Board Installation
Chapter 2–Board Installation
2.1 Unpacking
The mainboard package should contain the following: wS1571 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 component. Doing so discharges the 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. Do not inspect board unless it is 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 S1571 matches the Baby-AT system board specifications. It is assumed that the chassis is for a standard Baby-AT mainboard form factor.

The S1571 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) are also supported in the DIMM slots. DIMMs must be of the unbuffered variety. 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.
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 SIMM modules.
wSIMM banks 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.

3.9 CPU Installation
Several types of CPUs can be used on the S1571. Please refer to section 3.2 for the correct CPU jumper settings for your board.
Remember:
w The 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
surface. You should be able to insert the CPU with minimal pressure.
Do not push down hard, but do use firm pressure.
w A cooling fan and/or heat sink assembly is required to protect
the CPU from being damaged.

Installation procedure:
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 of
the CPU 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.
3.10 Upgrading Cache Memory
The S1571 has 512KB of on-board pipeline-burst SRAM and cannot be upgraded in the field. The TX chipset can cache a maximium of 64MB of RAM.
3.11 Peripheral Device Installation
After all the jumpers on the mainboard have been set, it can then 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, you should check everything again, and prepare to power on the system.

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 640KB.
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.
Other Memory
This refers to memory located in the 640KB to 1024KB address space. This memory can be used for different applications. DOS uses this area to load device drivers in order to keep as much conventional memory free for application programs as possible. Often called “high memory.”

BIOS Configuration
What follows is a description of the menu options.
w Virus warning
This category flashes on-screen messages. 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 produce an error message. If a warning appears, then
you should run an anti-virus program to locate the problem. This feature
protects only the boot sector, not the entire drive. Note that some disk
diagnostic programs will trigger the virus warning message.
Enabled Activates automatically when the system boots up, causing a warning message to appear when anything attempts to access the boot sector or hard disk partition table.
Disabled No warning message will appear when anything attempts to access the boot sector or hard disk partition table.
w CPU Internal Cache and CPU External Cache
These two categories–when enabled–speed up memory access.
Enabled Enables the cache.
Disabled Disables the cache.
w Quick Power On Self Test
Select Enabled to reduce the amount of time required to run the power
on self test (POST). It should be noted that this test is quicker because it
skips some steps of the full POST.
w Boot Sequence
This category determines which drive the computer searches first for the
disk operating system (i.e. DOS).
A, C
C, A
System will first search for floppy disk drive, then hard disk drive.
System will first search for hard disk drive, then floppy disk drive.
w Swap Floppy Drive
If you have two floppy drives, you can choose to designate the physical A
drive as the logical B drive, and vice versa.
Enabled Floppy A and B will be swapped.
Disabled Floppy A and B will be defined normally.
S1571 D1181-001 http://www.tyan.com
28
BIOS Configuration w Boot Up Floppy Seek
During POST, the BIOS will determine if the floppy disk drive installed is
40 or 80 tracks. The 360KB type is 40 tracks, while the 720KB, 1.2MB,
and 1.44MB types are all 80 tracks.
Enabled BIOS searches for floppy disk drive to determine if it is 40 or 80
tracks. Note that the BIOS cannot distinguish between 720KB,
1.2MB, and 1.44MB drive types, as they are all 80 tracks.
Disabled BIOS will not search for the type of floppy disk drive by track
number. Note that there will not be any warning messages if the
drive installed is 360KB.
w Boot Up NumLock Status
Determines whether or not NumLock is active when the system boots.
On
Off
Number keys are active on keypad.
Arrow keys are active on keypad.
w Boot Up System Speed
Select High to boot at the default CPU speed; select Low to boot at
the speed of the AT bus. If you are using old software–or certain add-in
peripherals–you may need to use the slower CPU speed.
w Typematic Rate Setting, Typematic Rate (char/sec), and
Typematic Delay.
The Typematic Rate Setting option enables or disables the Typematic
Rate and Typematic Rate Delay options. TheTypematic Rate (6, 8, 10,
12, 15, 20, 24, or 30 characters per second) and Typematic Rate Delay
(250, 500, 750, or 1000 milliseconds) control the speed at which a
keystroke is repeated. Typematic Rate Delay controls the gap between
key compression and the appearance of the character on-screen. The
character is then printed repeatedly at the speed set by the Typematic
Rate.

