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.
13S1472-001-01 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 J46
The S1472 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.
J46 determines which type of EPROM is used. This jumper has been set
to match the on board BIOS chip. The factory default for the S1472 is on
pins 1-2. Depending on the type of EPROM used, some boards will have
J46 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 J38.(Put jumper on J38)
d. Wait for 5 seconds then remove the jumper from J38.
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.
14S1472-001-01 http://www.tyan.com
3.10 DRAM Installation
The S1472 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 S1472.
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.
16S1472-001-01 http://www.tyan.com
3.12 Upgrading Cache Memory
The S1472 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 J8 and put jumper J7 on 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.
17S1472-001-01 http://www.tyan.com
3.13 Peripheral Device Installation

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.
25S1472-001-01 http://www.tyan.com
Expanded Memory
Expanded Memory (EMS) defines a 64K 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
You can upgrade the BIOS of your mainboard by using a "Flash
Memory Writer"(FMW) utility. This utility can be downloaded from the
factory's BBS(Consult your system vendor for the phone #). 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
*S72AWXX.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.
38S1472-001-01 http://www.tyan.com
To reprogram the System BIOS, you must first do the following:
1. Check jumper J46.(Default pins 1-2)
The S1472 uses a 5V Flash EPROM so jumper J46
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.
39S1472-001-01 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 VX/HX-2A59CT51 Date:4/13/95
File Name to Program:
Error Message:
Type in the whole file name, e.g. A61AW10.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.
