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 AMD®GeodeTM NX processors using a Socket A (Socket 462 Pin package).
Before building your system, we suggest you visit the AMD website and review the processor
installation procedures. http://www.amd.com
CPU Socket A 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 have a cut-corner
on the rectangular shaped pattern of pin holes on the socket.
Match the corner 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.

Memory Installation: DIMM
The K7I741CX provides one DIMM socket. The socket allows you to install 184-pin, non-ECC &
unbuffered DDR 333 (PC2700)/ DDR 266 (PC2100) SDRAM that supports it to install a total
memory capacity of 1 GB.
Attention
DO NOT touch the CPU pins in case they are damaged. Also, make sure that
you have completed all installation steps before powered on the system.
Finally, double-check that the cooling fan is properly installed and the CPU
fan power cord is securely attached, in case your CPU and other sensitive
components are damaged because of high temperature
s
.
Attention
You can avoid damaging your CPU due to high temperatures with proper
cooling equipment. It is recommended that attach a cooling fan on top of
your CPU. Use the CPUFAN header to attach the fan cord.
On most fan power cord, the black wire of the fan cable is the “ground” and
should be attached to pin-1 of the heade

Memory Installation Steps:
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.

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
