1. Introduction

1.1 Overview

The S1470 is a quality, high performance mainboard designed forl Intel
Pentium microprocessors. This mainboard utilizes the Intel 430VX chipset
and can support CPU speeds of 75MHz through 200MHz. S1470 will
also support the CyrixM1/6x86 CPU's and the Intel multimedia Pentium
P55C which utilizes MMX commands.

The S1470'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 "Baby-AT" form­factor. 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 S1470. With I/O
and drive controller support built on-board, the five 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:

wS1470 Mainboard
wOne IDE 40 pin cables
wTwo serial cables

wwOne parallel 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 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 S1470 matches the "Baby AT" system board spec. It is assumed that
the chassis is for a standard IBM XT/AT 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

S1470 provides a 4-Pin header (J41) 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 J42 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
J50 in the correct direction.

12S1470-001-01 http://www.tyan.com

3.7 Hardware Reset Switch Connector Installation

The RESET switch on your cases' display panel provides users with the
HARDWARE RESET functinon which is the same as power on/off. The
system will do a cold start after the RESET switch is pushed by the user.
The RESET switch is a 2 pin connector and should be installed on jumper
J49.

3.8 Flash EPROM-Jumper J54

The S1470 uses flash memory to store BIOS programs. It can be updated
as new versions of the BIOS becomes available. The flash utility will guide
you through the process step by step.

J54 determines which type of EPROM is used. This jumpers has been set
to match the on board BIOS chip. The factory default for the S1470 is on
pins 1-2. Depending on the type of EPROM used, some boards will have
J54 on pins 2-3.

Refer to chapter 5 for Flash EPROM upgrade procedures.

3.9 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 J43. (Put jumper on it)

d. Wait for 5 seconds then remove the jumper from J43.

e.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 default.

13S1470-001-01 http://www.tyan.com

3.10 DRAM Installation

The S1470 uses a 64-bit data path from memory to CPU and can
accommodate up to 128 MB of RAM. The mainboard supports Fast
Page Mode, and EDO (Extended Data Out) 72 pin SIMMs.
SDRAM(Synchronous) are also supported in the DIMM slots. DIMM's
must be of the unbuffered variety. All installed memory will be automati­cally detected so there is no need to set jumpers.

wSIMM modules must be installed in pairs.
wEach pair of SIMMs must be of the same size and type.
wThe mainboard supports 1, 2, 4 and 8MBx32 SIMMs.
wSIMM bank 0 and 1 can use either double or single sided SIMMs.
wTwo SIMMs or One unbuffered DIMM must be installed for the system

to POST.

wSDRAM DIMMs can be installed one at a time.
wThe mainboard supports 1, 2 and 4Mx 64 DIMM modules.
wSIMM bank 0 and DIMM bank 0 cannot be used at the same time.

SIMM bank 1 and DIMM bank 1 cannot be used at the same time.

3.11 CPU Installation

Several types of CPUs (75 thru 200MHz) can be used on S1470.
Please refer to section 3.2 for the correct CPU jumper settings for your
board.

w The CPU is a sensitive electronic component and it can be easily
damaged by static electricity. Do not touch the CPU pins with your
fingers.

w When installing the CPU into the socket, match the CPU pins to the
socket pins.

w Before the CPU is installed, the mainboard must be placed on a flat
plane. You should be able to insert the CPU with minimal pressure.
Do not push down hard, use firm pressure.

w A cooling fan and heat sink assembly is required to protect the
CPU from being damaged.

1. Make sure the ZIF socket lever is up. To raise the lever, pull it out
to the side a little and raise it as far as it will go. The top plate will
slide back.

2. Align the CPU and socket Pin 1 corners. The pins on the bottom
should align with the rows of holes in the socket.

3. Insert the CPU in the socket. It should insert easily. If it does
not, adjust the position of the lever a little.

4. Press the lever down. The top plate will slide forward. You will
feel some resistance as the pressure starts to secure the CPU in
the socket. This is normal and will not damage the CPU.
The lever should snap into place at the side of the socket.

15S1470-001-01 http://www.tyan.com

3.12 Upgrading Cache Memory

The S1470 has 256Kb of on-board pipelined burst SRAM and

can be upgraded to 512Kb by adding a Tyan approved 256Kb
cache module. Please refer to your vendor for the approved
upgrade modules.

wRefer to page 9 for the cache jumper settings.

wWhen upgrading to 512Kb cache, you must use a 256Kb "COAST"

module and open jumper J20 and set J21 to pins 1-2.

wOnly use Tyan approved 256Kb "COAST" modules when upgrading.

wThe "COAST Module" will only fit in the "Coast Socket" one way and

should install easily.

wwYou cannot disable the onboard cache and install a 512Kb "COAST"
module to get 512Kb of cache. The onboard cache is always used.

16S1470-001-01 http://www.tyan.com

3.13 Peripheral Device Installation

After all the jumpers on the mainboard have been set, then it can be mounted
into the case. Then proceed to install the display card and any other periph­eral devices.

If a PCI-Bus interface card is to be installed in the system, any one of the
five PCI-Bus slots can support either a Master or a Slave device.

After installing the peripheral controllers, the user should check everything
again, and prepare to power-on the system.

17S1470-001-01 http://www.tyan.com

ww Video

This category detects the type of graphics adapter used for the primary
display system. It must match your video display card and monitor. Al­though secondary monitors are supported, you do not have to select that
type in setup.

EGA/VGA Enhanced Graphics Adapter/Video Graphics Array.

