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. efore installing this mainboard, make sure jumper JP3 is set
to Normal, the default setting. See this chapter for information
on locating JP3 and the setting options.
2. Never connect power to the system during installation. Doing
so may damage the mainboard.

Mainboard Components
Use the diagram below to identify the major components on the
mainboard.
Note: Any jumpers on your mainboard that do not appear
in this illustration are for testing only.

2: Mainboard Installation
Install A CPU
This mainboard has a Socket 370 which supports PPGA/FCPGA
Celeron and FCPGA Pentium III processors.
o ensure reliability, ensure that your processor has a
heatsink/cooling fan assembly.
Do not try to install a Socket 7 processor in the Socket-370. A
Socket 7 processor such as the Pentium-MMX, or the AMD K5/K6
does not fit in the Socket 370.
The following list notes the processors that are currently supported
by this mainboard.
PPGA/FCPGA Celeron: 300~700 MHz, FS : 66 MHz
FCPGA Pentium III “Coppermine”: 500~1130MHz, FS :
100MHz, 133MHz
Installing a Socket-370 Processor
A processor installs into the ZIF (Zero Insertion Force) Socket-370
on the mainboard.
1. Locate the Socket-370 and FAN1. 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.

Socket-370
FAN1

Mainboard User’s Manual
3. On the Socket-370, identify the Pin-1 corner. The Pin-1 corner
is at the end of the locking lever when it is 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 FAN1.
Install Memory
The mainboard has two DIMM sockets for system memory
modules. You must install at least one memory module in order to
use the mainboard. You must install the first memory module in
the DIMM1 socket to provide shared memory to the onboard
VGA display circuitry.
For this mainboard, you must use 168-pin, 3.3V unbuffered
SDRAM memory modules. If the installed CPU uses a 100 MHz
system bus, you must use PC100/PC133 memory. If the installed
CPU uses a 66 MHz system bus, you must use PC66/PC100
memory. You can install any size memory module from 16M to
512M , so the maximum memory size is 2 x 512M = 1 G .
The edge connectors on the memory modules have cut outs, which
coincide with spacers in the DIMM sockets so that memory
modules can only be installed in the correct orientation.

DIMM1
DIMM2

2: Mainboard Installation
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 umper 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 JP2: Wake On LAN Selector
This controls the LAN Wake Up feature where the system will
wake up in response to a signal over a LAN it is connected to.
Note: The system must provide 1A on the +5VSB (+5V Standby
signal in order for this feature to work.
Function Jumper Setting
Disable Short Pins 1-2
Enable Short Pins 2-3
Jumper JP3: 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.

2: Mainboard Installation
Install the Mainboard
Install the mainboard in a system chassis (case). The board is a
aby-AT size mainboard with a set of I/O ports. You can install
this mainboard in any AT 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 PWR2/
PWR1 AT/ATX Power connector on the mainboard. If there is a
cooling fan installed in the system chassis, connect the cable from
the cooling fan to the FAN2 fan power connector on the
mainboard. Connect the case switches and indicator LEDs to the
J2 switch and LED connector header. See the illustration below for
a guide to the J2 connector pin assignments.

Install the Extension Brackets
The extension brackets are used to connect features on the
mainboard to external connectors that can be attached to the
system chassis. Follow the steps below to install the extension
brackets.
Note: All the ribbon cables used on the extension brackets have a
red stripe on the Pin-1 side of the cable.
Audio Ports and Game/MIDI Port xtension Bracket
This bracket provides three audio jacks for stereo line in, stereo
line out and microphone. In addition it has a 15-pin D-connector
which can be used by either a joystick or a MIDI device.
If you are using a four channel speaker system, channel one and
two are output through the Stereo Line-out, and the rear speaker
channels three and four are output through Stereo Line-in.
1. On the mainboard, locate the SOUND1 audio header for this
bracket.
2. Plug the cable from the bracket into the audio header.
3. In the system chassis, remove a blanking plate from one of the
expansion slots and install the extension bracket in the slot.
Use the screw that held the blanking plate in place to secure
the extension bracket.

port –PRN1 (25pins). On this mainboard, the second serial port is
reserved for the Fax/Modem so you can only connect one of the
serial ports to the manboard header COM1.
1. On the mainboard, locate the headers COM1 and PRN1 for
this bracket.
2. Plug the serial cable into COM1 and the parallel cable into
PRN1.
3. In the system chassis, remove a blanking plate from one of the
expansion slots and install the extension bracket in the slot.
