplied. The form and size of fan/
heatsink may also vary.

Chapter2:MotherboardInstallation
Installing Memory Modules
This motherboard accommodates two 184-pin 2.5V DIMM
sockets (Dual Inline Memory Module) for unbuffered DDR 400/
333/266/200 memory modules (Double Data Rate SDRAM) and
maximum 2.0 GB installed memory.
DDR SDRAM is a type of SDRAM that supports data transfers
on both edges of each clock cycle (the rising and falling edges),
effectively doubling the memory chip’s data throughput. DDR
DIMMs can synchronously work with 400/333/266/200 MHz
memory and provide 3.2 GB/s, 2.7 GB/s, 2.1 GB/s and 1.6GB/s
data transfer rate.

Memory Module Installation Procedure
These modules can be installed with up to 2 GB system memory.
Refer to the following to install the memory module.
1. Push down the latches on both sides of the DIMM
socket.
2. Align the memory module with the socket. There is a
notch on the DIMM socket that you can install the
DIMM module in the correct direction. Match the cutout
on the DIMM module with the notch on the DIMM
socket.
3. Install the DIMM module into the socket and press it
firmly down until it is seated correctly. The socket latches
are levered upwards and latch on to the edges of the
DIMM.
4. Install any remaining DIMM modules.
