1. Introduction
1.1 Overview
The S1572 is a quality, high performance mainboard designed for Intel
Pentium microprocessors. This mainboard utilizes the Intel 430TX chipset
and can support CPU speeds of 75MHz through 200MHz. The S1572
will also support the CyrixM1/6x86 CPU's and the Intel multimedia
Pentium with MMX processor, both the P55C and P54CTB Overdrive
versions.
The S1572'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,
DMA IDE and UltraDMA/33, on-board floppy controller, on-board high
speed I/O, and support for pipeline-burst SRAM.
Flexibility and expandibility have been designed into the S1572. 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.

Notice
This board uses the Intel 430TX chipset. According to Intel , the USB
function in this chipset is not guaranteed. Compatibility tests cannot be
conducted for USB at this time due to no availability of Operating
System support for these devices. Please log on to the Tyan web page for
the latest infomation.

2. Board Installation
2.1 Unpacking
The mainboard package should contain the following:
wS1572Mainboard
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.

14S1572-001-01 http://www.tyan.com
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.

15S1572-001-01 http://www.tyan.com
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.
wThe following table shows some of the available memory configurations.

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

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.

18S1572-001-01 http://www.tyan.com
4. BIOS Configuration
Award's BIOS has a built in setup program that allows the user to modify
the basic system configuration. This type of information is stored in the
battery-backed CMOS NVRAM. Entering incorrect information or for-
getting your password can lock you out of your system.(refer to 3.9
for resetting of CMOS)
