The motherboard operates with Socket 478 for Intel P4TM
processor. The CPU should always has a Heat Sink and cooling fan
attached to prevent overheating.
CPU Installation Procedures: Socket 478
1. Pull the lever sideways away from the socket then raise
the lever to a 90-degree angle.
2. Locate Pin 1 in the socket and look for the white dot or
cut edge in the CPU. Match Pin 1 with the white dot or
cut edge then insert the CPU.
3. Press the lever down to complete the installation.
4. Make sure the spec of the cooling fan is good enough.
5. Make sure that the cooling fan and retention mechanism
assembly perfectly fits the heatsink and module
base, otherwise you can’t snap the hooks into the holes.

The motherboard supports a maximized 2GB memory. It provides
three 184-pin unbuffered DDR sockets. It supports 64MB to 1GB
DDR memory module.
DDR SDRAM Installation Procedures:
1. The DDR socket has a “Plastic Safety Tab” and the DDR
memory module has an asymmetrical notch”, so the
DDR memory module can only fit into the slot in one
direction.
2. Push the tabs out. Insert the DDR memory modules
into the socket at a 90-degree angle then push down
vertically to fit onto place.
3. The Mounting Holes and plastic tabs should fit over the
edge and hold the DDR memory modules in place.

1.7.1.3 Serial Interface Ports: COM1/COM2
The serial interface port is sometimes refered to as an
RS-232 port or an asynchronous communication port. Mice,
printers, modems and other peripheral devices can be
connected to a serial port. The serial port can also be used
to connect your computer system. If you like to transfer
the contents of your hard disk to another system, it can be
accomplished by serial port.
1.7.1.4 Parallel Interface Port
Unlike serial ports, parallel interface ports have been
standardized and should not present any difficulty interfacing
peripherals to your system. Sometimes called a Centronics
port, the parallel port is almost exclusively used with printers.
The parallel port on your system has a 25-pin, DB 25
connector.
1.7.1.5 Joystick / Midi Connector
You can connect a joystick or game pad to this connector.
1.7.1.6 Audio Port Connectors
Speaker out is a connector for Speakers or Headphones. Line
in is used for external CD player, Tape player, or other audio
devices. Mic is a connector for the microphones.
1.7.2 ATX Power Connectors: CN11/CN12/CN13/CN14
¡´This connector supports the power button on-board.
Using the ATX power supply, functions such as Modem
Ring Wake-Up and Soft Power Off are supported on this
motherboard . This power connector supports instant
power-on functionality, which means that the system will
boot up instantly when the power connector is inserted on
the board.
¡´ATX 4-pin power connector only support +12V voltage.

Important:
Before you switch on your power supply, please make
sure:
1. Memory Module installing is OK.
2. Power supply setting is OK.
3. AGP card for 2X or 4X device is OK.
Note:
1. Make sure that the ATX PIII power supply can take at
least 1Amp load on the 5Volt standby lead (5VSB).
2. When you use P4 power supply, you must plug CN12

airflow to go across the onboard heat sink(s) instead
of the expansion slots. Depending on the fan
manufacturer, the wiring and plug may be different.
The red wire should be positive, while the black should
be ground. Connect the fan’s plug to the board taking

ATX Power Switch (PW_BN)
The system power is controlled by a momentary switch
connected to this lead. Pushing the button once will switch
the system ON.
Power LED Lead (PW_LED)
The system power LED lights when the system power is on.
Speaker Connector (SPEAKER)
The speaker (onboard or offboard) provides error beep code
information during the Power Self-Test when the computer
cannot use the video interface. The speaker is not connected to
the audio subsystem and does not receive output from the audio
subsystem.
Hard Drive LED Connector (HD_LED)
This connector supplies power to the cabinet IDE activity LED.
Read and write activity by devices connected to the Primary or
Secondary IDE connectors will cause the LED to light up.
Reset Switch Lead (RESET)
The connector can be connected to a momentary SPST type
switch that is normally open. When the switch is closed, the
