Introduction
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.
Remember to take a look at TYAN Computer’s web site located at http://www.tyan.com. There you can find information on all of TYAN’s products along with FAQs, distributors list, drivers and CMOS setting explanations. If you have a tech support question please contact us at www.tyan.com.
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.

Technical Support
If a problem arises with your system, you should first turn to your dealer for help. Your system has most likely been configured by them, and they should have the best idea of what hardware and software your system contains. Hence, they should be able to be of the most assistance. Further, if you purchased your system from a dealer near to you, you can actually bring your system in to them to have it serviced, instead of attempting to yourself (which can have expensive conse­quences). If your dealer is unable to assist you: Try our web page – http:// www.tyan.com, or user newsgroup – alt.comp.periphs.mainboard.tyan.
Returning Merchandise for Service
During the warranty period, contact your distributor or system vendor FIRST for any product problems. This warranty only covers normal customer use and does not cover damages incurred during shipping or failure due to the alteration, misuse, abuse, or improper maintenance of products.

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.

Windows 95 Users:
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).

battery
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.
RFU
Buffered
Unbuffered
168-pin DIMM
Make sure you do not attempt to install a 168-pin DIMM (shown above) in a socket designed for a 72-pin SIMM (shown below), or vice­versa.
72-pin SIMM
Some details of memory installation:
s SIMM modules must be installed in pairs. s Each pair of SIMMs must be of the same size and type. s The mainboard supports 4MB, 8MB, 16MB, 32MB, and 64MB
SIMMs.
s SIMM banks 0, 1, and 2 can use either double- or single-sided
SIMMs.
s Two SIMMs or one unbuffered DIMM must be installed for the
system to POST.
s The mainboard supports 16MB, 32MB, and 64MB DIMM mod-
ules.
s SIMM bank 0 and DIMM bank 0 cannot be used at the same time. s SIMM bank 1 and DIMM bank 1 cannot be used at the same time. s You can use SIMM bank 0 with DIMM bank 1. s You can use SIMM bank 1 with DIMM bank 0 (see motherboard
map on page 14).
s If you use 4MBx64 DIMMs you cannot use SIMM bank 2. s We do not recommend using SIMM bank 2 along with DIMMs.

CPU Installation
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:
s The CPU is a sensitive electronic component and it can easily be
!
damaged by static electricity. Do not touch the CPU pins with your fingers.
s When 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.
s Before 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.
