1. Introduction
1.1 Overview
This integrated system board achieves the highest reliability and yet is
small enough for all of its features to be supported in a "Baby-AT" form-
factor. Some of the features included are: on-board dual channel PCI
IDE, on-board floppy controller, on-board high speed I/O, and support for
pipeline-burst SRAM.
Flexibility and expandibility have been designed into the S1563. With I/O
and drive controller support built on-board, the four PCI and five ISA
(One ISA and one PCI as a shared slot) slots are free for any add-on
expansion cards. With eight SIMM sockets, the S1563 can provide a very
flexible memory configuration of 8MB to 512MB of RAM. With the
S1563D's support for dual Pentium processors, you can start a system
with just one CPU, and later add another, when more processing power is
required.
Notice
This board uses the Intel 430HX 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 such devices
and drives. Please log on to the Tyan web page for the latest infomation.

2. Board Installation
2.1 Unpacking
With the power supply pluged in and turned off touch an unpainted area of
the system chassis imedietly before handling the mainboard or any compo-
nent. 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 all of the socket IC's
to make sure that they are properly seated. Do this only with the board
placed on an anti-static mat. Do not touch the bottom of the board.
2.2 Installation
You are now ready to install your mainboard. The mounting hole pattern of
the S1563 matches the "Baby AT" system board spec. It is assumed that
the chassis is for a standard IBM XT/AT form factor.

CPU Voltage Regulator Settings:
Pentium MMX requires two voltage sources, J60, J61, & J62 are settings for
one source. J63, J64 and J65 are settings for the second voltage source. The
default setting is for P54C/Cyrix CPU's.
S1563-001-01 www.tyan.com 12
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. When replacing, you should use the same
model.
S1563 provides a 4-Pin header (J23) to connect the speaker. The polarity
can go either way.
The front panel on your case may have a turbo switch to control system
speed when slower program execution is required for software developed
in the old XT days.
The Intel 430HX chipset doesn't support a de-turbo mode, but the S1563
has a connector (J26) for the cable that may come with the case.
The TURBO LED on the front case panel can indicate the current speed
status of the system. The TURBO LED connector should be installed to
J25 in the correct direction.
S1563-001-01 www.tyan.com 13
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 jumper
J27.
The S1563 uses flash memory to store BIOS data. It can be updated as
new versions of the BIOS becomes available. The flash utility will guide
you through the process step by step. If your system is functioning properly,
you may want to forego updating your BIOS in the event the new one
causes problems with your existing hardware and software.
J48 determines which type of EPROM is used. This jumper have been
set to match the on board BIOS chip. The factory default for the S1563 is
on pins 1-2.
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
By doing the above procedures, your password will be erased and the CMOS
will be reset to the BIOS defaults.
S1563-001-01 www.tyan.com 14
3.10 DRAM Installation
The S1563 uses a 64-bit data path from memory to CPU and can
accommodate up to 512 MB of RAM. The mainboard supports
standard, EDO (Extended Data Out) and ECC(Error Correcting Code)
72 pin SIMMS . All installed memory will be automatically detected so
there is no need to set jumpers.

3.11 CPU Installation
Many types of Pentiums (75 thru 200 MHz) and Cyrix CPUs can be
used on the S1563. Please refer to the previous pages for the correct CPU
jumper settings for your board.
w When installing the CPU into the socket, match the CPU pins to the
socket pins.
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.
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.
S1563-001-01 www.tyan.com 18
3.12 Cache Memory
wThe BIOS will auto detect the cache size so a you don't need to change
any jumpers.
S1563-001-01 www.tyan.com 19
3.13 Understanding The Different Clock Speeds
The following chart shows the different CPU, mainboard and PCI fre-
quencies. As you may have noticed, all the Intel Pentium CPUs use an
internal clock multiplier(x3, x2.5, x2 or x1.5 Motherboard speed). All
Cyrix 6x86 can only use a x2 clock mulitipplier.
In the table above, the 50, 60 and 66.67 MHz figures are oscillator speeds
that establish the external clock speed. The PCI Bus clock speed is fixed at
one half of the mainboard clock speed. The 150MHz Pentium when set for
2.5x mode will achieve a 30MHz PCI bus speed but if it is set for 3x mode
you will get a slower 25MHz PCI bus speed.
Since all of the Cyrix 6x86 CPU's use a x2 mulitplier, the 100MHz P120+
must run on a 50MHz host bus. The PCI speed will then be at 25MHz.
S1563-001-01 www.tyan.com 20
3.14 Peripheral Device Installation
After all the jumpers on the mainboard have been set, then it can be mounted
into the case. Then proceed to install the display card and any other periph-
eral devices.
After installing the peripheral controllers, the user should check everything
again, and prepare to power-on the system.