For VGA,SVGA, or PGA monitor adapters.
CGA 40 Color Graphics Adapter, power up in 40 column mode.
CGA 80 Color Graphics Adapter, power up in 80 column mode.
Mono Monochrome adapter, includes hi-res monochrome.

ww Halt On

The category determines whether the computer will stop if an error is
detected during power up.

No errors Whenever the BIOS has detected a non-fatal error, the

system will be stopped and you will be promted.
All errors The system boot will not be stopped for any errors that

are detected.
All, but Keyboard The system boot will not stop for a keyboard error;it

will stop for all other errors.
All, but Diskette The system boot will not stop for disk errors; it will

stop for all other errors.
All, but Disk/Key The system boot will not stop for a keyboard or disk

error; it will stop for all other errors.

ww Memory

The category is for display-only and it is determined by POST Power On
Self Test of the BIOS.

Base Memory

The POST of the BIOS will determine the amount of

base (or conventional) memory installed in the system.

The value of the base memory is typically 640K.

Extended Memory

The BIOS determines how much extended memory is

present during the POST. This is the amount of

memory located above 1MB in the CPU's memory

address map.

26S1470-001-01 http://www.tyan.com

Expanded Memory

Expanded Memory (EMS) defines a 64Kb page frame in

the area between 640K and 1Mb containing four 16K pages

that are windows into the EMS memory. Programs issue

requests to the EMS manager to switch the page to any

part of EMS memory. Extended memory can be converted

to emulate EMS by using a memory manager such as

EMM386 that ships with Windows and DOS.

Other Memory

This refers to memory located in the 640K to 1024K ad

dress space. This memory can be used for different

applications. DOS uses this area to load device drivers to

keep as much conventional memory free for application

programs as possible.

5.0 Flash Writer Utility

Warning: Do not flash the BIOS unless instructed by your dealer.

You can upgrade the BIOS of your mainboard by using a "Flash
Memory Writer"(FMW) utility. This utility can be downloaded from
Tyan's BBS(Consult your system vendor for the phone #) or web site.
The system BIOS is stored on a 'flash' EPROM ROM chip on the
mainboard which can be erased and reprogrammed by the FMW.
The following three files make up the FMW.

AWDFLASH.EXE -The Flash Memory Writer utility for

Award to Award upgrade.

AMIFLASH.COM -The Flash Memory Writer utility for

AMI to AMI upgrade.
README -A text file of instructions
*S70AWXX.BIN -XX-A 2-digit version number.

Flash memory writer records (or ‘programs’) a new BIOS
onto the flash memory chip. You cannot upgrade an Award
BIOS to a AMI BIOS or a AMI BIOS to an Award BIOS.

*This file name is subject to change and can have either a "bin" or a
"rom" extention.

Note

You should ALWAYS clear your CMOS after flashing a BIOS.
This will clear out any stray settings from your old BIOS which may
have been carried over from the flashing process. Most problems
encounterd after flashing a BIOS will be solved by this simple
procedure.

39S1470-001-01 http://www.tyan.com

To reprogram the System BIOS, you must first do the following:

1. Check jumper J54.(Default pins 1-2)

The S1470 uses a 5V Flash EPROM so jumper J54
should be left in the default postion on pins 1 and 2. This
jumper should never be moved.

2. Make sure the CPU is running in ‘real mode’.

FMW will not run if the CPU is operating in a protected or
virtual mode. This means that you can not run it with Windows
running or with any memory manager software. You must
disable any memory manager first. The easiest way to do this
is to:

a. Boot your system from a bootable floppy disk with no
CONFIG.SYS or AUTOEXEC.BAT files, and then run Flash
Memory Writer from a backup copy of your support disk. You
can make your back-up floppy bootable when you format it, and
use one disk for both purposes.

b. If you are using MS-DOS 6.x, you can use the feature that
allows you to bypass the CONFIG.SYS and AUTOEXEC.BAT

file. You do this while pressing <F5> while the “Starting MS-

DOS...” line is on the screen.

There are other ways to accomplish the same result. The main
point is to make sure no memory managers are running. If you
are not sure, try running FMW. If it runs, then you have suc­ceeded. If it displays a warning message about the CPU
mode, you will have to try again.

40S1470-001-01 http://www.tyan.com

Once you have satisfied the two requirements mentioned above,

you can run FMW. You can copy the contents of the “Flash”
directory to your hard drive, or you can run the utility from a
backupof the support floppy disk. Make sure the new BIOS file
is in thesame directory as the FMW utility.

To run FMW, change to the “Flash” directory if you are not al­ready in it. Type “Awdflash” at the DOS command line and press
the <Enter> key. The following screen will appear.

5.1 The Flash Memory Writer Utility Screen (Award)

FLASH MEMORY WRITER V3.0

Copyright (C) 1993, AWARD Software Inc.,

For FX/HX-2A59CT51 Date:4/13/95

File Name to Program:

Error Message:

Type in the whole file name, e.g. A70AW10.BIN and confirm

that you want to program the BIOS. The utility will then ‘Blank’,
‘Erase’, and then ‘Program’ the flash memory on the mainboard with the
new BIOS file. You should choose “yes” to save the original system
BIOS to a floppy diskette before you program the new BIOS. This
leaves you with a backup of your original BIOS in case you need to re­install it. This option is highly recommended. If you can not sucessfully
program the BIOS file for whatever reason, re-install you original BIOS
from the backup file. Always reset the CMOS with jumper J43 after
flashing to a new BIOS.

Warning: If you do not successfully install a complete BIOS file

in the flash memory on the Mainboard, your system may not be able to
boot. If this happens, it will require service by your system vendor.
Follow the requirements and instructions in this section precisely to aviod
inconvenience.
