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

Hardware Setup
2-1
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
The mainboard provides a Socket A (Socket 462) to support the latest
AMD Athlon/Athlon XP processor series. To avoid the thermal issue* of
the CPU, please make sure that the CPU has a heatsink and a cooling fan
attachedonitstop.
CPUInstallationProcedure
To install the CPU, please follow the steps below:
1. Pull the lever sideways away
from the socket; then, raise it
up to a 90-degree angle.
2. Locate the cut edge on the CPU,
and point it towards the lever
pivot. Insert the pins of the CPU
directly into the holes on the socket.
3. Press the lever down to complete
the installation.
Note: The CPU is designed with the “corner pin” on the
two of the four corners; thus, it should only fit in one correctly
orientation as installing. In addition, with the weight of the
heatsink and cooling fan attached, you can insert the CPU into
the socket easily. DO NOT press the CPU down by force when
installing in wrong orientation, this would bend and damage

CPU Core Speed Derivation Procedure
If CPUClock = 100MHz
Core/Bus ratio = 14
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHzx14
= 1.4GHz
* Thermal issue for CPU
As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly crucial when building computer
system. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified
thermal requirements. AMD recommends the use of high performance
thermalinterfacematerial.
AMD Athlon/Athlon XP processors with a speed of 600MHz and above
require the LARGER heatsink and cooling fan. You also need to add thermal
grease between the CPU and heatsink to improve heat dissipation; then,
make sure that the CPU and the heatsink are securely fastened and in good
contact with each other. These are needed to prevent damaging the proces-
sor and ensuring reliable operation.
Please visit AMD’s website for more information.

Memory
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod-
ules rather than 168-pin DIMM modules used by SDR SDRAM. Two types of
DDRareavailableatthetimeofwriting:PC1600&PC2100.PC1600DDRSDRAM
running at 100MHz will produce about 1.6GB/s memory bandwidth. PC2100
running at 133MHz will produce 2.1GB/s memory bandwidth. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta-
tions and servers.

DDR Module Combination
You can install PC1600/PC2100 DDR SDRAM modules into the DDR
DIMM slots (DDR 1~3) in any combination as follows:
DDR Module Installation Procedure
1. The DDR DIMM has only one notch on the center of module.
The module will only fit in the right orientation.
2. Insert the DIMM memory module vertically into the DIMM
slot. Then push it in.
3. The plastic clip at each side of the DIMM slot will automatically
close.

Power Supply
ATX20-PinPowerConnector
This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plugs of the power supply is
inserted in the proper orientation and the pins are aligned. Then push down
the power supply firmly into the connector. The power connector supports
instant power on function which means that system will boot up immediately
when the power supply connector is inserted on the board.
The mainboard supports ATX power supply for the power system. Be-
fore inserting the power supply connector, always make sure that all compo-
nents are installed properly to ensure that no damage will be caused.
