1. Introduction
1.1 Overview
The S1469 is a quality, high performance mainboard based on the power-
ful Intel Pentium microprocessors. This mainboard is designed around the
latest and fastest Intel 430VX chipset and can support CPU
speeds of 75MHz through 200MHz. S1469 will also support the Cyrix
M1/6x86 CPU's and the Intel multimedia Pentium P55C.
The S1469'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 S1469. With I/O
and drive controller support built on-board, the four PCI and four ISA
(One ISA and one PCI as a shared slot) slots are free for any add-on
expansion cards.
Remember to take a look at Tyan Computers web site located at
http://www.tyan.com. Here you can find information on all of Tyan's
products along with FAQ's, distributors list, drivers and CMOS setting
explanations.
Notice
This board uses the Intel 430VX chipset. According to Intel , the USB
function in this chipset is not guaranteed because compatibility tests
cannot be conducted for USB at this time due to no availability of
such devices.

2. Board Installation
2.1 Unpacking
The mainboard package should contain the following:
wS1469 Mainboard
wOne IDE 40 pin cables
wTwo serial cables
wwOne parallel 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.
Touch an unpainted area of the system chassis befor handling the mainboard
or any component. Doing so discharges the static charge your body may
have built.
After opening the mainboard carton, extract the system board 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 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 S1469 matches the "Baby AT" system board spec. It is assumed that the
chassis is designed for a standard IBM XT/AT.

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
S1469 provides a 4-Pin header (J41) 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.
You can connect the chassis turbo switch to J42 on the mainboard. The
430VX chipset doesn't support a hardware turbo function so this switch will
only turn on or off the turbo LED.
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
J50 in the correct direction.

13S1469-001-01http://www.tyan.com
3.7 Hardware Reset Switch Connector Installation
The RESET switch on your cases' display panel provides users with the
HARDWARE RESET functinon 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
J49.
3.8 Flash EPROM-Jumper J54
The S1469 uses flash memory to store BIOS programs. It can be updated
as new versions of the BIOS becomes available. The flash utility will guide
you through the process step by step.
J54 determines which type of EPROM is used. This jumpers has been set
to match the on board BIOS chip. The factory default for the S1469 is on
pins 1-2. Depending on the type of EPROM used, some boards will have
J54 on pins 2-3.
Refer to chapter 5 for Flash EPROM 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 J43.
d. Wait for 5 seconds then remove the jumper from J43.
e.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 default.

14S1469-001-01http://www.tyan.com

The S1469 uses a 64-bit data path from memory to CPU and can
accommodate up to 128 MB of RAM. The mainboard supports Fast
Page Mode, and EDO (Extended Data Out) 72 pin SIMMs.
SDRAM(Synchronous) are also supported in the DIMM slots. DIMM's
must be of the unbuffered variety. All installed memory will be automati-
cally 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 and 8MBx32 SIMMs.
wSIMM bank 0 and 1 can use either double or single sided SIMMs.
wTwo SIMMs or One unbuffered DIMM must be installed for the system
to POST.
wSDRAM DIMMs can be installed one at a time.
wThe mainboard supports 1, 2 and 4Mx 64 DIMM modules.
wSIMM bank 0 and DIMM bank 0 cannot be used at the same time.
SIMM bank 1 and DIMM bank 1 cannot be used at the same time.

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.
When the CPU is installed, the lever should snap into place at the
side of the socket.
3.11 CPU Installation
Several types of CPUs (75 thru 200MHz) can be used on S1469.
Please refer to the previous pages for the correct CPU jumper settings for
your board.
wThe CPU is a sensitive electronic component and it can be easily
damaged by static electricity. Do not touch the CPU pins with your
fingers.
wWhen installing the CPU into the socket, match the CPU pins to the
socket pins.
wBefore the CPU is installed, the mainboard must be placed on a flat
plane in order to avoid being broken by the pressure of CPU insertion.
wA cooling fan and heat sink assembly is required to protect the
CPU from being damaged.

16S1469-001-01http://www.tyan.com
3.12 Upgrading Cache Memory
The S1469 has 256Kb of on-board pipelined burst SRAM and
can be upgraded to 512Kb by adding a Tyan approved 256Kb
cache module. Please refer to your vendor for the approved
upgrade modules.
wRefer to page 9 for the cache jumper settings.
wWhen using the "COAST" module, the Tag RAM socket must be
empty. You must also open jumper J20.
wOnly use Tyan approved "COAST" modules when upgrading.
wThe "COAST Module" will only fit in the "Coast Socket" one way and
should install easily.
wwYou cannot disable the onboard cache and install a 512Kb "COAST"
module to get 512Kb of cache. The onboard cache is always used.

17S1469-001-01http://www.tyan.com
3.13 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
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, the user should check everything
again, and prepare to power-on the system.
