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 JP1 is set
to Normal, the default setting. See this chapter for information
on locating JP1 and the setting options.
2. Never connect power to the system during installation. Doing
so may damage the mainboard.

2: Mainboard Installation
Install A CPU
This mainboard has a Socket 370 which supports PPGA/FCPGA
Celeron and FCPGA Pentium III processors.
To 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.
A processor installs into the ZIF (Zero Insertion Force) Socket-370
on the mainboard.
1. Locate the Socket-370 and CPUFAN1. 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.

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.
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.
For this mainboard, you must use 168-pin, 3.3V unbuffered
SDRAM memory modules. If the installed CPU uses a 66/100
MHz system bus, you must use PC100/PC133 memory. If the
installed CPU uses a 133 MHz system bus, you must use PC133
memory. You can install any size memory module from 8 MB to
256 MB, so the maximum memory size is 2 x 256 MB = 512 MB.
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.
