Hardware Installation
This section will assist you in quickly installing your system hardware. Wear a wrist ground strap
before handling components. Electrostatic discharge may damage your system components.
CPU Processor Installation
This mainboard supports Intel® Pentium® 4 processors using a Socket 478. Before building your
system, we suggest you visit the Intel website and review the processor installation procedures.
http://www.intel.com
CPU Socket 478 Configuration Steps:
1. Locate the CPU socket on your mainboard and nudge the lever away from the socket. Then lift
the lever to a 90-degree angle.
2. On the socket, locate the corner that has the pin-1 receptor. This corner will be near the end of
the lever on the socket. Match the dot on the CPU with the pin-1 receptor on the socket and
lower the CPU onto the socket. The bottom of the CPU should be flush with the face of the
socket.
3. Lower the lever until it snaps back into position. This will lock down the CPU.
4. Smear thermal grease on top of the CPU. Lower the CPU fan onto the CPU and use the clasps
on the fan to attach it to the socket. Finally, extend the power cable from the fan and insert It
onto the CPUFAN adapter.

Attention: Before starting the system
Please check the installation completely before starting the system.
Verify that the heatsink is properly installed and make sure the CPU
fan is working. Overheating can damage the CPU and other
sensitive components.

Memory Installation
The mainboard contains 3 sockets, which use 184--pin DDR SDRAM with a total memory capacity
of up to 2 GB. You can install unbuffered & non-ECC DDR333/ 266 (PC2700/ 2100) SDRAM. It
supports DDR266 when installed with CPUs that have clcok speeds of 100 MHz. It supports
DDR266/333 when installed with CPUs that have clock speed of 133 MHz. It supports DDR400
when installed with CPUs that have clock speed of 200 MHz (it’s by overclock).

PX865PEL-800
If you are using DIMM2 and DIMM3 simultaneously, you must use single-sided memory
modules with the total memory used by these two sockets not exceeding 1 GB.
If you will be using double-sided DDR DIMM modules, you can only install up to 2 modules.
When using 2 double-sided DDR DIMM modules, we recommend that you them install into
DIMM1 and DIMM2.
If you are installing only 1 double-sided DDR DIMM module, we recommend that you install
it into either DIMM1 or DIMM2.

RAM Module Installation:
1. Pull the white plastic tabs on each side of the slot away from the slot.
2. Match the notch on the button of the RAM module with the corresponding pattern in the
DIMM slot. This ensures that the module is inserted properly.
3. Lower the RAM module into the DIMM Slot and press firmly using both thumbs until the
module snaps into place.
4. Repeat steps 1 & 2 for the remaining RAM modules.

Line In
This mainboard supports Super 5.1 Channel Audio effects which
turns your standard Speaker Out, Lin In, Mic In audio connectors
into a 6 channel audio system. See Appendix II for more information.
1. Speaker Out is used to connect to speakers or
headphones. If the Super 5.1 driver is installed the Speaker
Out becomes the Front Speaker.
2. Line In can be connected to an external CD player, Tape
player or other audio devices for audio input. If the Super 5.1
driver is installed Line In becomes the Rear Speaker.
3. Mic In is used to connect to a microphone. If the Super
5.1 driver is installed the Mic In becomes the Subwoofer/
Center out.

HD LED (Hard Drive LED Connector)
This connector can be attached to an LED on the front panel of a computer case. The LED will
flicker during disk activity. This disk activity only applies to those IDE drives directly attached to the
system board.
RST (Reset Button)
This connector can be attached to a momentary SPST switch. This switch is normally left open.
When closed it will cause the mainboard to reset and run the POST (Power On Self Test).
PWR-LED (Power LED Connector)
This connector can be attached to an LED on the front panel of a computer case. The LED will
illuminate while the computer is powered on.
PWR ON (Power Button)
This connector can be attached to a front panel power switch. The switch must pull the Power Button
pin to ground for at least 50 ms to signal the power supply to switch on or off (the time required is
due to internal debounce circuitry on the system board). At least two seconds must pass before the
power supply will recognize another on/off signal.
PWRLED (3-Pin Power LED )
If there is a 3-pin power LED cable on the front panel of a computer case. You can attach it to the
3-pin power LED connector.
SPEAKER (Speaker Header)
A front panel speaker can be connected to this connector. When you boot your computer, the speaker
sounds a short “beep”. If there is something wrong during the Power On Self-Test, the speaker
sounds “irregular beep” to warning you.
