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 Pin 1 of CPU is marked by the
yellow corner or cut edge on the CPU. Match Pin 1 of
Socket 478 and Pin 1 of CPU.
3. Pull up the lever of Socket 478 to let the CPU in and press
the lever down to lock the CPU.
4. Make sure that Pin 1 of Socket 478 is matching with Pin 1 of
CPU.
5. Make sure that all CPU pins are completely in socket before
pressing down the socket lever.

1.5.2 CPU Fan Installation with P4 Fan Base
1. P4 CPU Fan is typically designed with 4 latches and mounted
with a thick heatsink. Please do not use other type of CPU fan
which cannot match the P4 Fan base on board.
2. Install the P4 CPU fan into the Fan base in such a way that
the 4 latches of the CPU Fan match with the 4 Supporters of
the CPU Fan Base.
3. Press down the latches to lock CPU Fan to the Fan Base.
4. Then connect the Fan Power Cable to one of the Fan con-
nectors on board.
5. Make sure that the Fan Power Cable is correctly connected
to Fan Connector.

This motherboard supports a maximized 2GB DDR
SDRAM. It provides two184-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 the module
vertically to fit it into place.
3. The Mounting Holes and plastic tabs should fit over the
edge and hold the DDR memory modules in place.
Warning: Be sure to turn off system power whenever to insert or
remove a Memory Module. Otherwise, the power will damage the
module or even the system.

1.7.1.3 Serial Interface Port: COM1
The serial interface port is sometimes referred 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 computer systems together . If you like to transfer
the contents of your hard disk to another system, it can be
accomplished with 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 is a 25-pin, DB 25 connector.
1.7.1.5 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.
