The motherboard operates with Socket 370 for Intel PIIITM
processor. The CPU should always has a Heat Sink and cooling fan
attached to prevent overheating.
CPU Installation Procedure: Socket 370
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 installation.
4. Make sure the spec of the heatsink is good enough.
5. Please lock the fan on CPU very carefully, or you
will damage the resistor array even circuit line
on the mainboard.

Module.(168 pin)
How to install a DIMM Module:
1. The DIMM socket has a “Plastic Safety Tab” and the DIMM
memory module has an asymmetrical notch”, so the
DIMM memory module can only fit into the slot in one
direction.
2. Push the tabs out. Insert the DIMM memory modules
into the socket at a 90-degree angle then push down
vertically so that it will fit into place.
3. The Mounting Holes and plastic tabs should fit over the
edge and hold the DIMM memory modules in place.

1.7.1.3 The Serial Interfaces: 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.

CN1 is the connector for CD-Audio Input signal. Please
connect it to CD-ROM CD-Audio output connector.
These connectors support cooling fans of 1Amp or
less. Orientate the fans so that the heatsink fins allow
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
into consideration the polarity of the this connector.