To connect the leads from either voltage power supply, you should first
make sure the power supply is unplugged. Most power supplies have two
leads. Each lead has six wires, two of which are black.
Orient the connectors so the black wires are in the middle of the
5V power supply.
S1563-001-01 www.tyan.com 22
Align the plastic guide pins on the lead cables to their receptacles on the
mainboard. You may need to hold the lead at an angle to line it up.Once
you have the guide pins aligned, press the lead connector so that the
plastic clips on the lead snap into place and secure the lead to the connec-
tor.

display system. It must match your video display card and monitor. Al-
though secondary monitors are supported, you do not have to select that
type in setup.
All errors Whenever the BIOS has detected a non-fatal error, the
system will be stopped and you will be promted.

All, but Diskette The system boot will not stop for disk errors; it will
stop for all other errors.
All, but Disk/Key The system boot will not stop for a keyboard or disk
error; it will stop for all other errors.
w Memory
The category is for display-only and it is determined by POST Power On
Self Test of the BIOS.
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 640K.
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.
S1563-001-01 www.tyan.com 30
Expanded Memory
Expanded Memory (EMS) defines a 64 K 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.
S1563-001-01 www.tyan.com 31
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.
w Boot Sequence
This category determines which drive the computer searches first for the
disk operating system (i.e. DOS). Default value is A,C.
A,C System will first search for floppy disk drive then hard disk drive.
C,A System will first search for hard disk drive then floppy disk drive
S1563-001-01 www.tyan.com 32
w Boot Up Floppy Seek
During POST, the BIOS will determine if the floppy disk drive installed is
40 or 80 tracks. 360K type is 40 tracks while 720K, 1.2M and 1.44M
are all 80 tracks. Default value is Enabled
S1563-001-01 www.tyan.com 33
w Security Option
This category allows you to limit access to the system setup, or just
setup. Default value is 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
password is not entered at the prompt
w PS/2 Mouse Function
Enables or disables PS/2 mouse function. Default is Disabled.
w PCI/VGA Palette Snooping
The purpose of this option is to allow multiple VGA devices on
different busses in a system to have data written from CPU to each
set of palette registers of every video device. Default is disabled.
S1563-001-01 www.tyan.com 34
w Chipset Features
The DRAM timings can be altered from the default to optimize system
performance. Be aware though that these settings are sensitive to the
type and speed of DRAMs being used and can cause lockups or data
lost if set incorrectly. The default settings should work with most
DRAMs.
S1563-001-01 www.tyan.com 35
w Speculative Leadoff
The 430HX chipset is capable of allowing a DRAM read request to be
generated slightly before the address has been fully decoded. This can
reduce all read latencies.
More simply, the CPU will issue a read request and included with this
request is the place(address) in memory where the desired data is to be
found. This request is received by the DRAM controller. When enabled,
the controller will issue the read command slightly before it has finished
determining the address.
The default is disabled.
w Turn-Around Insertion
When this is enabled, the chipset will insert one extra clock to the
turn-around of back to back DRAM cycles.
The default is disabled.
S1563-001-01 www.tyan.com 36
w Memory Hole at 15M-16M
Some ISA cards may not function correctly when more than 16MB of
RAM is installed. If this is the case, then enable this option. Most ISA
card should work fine with this option disabled.
The default is disabled.

5.3 Advanced Chipset
w Shutdown to Port 92
When disabled, the 430HX forwards a Shutdown special cycle from
the host bus to the PCI bus. When enabled, the TXC will write a 1 to
I/O address 92 in response to a shutdown special cycle on the host bus.
The default is disabled.
w Memory Hole
This option lets you create a memory hole for either the 512-640KB
region or the 15-16MB region. The default is disabled.
w DRAM Timing
This setup question allows the system to be set to either optimal
settings for 60ns or 70ns DRAM, or to be set to manual. In this mode
the next nine options are made available for customizing the memory
timing.
S1563-001-01 www.tyan.com 52
♦Refresh Rate
Allows the refresh rate to be set according to the memory bus clock
(50mhz, 60mhz or 66mhz). The default depends on CPU speed.
♦LeadOff Timing
This bit controls additional DRAM timings. This includes: Read
LeadOff, Write LeadOff, RAS# Precharge, and Refresh RAS asser-
tion.
♦Speculative LeadOff
In this mode the DRAM controller read request is presented before the
final memory target (main memory, cache, or PCI) is decoded. This
results in a 1 HCLK increase in DRAM read leadoff latencies.
The default is disabled.
♦Turn-Around Insertion
When enabled the chipset inserts 1 extra clock of turnaround on the MD
lines after asserting memory write enable (MWE#).
S1563-001-01 www.tyan.com 53
♦Memory Address Drive Strength
This setup option allows the selection of memory address output buffer
drive affecting the MA(memory address) and MWE#(memory write
enale)pins. The default is 8ma/8ma.
♦Peer Concurrency
When enabled the CPU will be allowed to run DRAM/L2 cycles when
non-PHLD( PCI masters are running non-locked cycles targeting PCI
peer devices. The default is enabled.
♦ECC Test
This is a test mode described in the 430HX( Xcellerated Controller)
external design specification. This should be enabled only when using
ECC memory.
The default is disabled.

To reprogram the System BIOS, you must first do the following:
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 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.

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.
