Static Electricity Precautions
Components on this mainboard can be damaged by static
electricity. Take the following precautions when unpacking the
mainboard and installing it in a system.
1. Keep the mainboard and other components in their original
static-proof packaging until you are ready to install them.
2. During installation, 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. Handle the mainboard carefully by the edges. Avoid touching
the components unless it is absolutely necessary. During
installation put the mainboard on top of the static -protection
packaging it came in with the component side facing up.
Pre-Installation Inspection
1. Inspect the mainboard for damage to the components and
connectors on the board.
2. If you suspect that the mainboard has been damaged, do not
connect power to the system. Contact your mainboard vendor
and report the damage.

Chapter 2
Mainboard Installation
To install this mainboard in a system, follow the procedures in this
chapter:
Identify the mainboard components
Install a CPU
Install one or more system memory modules
Verify that any jumpers or switches are set correctly
Install the mainboard in a system chassis (case)
Connect any extension brackets or cables to the mainboard
connector headers
Install any other devices and make the appropriate connections to
the mainboard connector headers.
Note:
1. Before installing this mainboard, make sure jumper JP4 set to

Install A CPU
This mainboard has a Socket-A which supports AMD K7
processors.
To ensure reliability, ensure that your processor has a
heatsink/cooling fan assembly.
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 notes the processors that are currently supported
by this mainboard.
Athlon: 650 MHz~1.4 GHz, FSB: 200 MHz, 266 MHz
Duron: 550~950 MHz, FSB: 200 MHz
Installing a Socket-462 Processor
A processor installs 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.

Socket-462
Pin-1 Corner

Mainboard User’s Manual

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
use the mainboard, and you can only use one of the both
SDRAM and DDR SDRAM at the same time .
DDR SDRAM provides 800 MBps or 1 GBps data transfer
depending on whether the bus is 100 MHz or 133 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 2.5V unbuffered
DIMM module reather than the 168-pin 3.3V unbuffered DIMMs
used by SDRAM.
For this mainboard, the maximum memory size is 1GB.
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.
The table below lists the model chips of DDR that we have
tested.

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: Keyboard Power On Selector
If you enable the keyboard power on feature, you can use hot keys
on your keyboard as a power on/off switch for the system.
Note: The system must provide 1A on the +5VSB (+5V Standby)
signal before using the Keyboard Power On function.

Jumper JP4: Clear CMOS Memory
Use this jumper to 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 power cables from
the mainboard and then move the jumper cap into the CLEAR
setting for a few 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_PWR1 connector on the mainboard.
If there is a cooling fan installed in the system chassis, connect the
cable from the cooling fan to the SYSFANfan 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 FP_AUDIO header on the
mainboard. See the illustrations below for the guide to the FP1 and
FP_AUDIO headers pin assignments.
