1. Introduction
1.1 Overview
The S1564S/D is a quality, high performance single or dual processor
mainboard based on the powerful Intel Pentium microprocessors. This
mainboard is designed around the Intel 430HX chipset and can support
CPU speeds of 75MHz through 233MHz and beyond. The S1564S is
single processor mainboard and the S1564D is a dual processor
mainboard.
The S1564 incorporates a switching power supply that allows support for
single or dual Pentium/Pentium MMX processors, single Cyrix proces-
sors, and single AMD processors.It also supports EDO/FPM memory,
ECC memory and memory parity checking.The S1564'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 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 S1564. 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 S1564 can provide a very
flexible memory configuration of 8MB to 512MB of RAM. With the
S1564D'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.
To provide you safer way of operating your system, Tyan has also
incorporated LM78 (Option) System Hardware Monitor and Intel
LANDeskTM Client Manager (LDCM) into the S1564S/D board design
(See Appendix for details).

2. Board Installation
2.1 Unpacking
The mainboard package should contain the following:
• One S1564S or S1564D Mainboard
• One IDE 40 pin cable
• Two serial cables (on bracket)
• One parallel cable (on bracket)
• One 34 pin floppy cable
• One 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 pluged 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 up.
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.
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 S1564S/D matches the "Baby AT" system board spec. It is assumed
that the chassis is for a standard IBM XT/AT 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. When replacing, you should use the same
model.
3.4 Speaker Connector Installation
S1564 provides a 4-Pin header (J23) to connect the speaker. The polarity
can go either way.
3.5 Turbo Switch
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 S1564
has a connector (J26) for the cable that may come with the case.
3.6 Turbo LED Connector Installation
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.

13S1564-001-01 www.tyan.com
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.
3.8 Flash EEPROM-Jumper J48
The S1564 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.
Refer to chapter 6 for Flash EEPROM upgrade procedures.
3.9 Hardware CMOS & Password Reset
(The following steps are valid provided the board has a DS12887A RTC)
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. Short jumper J46.
c. Wait for 5 seconds then remove the jumper from J46.
d.Then power on the system again.
By doing the above procedures, your password will be erased and the CMOS
will be reset to the BIOS defaults.

14S1564-001-01 www.tyan.com
3.10 DRAM Installation
The S1564 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.
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.
wThe table below shows some of the available memory configurations.

3.11 CPU Installation
Many types of Pentiums (75 thru 233 MHz) and Cyrix/AMD CPUs can
be used on the S1564. Please refer to the previous pages for the correct
CPU jumper settings for your board.
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
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.
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.

3.12 Cache Memory
The S1564 comes with 512Kb of L2 synchronous pipeline burst SRAM.
The S1564's L2 cache is surface mounted and can be enabled or dis-
abled through the BIOS setup.
wThe BIOS will auto detect the cache size so a you don't need to change
any jumpers.
wThe mainboard has an 11 bit tag built on board so cachability of main
memory is to 512MB.

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.
Pentium Mainboard PCI Bus
Internal Clock Clock Clock
75 MHz 50 MHz 25 MHz
90 MHz 60 MHz 30 MHz
100 MHz 66.67 MHz 33 MHz
120 MHz 60 MHz 30 MHz
133 MHz 66.67MHz 33 MHz
150 MHz 60 MHz 30 MHz
166 MHz 66.67 MHz 33 MHz
200 MHz 66.67 MHz 33 MHz
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.

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.
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.
