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 the
system’s components.
CPU Processor Installation
This mainboard supports Intel®Pentium®4 processors using a Socket 775. Before building
your system, we suggest you to visit the Intel website and review the processor
installation procedures. http://www.intel.com
CPU Socket 775 Configuration Steps:
1. Locate the CPU socket 775 on your
mainboard and nudge the lever away
from the socket as shown. Then lift
the lever to a 140-degree angle (A).
Next, lift up the iron cover (B).
2. There are two distinctive marks
located near the corners of the socket
on the same side as the lever as shown
(C). Match these marks with the marks
on the CPU and carefully lower the
CPU down onto the socket (D).
3. Replace the iron cover and then
lower the lever until it snaps back into
position (E). This will lock down the
CPU (F).
4. Smear thermal grease on the top of the CPU. Lower the
CPU fan onto the CPU/CPU socket and secure it using the
attachments or screws provided on the fan. Finally, attach
the fan power cord to the JCFAN1 header.
Attention: DO NOT touch the CPU pins due to they are sensitive
and easily to be damaged. Also, make sure that you have completed
all installation steps before power-on the system. Finally,
double-check that the heatsink is properly installed and make sure
that the CPU fan power cord is securely attached (cooling problems
may cause overheating and lead to damage the CPU and other
sensitive components).

SDRAMs and support a total memory capacity of 2 GB.
Memory Setup Steps:
The following instructions explain how to set memories onto the DIMM sockets for this
mainboard.
Attention: We strongly recommend you that attach a cooling fan
on top of the CPU and also attach the fan power cord onto the
mainboard JCFAN1 header, to avoid your CPU damaged due to
high temperatures.
In general, the fan power cord is designed and should be attached
with a specific direction. The black wire of the fan power cord is
Ground and should be attached onto the header pin-1.

1. Pull the white plastic tabs at both ends of the socket away.
2. Align a memory on the socket such that the notch on the memory matches the break
on the socket.
3. Lower the memory vertically into the socket and press firmly by using both thumbs
until the memory snaps into place.
4. Repeat steps 1, 2 & 3 for the remaining memory and DIMM sockets setup.

Chapter 2. BIOS Setup
Introduction
This section describes PHOENIX-AWARD™ BIOS Setup program which resides in the BIOS
firmware. The Setup program allows users to modify the basic system configuration. The
configuration information is then saved to CMOS RAM where the data is sustained by
battery after power-down.
The BIOS provides critical low-level support for standard devices such as disk drives, serial
ports and parallel ports. As well, the BIOS control the first stage of the boot process,
loading and executing the operating system.
The PHOENIX-AWARDTM BIOS installed in your computer system’s ROM is a custom version
of an industry standard BIOS. This means that it supports the BIOS of Intel®based
processors.
This version of the PHOENIX-AWARDTM BIOS includes additional features such as virus and
password protection as well as special configurations for fine-tuning the system chipset.
The defaults for the BIOS values contained in this document may vary slightly with the
version installed in your system.
Key Function
In general, you can use the arrow keys to highlight options, press <Enter> to select, use
the <PgUp> and <PgDn> keys to change entries, press <F1> for help and press <Esc>
to quit. The following table provides more detail about how to navigate within the BIOS
Setup program.
Attention
In general, power cords are designed and should be attached
with a specific direction. The black wire of the power cord is
Ground and should be attached onto the header location of
Ground.
