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. Click
the “Continue Anyway” 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 successfully
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.

Static Electricity Precautions
Components on this mainboard can be damaged by static
electricity. Take the following precautions when unpacking the
mainboard and installing it in a system.
1. Keep the mainboard and other components in their original
static-proof packaging until you are ready to install them.
2. During installation, 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. Handle the mainboard carefully by the edges. Avoid touching
the components unless it is absolutely necessary. During
installation put the mainboard on top of the static-protection
packaging it came in with the component side facing up.
Pre-Installation Inspection
1. Inspect the mainboard for damage to the components and
connectors on the board.
2. If you suspect that the mainboard has been damaged, do not
connect power to the system. Contact your mainboard vendor
and report the damage.

Chapter 2
Mainboard Installation
To install this mainboard in a system, please follow these
instructions in this chapter:
 Identify the mainboard components

Audio Ports Use the three audio ports to connect audio
devices. The first jack is for stereo Line-In
signal. The second jack is for stereo Line-
Out signal. The third jack is for
Microphone.
Install Memory Modules
This mainboard accommodates two 184-pin 2.5V unbuffered
Double Data Rate SDRAM (DDR SDRAM) Dual Inline Memory
Module (DIMM) sockets, and supports up to 2.0 GB
of 200/266 MHz DDR SDRAM.
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 100 MHz or 133 MHz
memory bus.
12

DDR SDRAM provides 1.6 GB/s or 2.1 GB/s data transfer rate
depending on whether the bus is 100 MHz or 133 MHz.
DDR SDRAM uses additional power and ground lines and requires
184-pin 2.5V unbuffered DIMM module.

DDR2
Installation Procedure
These modules can be installed with up to 2 GB system memory.
Refer to the following to install the memory module.
Refer to the following to install the memory modules.
1. Push the latches on each side of the DIMM socket
down.
2. Align the memory module with the socket. The
DIMM sockets are keyed with notches and the
DIMMs are keyed with cutouts so that they can
only be installed correctly.
3. Check that the cutouts on the DIMM module edge
connector match the notches in the DIMM socket.
4. 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.
5. Install any remaining DIMM modules.

Jumper Settings
Jumpers are sets of pins connected together with jumper caps. The
jumper caps change the mainboard’s operation by changing the
electronic circuits on the mainboard. If we connect two pins with a
jumper cap, these pins are SHORT; if remove a jumper cap from
these pins, they are OPEN.

JP2
Jumper JP2: Clear CMOS Memory
This jumper can clear the CMOS memory. You may need to clear
the CMOS memory if the settings in the Setup Utility are incorrect
that your mainboard can’t operate. To clear the CMOS memory,
disconnect all the power cables, and then move the jumper cap into
the CLEAR setting for a few seconds.
