Introduction
This mainboard has a slot-1processor socket for an Intel
processor cartridge, and it also has a socket-370 for an Intel
PPGA (Plastic Pin Grid Array) Celeron processor. You can
install either one of these processors according to the power and
performance requirements that you need from your system. Note
that you cannot install two processors on this mainboard.
Slot-1 processors include the SEPP (Single Edge Processor
Package) Celeron, the Pentium-II, and the Pentium-III. Clock
rates run as high as 500 MHz. Socket-370 processors are the
PPGA Celeronwhich runs at clock rates up to 466 MHz. The
mainboard supports a system bus of 66 MHzor 100 MHz.
The mainboard uses the Xcel 2000 chipset which provides CPU
Plug & Play through firmware. The mainboard is highly integrated
and includes a built-in 64-bit AGP Graphics Accelerator, a built-
in PCI 3D Sound System, and a built-in 10BaseT/100BaseTX
Network Adapter. A V.90 Fax/Modem DAA module is also
shipped with the mainboard. In addition, it has a full set of ATX
I/O Ports including two PS/2 ports, two USB ports, a parallel port,
a serial port and a VGA port.
This mainboard has all the features you need to develop a powerful
multimedia workstation that is network ready, and has built -in
communications. The board is micro-ATX sizedand has power
connectors for ATX power supply units so it can be installed in a
micro-ATX case.

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.
3. 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:
qIdentify the mainboard components
qInstall the correct processor
qInstall one or more memory modules
qVerify that any jumpers or switches are at the correct setting
qInstall the mainboard in the system chassis
qInstall any extension brackets or cables tothe mainboard
headers
qInstall any other devices and make the appropriate connections
to the mainboard headers.
Note: 1. Before installing the mainboard, you must ensure that
jumper J9 is set to the Normal setting. See this chapter for
information on locating J9 and changing the jumper setting.
2. While installing the mainboard, please make sure the AC
power cord is unplugged before the full system is installed
completely. Otherwise, it may destroy stuffs unpredictably, due to
the power-on trigger event of power management.

Install the Processor
This mainboard has a Slot-1 which can be installed with any Slot-1
processor cartridge including the Pentium-III, the Pentium-II, and
the SEPP Celeron. It also has a Socket-370 which can be installed
with the new Celeron processor which is shipped in a PPGA
(Plastic Pin Grid Array) package. To ensure reliability, make
sure that your PPGA Celeron processor is fitted with a
heatsink/cooling fan assembly.
You can install a Slot-1 processor or a PPGA Celeron. 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. The following table lists the
processors that are currently supported by this mainboard. New
processors may be a released after this manual is printed.

Installing a Slot-1 Processor Cartridge
1. Locate Slot-1, FAN1, and J20 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 FAN1. Connect the cable
from the processor cartridge cooling fan to FAN1.
5. Locate the jumper J20. Use this jumper to short pins 2-3 if you
have installeda Slot-1 processor.
6. On this mainboard, you can configure the processor by
entering the correct settings in the BIOS setup utility.
Installing a Socket-370 Processor
The Celeron processor installs into the ZIF (Zero Insertion Force)
Socket-370 on the mainboard.
1. Locate the Socket-370, FAN1, and J20. Pull the locking lever
out from the socket and swing it to the upright position.

2. On the Celeron 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 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 processor in the
socket.
6. Locate the jumper J20. Use this jumper to short pins 1-2 if you
have installed a Socket-370 processor.
7. If the Celeron processor is installed with a cooling fan
assembly, connect the cable from the fan to the CPU fan power
connector FAN1.
Install Memory
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. You must install the first memory
module into DIMM1 so that it can share memory with the onboard
VGA system.
For this mainboard, you must use 168-pin, 3.3V memory modules
installed with SDRAM memory chips. If you are using a processor
DIMM1
DIMM2
DIMM3
Pin-1 Corner

that runs on a 100 MHz system bus, you must use memory that
operates on a 100 MHz memory bus (PC-100 memory). If you are
using a processor that runs on a 66 MHz system bus, you must use
memorythat operates on a 66 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 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 J9: 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 into the system chassis. This mainboard uses
the micro-ATX format with a twin-tier of I/O ports. Special micro-
ATX cases are available with a reduced number of expansion slots
and a smaller power supply unit. Ensure that your case has an I/O
template that can be used by this mainboard.
Install the mainboard into the unit case. Follow the instructions
provided by the case manufacturer using the screws and mounting
points provided in the chassis.
Connect the power cable from the power supply unit to the power
connector ATX Power on the mainboard. If the system chassis is
installed with a cooling fan, connect the cable from the cooling fan
to the chassis fan power connector on the mainboard FAN2.
