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

Installing Memory Modules
This motherboard accommodates two 184-pin 2.5V DIMM
sockets (Dual Inline Memory Module) for unbuffered DDR266/
200 memory modules (Double Data Rate SDRAM), and maxi-
mum 2.0GB 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 200 MHz or 266 MHz
memory bus, providing 1.6 GB/s or 2.1 GB/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.
DDR1 DDR2

Chapter2: Motherboard Installation
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.
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.

Jumper Settings
Connecting two pins with a jumper cap is SHORT; removing a
jumper cap from these pins, OPEN.
JBAT1: Clear CMOS Jumper
Use this jumper to clear the contents of the CMOS memory. You
may need to clear the CMOS memory if the settings in the Setup
Utility are incorrect and prevent your motherboard from operating.
To clear the CMOS memory, disconnect all the power cables from
the motherboard and then move the jumper cap into the CLEAR
setting for a few seconds.
