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 “Continue Anyway” button and go ahead the
installation.
2. US 2.0 Driver Limitations:
2-1 The US 2.0 driver only supports Windows XP and
Windows 2000.
2-2 If you connect a US 2.0 hub to the root hub, plugging US
devices into this hub, the system might not successfully
execute certain US 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 US drive will be released to
our website: www.pcchips.com.tw for your downloading.

Installing t e Processor
This mainboard has a Socket 478 processor socket. When choosing
a processor, consider the performance requirements of the system.
Performance 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:
1. Unhook the CPU socket’s locking lever by pulling
it away from socket and raising it to the upright
position.
2. Match the pin 1 corner of CPU socket to the one of
processor, and insert the processor into the socket.
Do not use force.
3. Push the locking lever down and hook it under the
latch on the edge of socket.
4. Apply thermal grease to the top of the CPU.
5. Lower the CPU fan/heatsink unit onto the CPU and
CPU socket, and then use the retention module
clamps to snap the fan/heatsink into place.
6. Plug the CPU fan power cable into the CPU
cooling fan power supply (CPU_FAN) on the
mainboard.

Mainboard User’s Manual
Installing Memory Modules
This mainboard accommodates two 168-pin 3.3V unbuffered
Synchronous Dynamic Random Access Memory (SDRAM) and
two 184-pin 2.5V unbuffered Double Data Rate SDRAM (DDR
SDRAM) Dual Inline Memory Module (DIMM) sockets,
supporting 133 MHz SDRAM / 266 MHz DDR SDRAM.
The SDRAM DIMMs and DDRs can synchronously work with
100 MHz or operates over a 266 MHz system bus.
You must install at least one memory module in order to work out
this mainboard, either SDRAM or DDR SDRAM, but you can’t
use them simultaneously.
SDRAM provides 800 M /s or 1 G /s data transfer rate depending
on whether the bus is 100 MHz or 266 MHz. DDR SDRAM
doubles the rate to 1.0 G /s and 2.1 G /s by transferring data on
both the rising and falling edges of the clock. DDR SDRAM uses
additional power and ground lines and requires 184-pin 2.5V
unbuffered DIMM module.

2: Mainboard Installation
Installation Procedure
The mainboard accommodates two types of memory modules. You
must install at least one module in any of these sockets. You can
install each module up to 2G system memory.
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.
