processors. The Socket-A processor’s front-side bus speed is
266MHz.
This mainboard has aKM266 chipset that supports one 4X AGP
slot for highly graphics display, 100/133 MHz DDR, and Ultra
DMA ATA100/133 function to provide outstanding high system
performance under all types of system operations. It supports the
built-in AC97 Codec, and the 128-bit 2D/3D AGP Graphics
Acceleratorwith 32MB frame buffer, supporting AGP 4X
266MHz mode up to 1GB/s bandwidth, which provides a direct
connection between the graphics sub-system and memory so that
the graphics do not have to compete for processor time with other
devices on the PCI bus. There is a full set of I/O Ports including
PS/2 keyboard and mouse ports, one serial port, one onboard VGA
port, one parallel port, and maximum six USB2.0 ports –four
back-panel ports and onboard USB header USB3 providing two
extra ports by connecting the Extended USB Module to the
mainboard.

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

LAN Port
(optional) Connect an RJ-45 jack to the LAN port to
connect your computer to the Network.
USB Ports Use the USB ports to connect USB devices.
Note: The lower USB port located beside the
VGA port is shared with the READER1
connector.
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.
Installing the Processor
This mainboard has a Socket 462 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.

10
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 (CPUFAN1) on the
mainboard.
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.
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.
DDR1
DDR2

11
Installation Procedure
These modules can be installed with up to 2 GB 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.
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.
