Introduction
Overview
The S1573S 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 233MHz. The
S1573S will also support the Cyrix M1/6x86 and M2/6x86MX CPU’s,
the AMD K5/K6 CPU’s, and the Intel multimedia Pentium P55C and
P54CTB (MMX Overdrive) CPU’s.
The S1573S’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 an ATX formfactor. Some of the features included are onboard dual channel PCI
PIO, BUS Master IDE and UltraDMA/33, onboard floppy controller,
onboard high speed I/O, and support for pipeline-burst SRAM.
4
Flexibility and expandability have been designed into the S1573S. With
I/O and drive controller support built onboard, the five PCI and three
ISA slots (one ISA and one PCI as a shared slot) are free for numerous add-on expansion cards.

Icons
In order to help you navigate this manual and set up your system, we
have added several icons to our format.
This icon alerts you to particularly important details regarding the setup or maintenance of your system. This icon often
!
appears next to information that may keep you from damaging your board or system. While we will often point out the most vital
paragraphs in a chapter, you should always read every word in the text.
Failing to do so can lead to exasperation and expense.
INTRO
Wherever possible, we have included step-by-step instructions for setting up your system, which are indicated by this
icon. However, it is in your best interest to read an entire
section (and perhaps the entire manual) before you begin to alter the
settings on your motherboard.
While we have alerted you to potential dangers in several
places in this manual with this icon, these warnings should
not be regarded as the whole of your safety regimen.
Never forget that computers are electrical devices, and are capable of
delivering a burn or shock. Prevent damage to yourself and to your
board: always ensure that your system is turned off and unplugged
whenever you are working with it, and that you are equipped with a
static safety device.

Board Installation
Unpacking
The mainboard package should contain the following:
•S1573S Mainboard
•One IDE 40 pin cable
•One 34 pin floppy cable
•User’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 component. Doing so discharges any static charge your body
may have acquired.
After opening the mainboard carton, extract the system board-holding it
by its edges-and place it on a grounded anti-static surface, component
side up. Inspect the board for damage. Press down on any of the
10
socket ICs if it appears that they are not properly seated (the board
should still be 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!
Installation
You are now ready to install your mainboard. The mounting hole pattern
of the S1573S matches the ATX system board specifications. Your
chassis should be that of a standard ATX mainboard form factor.

You may encounter problems with some of the devices in the Intel
82371AB chipset. Neither the PCI Bridge nor the PCI Universal Serial
BUS device IDs for this chipset (also called PIIX4) are recognized by
Windows 95. This is a software problem, not a hardware problem, and
can be easily remedied by either upgrading to Windows 98 or downloading the 82371AB patch found at http://www.tyan.com or at ftp://
download.intel.com/design/pcisets/busmastr/setupex.exe. (Note: USB
requires Windows 95 OSR 2.1 or above; please contact Microsoft for
USB update.)
Disclaimer:
!
This motherboard incorporates support for 75MHz and 83MHz BUS
speeds. However, these speeds will push PCI bandwidth beyond the Intelrecommended specification for PCI 2.1 compliance. Therefore, TYAN
Computer Corporation takes no responsibility for any problems, be they
hardware or software, related to the use of BUS speeds beyond 66MHz.
We also cannot guarantee any PCI cards’ compatibility beyond the specified speed of 33MHz. Technical support and RMA/Warranty claims relating to the use of BUS speeds beyond the 66MHz/33MHz limit recommended by Intel will not be honored by TYAN. Use at your own risk.
CMOS RTC
The 430TX chipset includes an internal
battery and Real Time Clock circuit. The
RTC provides the date and time for the
system. If the battery is low, it will
prevent your system from POSTing, and
you will not get a display. Normally the
life span of an RTC internal battery is 10
years, but if yours is running low, you will
need to replace it with a new 3V lithium
battery (Duracell DL2032).

Soft Power Connector
The Soft Power Connector is located on pins 1 and 2 of jumper block
J8. Pressing the Soft Power Button will turn the system on (and off). If
you hold this button down for more than four seconds, the chipset will
shut down, but the power will remain on. Pressing the button again will
reboot the system.
Sleep Button Connector
The sleep button connector is located on pin 3 and pin 4 of jumper block
J8. Pressing this button once will put the system in Sleep (or Suspend)
mode. Pressing this button again will wake the system up.
Speaker Connector Installation
The S1573S provides a 4-pin header to connect the speaker. The
speaker is connected to pins 24-27 on jumper block J8.
Power LED
The power LED is lit when the system is on, is not lit when the system
is off, and blinks when the system is in Sleep (or Suspend) mode.
External SMI
The external SMI is located at jumper J90. The pin assignment is pin1:
external SMI; pin 2: GND.
Hardware Reset Switch Connector
ONBOARD
Installation
The Reset switch on your case’s display panel provides you with the
Hardware Reset function, which is the same as power on/off. The
19
Chapter 3
system will do a cold start after the Reset button is pushed. The Reset
switch is a 2-pin connector and should be installed on pins 22 and 23 on
jumper block J8.
Flash EEPROM
The S1573S uses flash memory to store BIOS programs. It can be
updated as new versions of the BIOS become available. The flash
utility will guide you through the update process step by step (see
Chapter 5).
JP2 determines which type of EPROM is used. This jumper has been
set to match the onboard BIOS chip. The factory default for the
S1573S is on pins 1-2. Depending on the type of EPROM used, some
boards will have JP2 on pins 2-3.
Hardware CMOS & Password Reset
If you have been locked out of your system because you forgot your
password or set the CMOS incorrectly, follow the instructions below.
1. Power off the system
2. Set jumper JP1 to pins 2 and 3 (see previous page for
location of JP1).
3. Wait for 2 seconds, then return jumper JP1 to pins 1 and 2.
4. Power on the system again.
By following this procedure, you will erase your password and reset the
CMOS to the BIOS defaults.
DRAM Installation
The S1573S 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. SDRAMs
(Synchronous DRAMs) are also supported in the DIMM slots. DIMMs
must be of the unbuffered variety. The position of the notch in the
!
DRAM Key Position will tell you whether or not a DIMM is unbuf-
20
fered (see figure below). All installed memory will be automatically
detected, so there is no need to set jumpers. The TX chipset can cache
up to 64MB of RAM.

sTwo SIMMs or one unbuffered DIMM must be installed for the
system to POST.
sThe mainboard supports 16MB, 32MB, and 64MB DIMM mod-
ules.
sSIMM bank 0 and DIMM bank 0 cannot be used at the same time.
sSIMM bank 1 and DIMM bank 1 cannot be used at the same time.
sYou can use SIMM bank 0 with DIMM bank 1.
sYou can use SIMM bank 1 with DIMM bank 0 (see motherboard
map on page 14).
sIf you use 4MBx64 DIMMs you cannot use SIMM bank 2.
sWe do not recommend using SIMM bank 2 along with DIMMs.

Several types of CPUs (75 through 233MHz) can be used on the
S1573S. Please refer to page 13 for the correct CPU jumper settings
for your board.
Remember:
sThe CPU is a sensitive electronic component and it can easily be
!
damaged by static electricity. Do not touch the CPU pins with your
fingers.
sWhen installing the CPU into the socket, match the CPU pins to
the socket pins. Note that one corner of the socket’s top is different from the other three corners. Likewise, one corner of the
CPU’s bottom is different from the other three corners. Line the
unique socket corner up with the unique CPU corner.
sBefore the CPU is installed, the mainboard must be placed on a flat
surface. You should be able to insert the CPU with minimal, but
firm, pressure. Do not press down hard on the CPU.
