PS/2 Mouse Use the upper PS/2 port to connect a PS/2
pointing device.
PS/2 Keyboard Use the lower PS/2 port to connect a PS/2
keyboard.
Parallel Port
(LPT1) Use LPT1 to connect printers or other
parallel communications devices.
COM1 Use the COM port to connect serial devices
such as mice or fax/modems. COM1 is
identified by the system as COM1.
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 near the
Parallel port is shared with the JUSBC
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 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.
9

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 connector on the
mainboard.
Installing 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 200/266/333 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 100MHz, 133MHz or
166MHz 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.
DIMM1
DIMM2
Installation Procedure
These modules can be installed with up to 2 GB system memory.
Refer to the following to install the memory module.
10

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.
