1. Introduction

1.1 Overview

The S1672 is a quality, high performance mainboard designed for Intel
Pentium Pro microprocessors. This mainboard utilizes the Intel 440FX
chipset and can support CPU speeds of 150MHz through 200MHz.

The S1672's PCI Local Bus provides high performance capabilities that
are ideal for a wide range of demanding applications such as: CAD,
CAM, CAE, networking, multi-user environments, database management,
desktop publishing, image processing and 3D animation.

This integrated system board achieves high reliability with numerous
features and yet is small enough to be supported in a "ATX" form-factor.
Some of the features included are: on-board dual channel PCI PIO and
DMA IDE, on-board floppy controller, and on-board high speed I/O.

Flexibility and expandibility have been designed into the S1672. With I/O
and drive controller support built on-board, the four PCI and four ISA
(One ISA and one PCI as a shared slot) slots are free for numerous add­on expansion cards.

2. Board Installation

2.1 Unpacking

The mainboard package should contain the following:

wS1672 Mainboard
wOne IDE 40 pin cable
wOne 34 pin floppy cable
wUser's Manual

The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original
packaging until it is ready to be installed.

With the power supply pluged in and turned off touch an unpainted area of
the system chassis immediately before handling the mainboard or any com­ponent. Doing so discharges the static charge your body may have built.

After opening the mainboard carton, extract the system board holding it by
its edges ,and place it only on a grounded anti-static surface, component
side up. Inspect the board for damage. Press down on all of the socket IC's
to make sure that they are properly seated. Do this only with the board
placed on an anti-static mat. Do not touch the bottom of the board.

DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN
DAMAGED!

2.2 Installation

You are now ready to install your mainboard. The mounting hole pattern of
the S1672 matches the ATX system board spec. It is assumed that the
chassis is for a standard ATX mainboard form factor.

CMOS registers, just power off the system and close
jumper J42for five seconds. Then open jumper J42 and
power on the system. This will set the CMOS and password
back to the system default.

3.3 CMOS RTC

CMOS RTC includes an internal battery and Real Time Clock circuit. It
provides the date and the time for the system. Normally the life span of a
RTC internal battery is 10 years. When replacing, you should use the same
model.

3.4 Flash EEPROM-Jumper J43

The S1672 uses flash memory to store BIOS data. It can be updated as
new versions of the BIOS becomes available. The flash utility will guide
you through the process step by step. If your system is functioning properly,
you may want to forego updating your BIOS in the event the new one
causes problems with your existing hardware and software.

J43 determines which type of EPROM is used. This jumper has been set
to match the on board BIOS chip. The factory default for the S1672 is on
pins 1-2.

Refer to chapter 6 for Flash EEPROM upgrade procedures.

3.5 Hardware CMOS & Password Reset

(The following steps are valid provided the board has a DS12887A RTC)

If you have been locked out of your system because you forgot your pass­word or set the CMOS incorrectly, follow the instructions below.

a. Power off the system

b. Short jumper J42.

c. Wait for 5 seconds then remove the jumper from J42.

d.Then power on the system again.

By doing the above procedures, your password will be erased and the CMOS
will be reset to the BIOS defaults.
