Chapter 1
Static Electricity Precautions
1. Components on this mainboard can be damaged by static
electricity. Take the following precautions when unpacking the
mainboard and installing it in a system.
2. Keep the mainboard, and other components, in their original
static-proof packaging until you are ready to install them.
. During an installation, wear a grounded wrist strap if possible.
If you don’t have a wrist strap, frequently discharge any static
electricity by touching the bare metal of the system chassis.
4. Handle the mainboard carefully by the edges. Avoid touching
the components unless it is absolutely necessary. During the
installation lay the mainboard on top of the static-proof
packaging with the component side facing upwards.
5. Inspect the mainboard for any damage caused during transit.
Ensure that all the components that are plugged into sockets
are correctly seated.
6. If you suspect that the mainboard has been damaged, do not
apply power to the system. Contact your mainboard vendor
and report the damage.

Chapter 2
Mainboard Installation
To install this mainboard into your system, follow the procedures
in this chapter:
Identify the mainboard components
Install the correct processor
Install one or more memory modules
Verify that any jumpers or switches are at the correct setting
Install the mainboard in the system chassis
Install any extension cables to the mainboard headers
Install any other devices and make the appropriate connections
to the mainboard headers.
Note: Before installing the mainboard, you must ensure that the
Clear CMOS jumper JP1 is set to the Normal setting. See this
hapter for information lo ating JP1 and hanging the jumper
setting.
Note: Please donot use the AC power ord to onne t the system
ase to a power outlet until you have ompletely installed the
mainboard and omponents. In some ir umstan es, the power
management of the system might damage omponents and reate
unsafe onditions by allowing power to flow before the installation
is omplete,

Install the Mainboard
I/O Ports
The illustration below shows a side view of the I/O ports installed
on the mainboard.
Install the Processor
This mainboard has a Slot-1 that can be installed with any Slot-1
processor cartridge including the Pentium-II, Pentium-III and the
SEPP Celeron. It also has a Socket-370 that can be installed with
the FCPGA Coppermine, Celeron and Cyrix Joshua processor
them are shipped in a PPGA (Plastic Pin Grid Array) package.
To ensure reliability, ensure that your PPGA processor has a
heatsink/cooling fan assembly.
You can install a Slot-1 or a PPGA processor. You cannot install a
PPGA and a Slot-1 processor cartridge together. Take care that you
do not try to install a Socket-7 processor into the Socket-370. A
Socket-7 processor such as the Pentium-MMX, or the AMD
K5/K6 does not fit in the socket-370.

Chapter 2
Installing a Slot-1 Processor Cartridge
1. Locate Slot-1 and CP FAN1 on the mainboard.
2. The Slot-1 is installed with a cartridge holder. The upright
struts of the cartridge holder are folded down for shipping. Pull
the struts upwards so that they are in the upright position.
3. Insert the processor cartridge into the cartridge holder. Follow
the instructions given with your processor cartridge. The edge
connector on the cartridge has a notch so that it only fits into
the Slot-1 in the correct way.
4. Locate the cooling fan power supply CP FAN1. Connect the
cable from the processor cartridge cooling fan to CP FAN1.
5. On this mainboard, you can configure the processor by
entering the correct settings in the BIOS setup utility.

Install the Mainboard
Installing a Socket-370 Processor
The FCPGA Coppermine, Celeron or Cyrix Joshua processor
install into the ZIF (Zero Insertion Force) Socket-370 on the board.
1. Locate the Socket-370, CP FAN1, JP6 and JP7. Pull the
locking lever out from the socket and swing it to the upright
position.
2. On the Coppermine/Celeron/Joshua processor, identify the pin-
1 corner by noting that it has a slight bevel.
3. On the Socket-370, identify the pin-1 corner. The pin-1 corner
is on the same side as the locking lever, closest to the top of
the lever when it is in the locked position.
4. Match the pin-1 corners and insert the Celeron/Joshua
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 locks the Celeron/Joshua processor
in the socket.
6. Locate the jumpers JP6 and JP7. se these two jumpers to
select installed a Intel processor or a Cyrix Joshua processor.
The jumper settings are listed below.

7. If the processor is installed with a cooling fan assembly,
connect the cable from the fan to the CP fan power connector
CP FAN1.
Install Memor
The mainboard has three DIMM slots which can be installed with
memory modules. You must install at least one memory module in
order to use the mainboard.
For this mainboard, you must use 168-pin, 3.3V memory modules
installed with SDRAM memory chips. If you are using a processor
cartridge that runs on a 66/100 MHz system bus, you must use
memory that operates on a 66/100 MHz memory bus. If you are
using a processor cartridge that runs on a 133 MHz system bus,
you can use memory that operates on a 100 or 133 MHz memory
bus. You can install any size of memory module from 16 MB up to
256 MB, so the maximum memory size is 3 x 256 MB = 768 MB.
The edge connectors on the memory modules have cut outs, which
coincide with struts in the DIMM slots, so the memory modules
can only be installed in the correct way.
On the DIMM slot, pull the locking latches at either end of the
slots outwards. Position the memory module correctly and insert it
into the DIMM slot. Press the module down into the slot so that the
locking latches lever inwards and lock the module in place.

Set the Jumpers
Jumpers are sets of pins that 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 Memor
se 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.
