FCC-B Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a class
B digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equip-
ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor-
dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.
Notice 1
The changes or modifications not expressly approved by the party respon-
sible for compliance could void the user’s authority to operate the equipment.
Notice 2
Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

PC Alert™ 4
The PC AlertTM 4 is a utility you can find in the CD-ROM disk. The utility
is just like your PC doctor that can detect the following PC hardware status
during real time operation:
Ømonitor CPU & system temperatures
Ømonitor fan speeds
Ømonitor system voltages
If one of the items above is abnormal, the program main screen will be
immediately shown on the screen, with the abnormal item highlighted in red.
This will continue to be shown until the condition returns to the normal status.
Users can use the Adjusting Keys to change the minimum and maximum
threshold of each item for the system to send out a warning message. Click
Temperature to select the temperature modes of either Fahrenheit (oF) or Cel-
sius (oC). The PC Alert4 icon on the Status Area will show the current CPU
temperature.

Setup
This chapter tells you how to install the CPU, memory
modules, and expansion cards, as well as how to setup the jump-
ers on the mainboard. Also, it provides the instructions on con-
necting the peripheral devices, such as the mouse, keyboard,
etc.
While doing the installation, be careful in holding the com-
ponents and follow the installation procedures.

Hardware Setup
Central Processing Unit: CPU
The mainboard supports AMD®Athlon™, Athlon™ XP and Duron™
processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A for easy CPU installation. When you are installing the CPU, make
sure the CPU has a heat sink and a cooling fan attached on the top to
prevent overheating. If you do not find the heat sink and cooling fan, contact
your dealer to purchase and install them before turning on the computer.
As processor technology pushes to faster speeds and higher performance, ther-
mal management becomes increasingly crucial when building computer
systems. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified thermal
requirements.
AMD Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz
and above requires a LARGER heatsink and fan. You also need to add ther-
mal grease between the CPU and heatsink to improve heat dissipation. Then,
make sure that the CPU and heatsink are securely fastened and in good con-
tact with each other. These are needed to prevent damaging the processor and
ensuring reliable operation. If you want to get more information on the proper
cooling, you can visit AMD’s website for reference.
WARNING! Thermal Issue for CPU
CPU Core Speed Derivation Procedure
CPU Clock multiplied by Core/Bus ratio equals the CPU core speed.
For example:
If CPU Clock = 100MHz
Core/Bus ratio = 14
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 14
= 1.4 GHz

1. Please turn off the power and
unplug the power cord before
installing the CPU.
2. Pull the lever sideways away
from the socket. Make sure
to raise the lever up to a 90-
degree angle.
3. Look for the gold arrow. The
gold arrow should point to-
wards the lever pivot. The
CPU can only fit in the cor-
rect orientation.
4. If the CPU is correctly
installed, the pins should be
completely embedded into the
socket and can not be seen.
Please note that any violation
of the correct installation pro-
cedures may cause permanent
damages to your mainboard.
5. Press the CPU down firmly
into the socket and close the
lever. As the CPU is likely to
move while the lever is being
closed, always close the lever
with your fingers pressing
tightly on top of the CPU to
make sure the CPU is prop-
erly and completely embed-
ded into the socket.
