1. Introduction
1.1 Overview
The S1472 is a quality, high performance mainboard designed for Intel
Pentium microprocessors. This mainboard utilizes the Intel 430VX chipset
and can support CPU speeds of 75MHz through 200MHz. S1472 will
also support the CyrixM1/6x86 CPU's and the Intel multimedia Pentium
P55C which utilizes MMX commands.
The S1472'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, on-board high speed I/O, and
support for pipeline-burst SRAM.
Flexibility and expandibility have been designed into the S1472. With I/O
and drive controller support built on-board, the five PCI and three 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:
wS1472 Mainboard
wOne IDE 40 pin cables
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 imedietly 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 S1472 matches the ATX system board spec. It is assumed that the
chassis is for a standard ATX mainboard form factor.

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 Speaker Connector Installation
S1472 provides a 4-Pin header (J48) to connect the speaker. The polarity
can go either way.
3.5 Turbo Switch
The front panel on your case may have a turbo switch to control system
speed when slower program execution is required for software developed
in the old XT days.
You can connect the chassis turbo switch to J50 on the mainboard. The
430VX chipset doesn't support a hardware turbo function so this switch will
only turn on or off the turbo LED.
3.6 Turbo LED Connector Installation
The TURBO LED on the front case panel can indicate the current speed
status of the system. The TURBO LED connector should be installed to
J51 in the correct direction.
