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 responsible
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

PC Alert III
The PC AlertTM III 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:
* monitor CPU & system temperatures
* monitor fan speed(s)
* monitor system voltage
* monitor chassis intrusion
Note: Items shown on PC Alert III vary depending on your systems
status.
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 con-
tinue to be shown until users disable the warning.

D-Bracket (Optional)
The D-Bracket which integrates four Diagnostic LEDs is optional.
Definitions of the D-Bracket LED signals are shown below.
The D-Bracket uses graphic signal display to help users understand
their system. Four LEDs embedded in the mainboard provide up to 16 combi-
nations of signals to debug the system. The 4 LEDs can debug all problems
that fail the system, such as VGA, RAM or other failures. This special feature
is very useful for the overclocking users. These users can use the feature to
detect if there are any problems or failures.

Hardware Setup
This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the components
and follow the installation procedures. For some components, if you install in
the wrong orientation, the components will not work properly.
Use a grounded wrist strap before handling computer components. Static
electricity may damage the components.

Central Processing Unit: CPU
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the cut edge. The cut
edge should point towards the
lever pivot. The CPU will only
fit in the correct orientation.
3. Hold the CPU down firmly, and
then close the lever to
complete the installation.
CPU Installation Procedures
Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.
WARNING!
The mainboard supports AMD®Athlon/Athlon XP/Duron processor.
The mainboard uses a CPU socket called Socket-462 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.