BIOS Configuration w Security Option
This option allows you to select whether a password (if you have one) is
required each time the system boots, or only when you enter Setup.
System The system will not boot and access to Setup will be denied if the correct
password is not entered at the prompt.
Setup The system will boot, but access to Setup will be denied if the correct password
is not entered at the prompt.
w PS/2 Mouse
Enables or disables the PS/2 mouse resources.
w PCI/VGA Palette Snoop
Leave this field at Disabled.
w Shadow
This function allows BIOS to “shadow” firmware, that is, copy it from
ROM into the system RAM. Once there, it can be read through the 16-
bit or 32-bit DRAM bus by the CPU. Firmware that is not shadowed is
read through the 8-bit X-bus. Shadowing improves the performance of
the system BIOS and similar ROM firmware for expansion peripherals,
but reduces the amount of high memory (see page 26) available for
loading device drivers. Do not enable shadowing into all of the memory
at once; enable each section independently.

BIOS Configuration sAuto Configuration
This function selects the optimal values for your chipset parameters. If
Disabled, the chipset parameters will revert to setup information stored
in CMOS. When Auto Configuration is Enabled, many of the options
below will not be available.
sDRAM Timing
The value in this field is determined by the performance parameters of
the installed DRAM chips. Unless you install new memory that has a
different performance rating than the factory DRAMs, you should not
alter this field.
sDRAM Leadoff Timing
Select the combination of CPU clocks the DRAM on your board
requires before each read from or write to the memory. Beware:
changing the value from the setting determined by the board designer for
the installed DRAM may cause memory errors.
sDRAM Read Burst
Sets the timing for reads from EDO (Extended Data Output) or FP[M]
(Fast Page Mode) memory. The lower you set the timing numbers, the
faster the system will address the memory. Selecting timing numbers
lower than the installed DRAM is able to support can result in memory
errors.
sDRAM Write Burst Timing
Sets the timing for writes to memory. As above, the lower the timing
numbers, the faster the system will address the memory. Note that
selecting timing numbers lower than the installed DRAM is able to
support can result in memory errors.
sFast EDO Leadoff
Unless you have EDO DRAMS in a synchronous cache or cahceless
system, select Disabled. Enabling will cause a 1-HCLK pull-in for all
read leadoff latencies for EDO DRAMs (i.e., page hits, page misses, and
row misses). You should also select Disabled if any of the DRAM rows
contain FPM DRAMs.
sRefresh RAS# Assertion
Select the number of clock cycles in which RAS# is asserted for refresh
cycles.
S1571 D1181-001 http://www.tyan.com
31
BIOS Configuration sFast RAS# to CAS# Delay
Inserts a timing delay between the CAS and RAS strobe signals, used
when DRAM is refreshed, read from, or written to.
sDRAM Page Idle Timer
Select the time in HCLKs that the DRAM controller waits to close a
DRAM page after the CPU becomes idle.
sDRAM Enhanced Paging
When Enabled, the chipset keeps the page open until a page/row miss.
When Disabled, the chipset uses additional data to keep the DRAM page
open when the host may be only temporarily absent.
sFast MA to RAS# Delay
Do not change these values unless you change the specifications of the
installed DRAM or the installed CPU.
sSDRAM (CAS Lat/RAS-to-CAS)
You can select a combination of CAS latency and RAS-to-CAS delay in HCLKs of 2/2 or 3/3. The board designer should set these values based on the installed DRAM. As above, do not change the values in this field unless you change the specifications of the installed
DRAM or the installed CPU.
sSDRAM Speculative Read
The chipset can guess at a DRAM read address in order to reduce read latencies. A read request containing the data memory address is issued by the CPU, and received by the DRAM controller. If this function is Enabled, the controller issues the read command just before it has finished decoding the data address.
sSystem BIOS Cacheable
If Enabled, this function results in better video performance by
permitting caching of the video BIOS ROM at C0000h to C7FFFh.
Note that any program which tries to write to this area may cause a system error.
sVideo BIOS Cacheable
If Enabled, results in better system performance by permitting caching of the system BIOS ROM at F0000h-FFFFFh. Any program which tries to write to this memory area may cause a system error.
S1571 D1181-001 http://www.tyan.com
32
BIOS Configuration s8- and 16-Bit I/O Recovery Time
Because the PCI bus is so much faster than the ISA bus, the I/O
recovery mechanism adds bus clock cycles to the ISA bus between PCI-
originated I/O cycles. These two fields let you add recovery time (in bus
clock cycles) for both 8-bit and 16-bit I/O.
sMemory Hole at 15M-16M
You can reserve this area of the system memory for ISA adapter ROM.
As long as it is reserved, however, it cannot be cached. Any peripherals
that require this area of system memory will likely have a note in their
user information to that effect.
sPCI Passive Release
When Enabled, CPU to PCI bus accesses are allowed during passive
release. If Disabled, only another PCI master will have access to local
DRAM.
sPCI Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support compliance with
PCI specification version 2.1.
sPipeline Cache Timing
If your system contains a single bank of pipelined burst SRAM, select
Faster. If your system contains two banks of pipelined burst SRAM,
select Fastest.
sChipset NA# Asserted
If Disabled, NA# assertion depends upon cache size and type. If
Enabled, the NA# pin is never asserted. Further, the chipset will signal
the CPU for a new memory address before all the data transfers for the
current cycle are complete. This is called “pipelining.”
sMem. Drive Str. (MA/RAS)
Stands for Memory Address Drive Strength. Controls the strength of
the output buffers driving the MA and BA1 pins (first value) and
SCASx#, CKEx, MWEx#, and SRASx# pins (second value).
sDRAM Refresh Rate
In accord with your DRAM specifications, designate the period required
to refresh the DRAMs.

