Install A CPU

This mainboard has a Socket-370 which supports 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-462/Socket -7 processor in the Socket-

370. A Socket-462/Socket -7 processor such as the AMD K7/

K6/K5, or the Pentium-MMX does not fit in the Socket 370.
The following list notes the processors that are currently supported

by this mainboard.

FCPGA Pentium III: 500~1130MHz, FSB: 100MHz, 133MHz
FCPGA Celeron: 533~800MHz, FSB: 66 MHz

Notice: This mainboard does not support PPGA Celeron CPUs.

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 FAN2. 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-370, identify the Pin-1 corner. The Pin-1 corner
is at the top of the locking lever when it locked.

DDR1

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 FAN2.

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.

Setting Jumper Switches

Jumpers are sets of pins which can be connected together with
jumper caps. The jum per 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.

BIOS Setup Utility

Introduction

The BIOS Setup Utility records settings and information about
your computer such as the date and time, the kind of hardware
installed, and various configuration settings. Your computer uses
this information to initialize all the components when booting up
and functions as the basis for coordination between system
components.

If the Setup Utility configuration is incorrect, it may cause the
system to malfunction. It can even stop your computer from
booting properly. If this happens, you can use the clear CMOS
jumper to clear the CMOS memory used to store the configuration
information.

You can run the setup utility and manually make changes to the
configuration. You might need to do this to configure some of the
hardware that you install on or connect to the mainboard, such as
the CPU, system memory, disk drives, etc.

Utility Folder Installation Notes

AMI Flash Memory Utility

This utility lets you erase the system BIOS stored on a Flash
Memory chip on the mainboard, and lets you copy an updated
BIOS to the chip. Take care how you use this program. If you erase
the current BIOS and fail to write a new BIOS, or write a new
BIOS that is incorrect, your system will malfunction.
For this mainboard, use AMI8XX.EXE to flash the BIOS (where
7XX is the version number). You can use any version, but we
suggest you use the latest version. To use the utility, you must be in
real -mode DOS (not the DOS box that is available in Windows
95/98/NT). If you are using WINDOWS 95/98, shut down your
computer and select the option Restart in DOS in the shutdown dialog
box. If you are running Windows NT, shut down your computer and
boot from a DOS diskette temporarily in order to run the flash
memory utility.

PC-cillin Software

The PC-cillin software program provides anti-virus protection for
your system. This program is available for Windows 2000/ME/
98SE and Windows NT. Be sure to check the readme.txt and install
the appropriate anti-virus software for your operating system.
We strongly recommend users to install this free anti -virus
software to protect your system against the various viruses that
may occur every day.
