User's Manual  
 
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 add-  
on 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 compo-  
nent. 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.  
13  
 
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 pass-  
word 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.  
14  
 
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 automati-  
cally 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.  
You can use SIMM bank 0 with DIMM bank 1.  
You can use SIMM bank 1 with DIMM bank 0.

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.  
wThe CPU is a sensitive electronic component and it can be easily  
damaged by static electricity. Do not touch the CPU pins with your  
fingers.  
wWhen installing the CPU into the socket, match the CPU pins to the  
socket pins.  
wBefore 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.  
wA 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.  
16  
 
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.  
wYou cannot disable the onboard cache and install a 512Kb "COAST"  
module to get 512Kb of cache. The onboard cache is always used.  
17  
 
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 periph-  
eral 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.

w Halt On  
The category determines whether the computer will stop if an error is  
detected during power up.  
No errors  
All errors  
Whenever the BIOS has detected a non-fatal error, the  
system will be stopped and you will be promted.  
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.  
w 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.  
25  
 
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.  
38  
 
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 suc-  
ceeded. If it displays a warning message about the CPU  
mode, you will have to try again.  
39  
 
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  
backup of the support floppy disk. Make sure the new BIOS file  
is in the same directory as the FMW utility.  
To run FMW, change to the “Flash” directory if you are not al-  
ready in it. Type “Awdflash” at the DOS command line and press  
the <Enter> key. The following screen will appear.

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 re-  
install 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.