sIDE HDD Block Mode
The terms “multiple commands,” “multiple sector read/write,” and
“block transfer” are all alternate names for block mode. Unless your
IDE hard drive is old, it should support block mode. If Enabled, yields
automatic detection of the optimal number of block read/writes per
sector that the drive can support.
sIDE Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO
mode (0-4) for each of the four IDE devices supported by the onboard
IDE interface. Modes 0 through 4 provide successively increased
performance. In Auto mode, the system automatically determines the
best mode for each device.
Ultra DMA/33 can only be implemented if your IDE hard drive supports it and the operating environment includes a DMA driver. If your hard drive and your system software both support Ultra
DMA/33, select Auto to enable BIOS support.

Flash Writer Utility
Chapter 5–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 TYAN's BBS and from the Tyan website. 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.
README -A text file of instructions.
*S71AWXX.BIN
-XX represents a 2-digit version
number.
*This file name is subject to change and can have either a "bin" or a "rom" extension.
The Flash memory writer records (or ‘programs’) a new BIOS onto the flash memory chip. You cannot upgrade an Award BIOS to an AMI
BIOS or an AMI BIOS to an Award BIOS.
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.
To reprogram the System BIOS, you must first do the following:
1. Check jumper JP23 (default pins 1 and 2).
The S1571 uses a 5V Flash EPROM, so jumper JP23 should be left in the default position on pins 1 and 2. This jumper should never be moved, and on some boards has been hardwired.
S1571 D1181-001 http://www.tyan.com

Flash Writer Utility
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 before you can run
FMW. The easiest way to do this is as follows: 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 can access this feature by pressing <F5> while the
“Starting MS-DOS...” line is on the screen.
There are other ways to get FMW to run. The important thing is to ensure that no memory managers are running. If you are uncertain whether or not there is a memory manager running on your system, try running FMW. If it works, then there is no active memory manager. If you see a warning message about the CPU mode, check to see that you have followed the directions properly, and try again.
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. Either way, make sure that the new BIOS file is in the same directory as the FMW utility.
S1571 D1181-001 http://www.tyan.com

Flash Writer Utility
To start FMW, change to the “Flash” directory (if you are not already in it). Type “Awdflash” at the DOS command line and press the <Enter> key. The following screen will appear:

FLASH MEMORY WRITER V3.0

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 is highly recommended. If you can not sucessfully program the BIOS file for some reason, re-install your 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 such an inconvenience.
