2. Board Installation
2.1 Unpacking
The mainboard package should contain the following:
wS1572 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 plugged in and turned off, touch an unpainted area of
the system chassis immediately before handling the mainboard or any com-
ponent. 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 any of the socket
IC's if it appears they are not 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 S1572 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. This function is built onto the Intel TX
chipset and cannot be field upgraded.
3.4 Speaker Connector Installation
S1572 provides a 4-Pin header to connect the speaker. The speaker is
connected to pins 24-27 of J8.
3.7 Hardware Reset Switch Connector Installation
The RESET switch on your cases' display panel provides users with the
HARDWARE RESET function 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 pins
22 and 23 on J8.
3.8 Flash EPROM-Jumper JP2
The S1572 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.
JP2 determines which type of EPROM is used. This jumper has been set
to match the on board BIOS chip. The factory default for the S1572 is on
pins 1-2. Depending on the type of EPROM used, some boards will have
JP2 on pins 2-3.
13
Refer to chapter 5 for Flash EPROM upgrade procedures.
3.9 Hardware CMOS & Password Reset
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. Jumper JP1 to pins 2 and 3.
d. Wait for 2 seconds then return the jumper to pins 1 and 2.
e. 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 S1572 uses a 64-bit data path from memory to CPU and can
accommodate up to 256MB 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, 8 and 16MBx32 SIMMs.
wSIMM bank 0, 1 and 2 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.
wIf you use 4Mx64 DIMMs you cannot use DRAM bank 2.
wWe do not recommend using DRAM bank 2 along with DIMMs.

3.11 CPU Installation
Several types of CPUs (75 thru 200MHz) can be used on S1572.
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 S1572's 512kb of on-board pipelined burst SRAM and cannot be
field upgraded. The TX chipset can cache a maximium of 64MB of
RAM.
3.13 Peripheral Device Installation
After all the jumpers on the mainboard have been set, then it can be mounted
into the case. 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.

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.

w Virus warning
This category flashes on screen. During and after the system boot up,
any attempt to write to the boot sector or the partition table of the hard
disk drive will halt the system and the following error message will
appear. In the meantime, you can run an anti-virus program to locate the
problem. Default value is Enabled.
"Attempting to write to boot sector, continue? Y/N"
Enabled Activate automatically when the system boots up causing a warning
message to appear when anything attemps to access the boot sector or hard
disk partition table.
Disabled No warning message to appear when anything attemps to access the boot
sector or hard disk partition table.

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.
The 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
encountered after flashing a BIOS will be solved by this simple
procedure.
37
To reprogram the System BIOS, you must first do the following:
1. Check jumper JP2.(Default pins 1-2)
The S1572 uses a 5V Flash EPROM so jumper JP2
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.SYSand 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.
38
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.

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 JP1 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 avoid
inconvenience.
