Static Electricity Precautions
Static electricity could damage components on this mainboard.
Take the following precautions while unpacking this mainboard
and installing it in a system.
1. Don’t take this mainboard and components out of their original
static-proof package until you are ready to install them.
2. While installing, please wear a grounded wrist strap if
possible. If you don’t have a wrist strap, discharge static
electricity by touching the bare metal of the system chassis.
3. Carefully hold this mainboard by its edges. Do not touch those
components unless it is absolutely necessary. Put this
mainboard on the top of static-protection package with
component side facing up while installing.
Pre-Installation Inspection
1. Inspect this mainboard whether there are any damages to
components and connectors on the board.
2. If you suspect this mainboard has been damaged, do not
connect power to the system. Contact your mainboard vendor
about those damages.

I/O Ports
The illustration below shows a side view of the built-in I/O ports
on the mainboard.
Install CPU
This mainboard has a Socket-462 that supports AMD K7
processors.
To ensure reliability, ensure that your processor has a
heatsink/cooling fan asse bly.
Do not try to install a Socket-370/Socket-7 processor in the
Socket-462. A Socket-370/Socket-7 processor such as the PPGA
Celeron, FCPGA Pentium-III, Pentium-MMX, or the AMD K5/K6
does not fit in the Socket-462.
The following list indicates these processors are currently
supported by this mainboard.
Athlon XP: 1500+ ~ 1900+; FSB: 266 MHz
Athlon/Duron: 500M ~ 1.4GHz; FSB: 200 MHz, 266 MHz

Mainboard User’s Manual
Installing a Socket-462 Processor
Install a processor into the ZIF (Zero Insertion Force) Socket-462
on the mainboard.
1. Locate the Socket-462 and CPUFAN. Pull the locking lever
out slightly from the socket and raise it to the upright position.
2. On the processor, identify the Pin-1 corner by its beveled edge.
3. On the Socket-462, identify the Pin-1 corner. The Pin-1 corner
is at the top of the locking lever when it locked.
4. Match the Pin-1 corners and insert the processor into the
socket. No force is required and the processor should drop into
place freely.
5. Swing the locking lever down and hook it under the catch on
the side of the socket. This secures the CPU in the socket.
6. All processors should be installed with a combination heatsink/
cooling fan, connect the cable from the fan to the CPU fan
power connector CPUFAN.
Install Memory
The mainboard has two 168-pin/184-pin DIMM sockets for
SDRAM/DDR (Double Data Rate) SDRAM system memory
modules. You must install at least one memory module in order to
work out the mainboard, either SDRAM or DDR SDRAM, but
you can not use the si ultaneously.

Socket-462
Pin-1 Corner

2: Mainboard Installation
DDR SDRAM provides 800 MBps or 1 GBps data transfer
depending on whether the bus is 100 MHz or 266 MHz. It doubles
the rate to 1.6 GBps and 2.1 GBps by transferring data on both the
rising and falling edges of the clock. DDR SDRAM uses additional
power and ground lines and requires 184-pin 2.5 unbuffered
DIMM module reather than the 168-pin 3.3 unbuffered DIMMs
used by SDRAM.
For this mainboard, the maximum memory size is 2GB.
The edge connectors on the memory modules have cut outs, which
coincide with spacers in the DIMM sockets so that memory
module can only be installed in the correct orientation.
To install a module, push the retaining latches at either end of the
socket outwards. Position the memory module correctly and insert
it into the DIMM socket. Press the module down into the socket so
that the retaining latches rotate up and secure the module in place
by fitting into notches on the edge of the module.

Setting Jumper Switches
Jumpers are sets of pins which can be connected together with
jumper caps. The jumper caps change the way the mainboard
operates by changing the electronic circuits on the mainboard. If a
jumper cap connects two pins, we say the pins are SHORT. If a
jumper cap is removed from two pins, the pins are OPEN.
Jumper JP1: Clear CMOS Memory
This jumper can clear the contents of the CMOS memory. You may
need to clear the CMOS memory if the settings in the Setup Utility
are incorrect and prevent your mainboard from operating. To clear
the CMOS memory, disconnect all the po er cables from the
mainboard and then move the jumper cap into the CLEAR setting
for a fe seconds.

Install the Mainboard
Install the mainboard in a system chassis (case). The board is an
ATX size mainboard with a twin-tier of I/O ports. You can install
this mainboard in an ATX case. Ensure that your case has an I/O
cover plate that matches the ports on this mainboard.
Install the mainboard in a case. Follow the instructions provided by
the case manufacturer using the hardware and internal mounting
points on the chassis.
Connect the power connector from the power supply to the
ATX_PWR connector on the mainboard.
If there is a cooling fan installed in the system chassis, connect the
cable from the cooling fan to the SYSFAN fan power connector on
the mainboard.
Connect the cable from the PC speaker to the SPK1 header on the
mainboard.
Connect the case switches and indicator LEDs to the SW1 header.
If there are a headphone jack or/and a microphone jack on the front
panel, connect the cables to the AUDIO1 header on the mainboard.
See the illustrations below for the guide to the SW1 and AUDIO1
headers pin assignments.

below.
Note: All the ribbon cables used on the extension brackets have a
red stripe on the Pin-1 side of the cable.
Extended USB Module
This module bracket has two USB ports for more USB devices
(USB port 3-4).
1. Locate the USB2 header on the mainboard.
2. Plug the bracket cable onto the USB2 header.
3. In the system chassis, remove a slot cover from one of the
expansion slots and install the extension bracket in the
opening. Use the screw that held the slot cover to secure the
extension bracket in the chassis.

Install Other Devices
Install and connect any other devices in the system following the
steps below.
Floppy Disk Drive
The mainboard ships with a floppy disk drive cable that can
support one or two drives. Drives can be 3.5” or 5.25” wide, with
capacities of 360K, 720K, 1.2MB, 1.44MB, or 2.88MB.
Install your drives and connect power from the system power
supply. Use the cable provided to connect the drives to the floppy
disk drive connector FDC.
IDE Devices
IDE devices include hard disk drives, high-density diskette drives,
and CD-ROM or D D-ROM drives, among others.
The mainboard ships with an IDE cable that can support one or
two IDE devices. If you connect two devices to a single cable, you
must configure one of the drives as Master and one of the drives as
Slave. The documentation of the IDE device will tell you how to
configure the device as a Master or Slave device. The Master
device connects to the end of the cable.
Install the device(s) and connect power from the system power
supply. Use the cable provided to connect the device(s) to the
Primary IDE channel connector IDE1 on the mainboard.
If you want to install more IDE devices, you can purchase a second
IDE cable and connect one or two devices to the Secondary IDE
channel connector IDE2 on the mainboard. If you have two
devices on the cable, one must be Master and one must be Slave.

Internal Sound Connections
If you have installed a CD-ROM drive or D D-ROM drive, you
can connect the drive audio cable to the onboard sound system.
On the mainboard, locate the two 4-pin connectors CD_IN1 and
CD_IN2. There are two kinds of connectors because different
brands of CD-ROM drives have different kinds of audio cable
connectors. Connect the cable to the appropriate connector.
Infrared Port
You can connect an infrared port to the mainboard. You can
purchase this option from third-party vendors.
1. Locate the infrared port IR1 header on the mainboard.
2. If you are adding an infrared port, connect the ribbon cable
from the port to the IR1 header and then secure the port to an
appropriate place in your system chassis.
