2. Board Installation
2.1 Unpacking
The mainboard package should contain the following:
wS1570Mainboard
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 com-
ponent. 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. 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 S1570 matches the Baby-AT system board spec. It is assumed that the
chassis is for a standard Baby-AT mainboard form factor.

3.3 CMOS RTC
The TX chipset includes a Real Time Clock circuit. It provides the date and
the time for the system. Normally the life span of a RTC battery is 5 years.
If the battery for the RTC is low, it will prevent your system from
POSTing and you will not get a display. If this occurs, you will need to
replace the battery with another 3volt lithium battery(Duracell DL2032).
3.4 Speaker Connector Installation
The S1570 provides a 4-Pin header to connect the speaker. The speaker is
connected to pins 24-27 of jumper block J8.
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 pins
22 and 23 on jumper block J8.
3.8 Flash EPROM-Jumper JP16
The S1570 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.
JP16 determines which type of EPROM is used. This jumper has been set
to match the on board BIOS chip. The factory default for the S1570 is on
pins 1-2. Depending on the type of EPROM used, some boards will have
JP16 on pins 2-3.

14S1570-001-01 http://www.tyan.com
Refer to chapter 5 for Flash EPROM upgrade procedures.
3.9 Hardware CMOS & Password Reset: JP38
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. Jumper JP38 to pins2 and 3.
c. Wait for 2 seconds then return the jumper to pins 1 and 2.
d.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.

15S1570-001-01 http://www.tyan.com
3.10 DRAM Installation
The S1570 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.
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. 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 SIMMs.
wSIMM bank 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.
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.
You can use SIMM bank 0 with DIMM bank 1.
You can use SIMM bank 1 with DIMM bank 0.
wIf you use 4Mx64 DIMMs you cannot use DRAM bank 2.
wWe do not recommend using DRAM bank 2 along with DIMMs.

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.
3.11 CPU Installation
Several types of CPUs (75 thru 200MHz) can be used on S1570.
Please refer to section 3.2 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.
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.
