1. Introduction
1.1 Overview
The S1662 is a quality, high performance dual processor mainboard based
on the powerful Intel Pentium Pro microprocessors. This mainboard is
designed around the latest and fastest Intel 440FX chipset and can support
CPU speeds of 150MHz through 200MHz.
The S1662 supports EDO memory, Burst EDO, ECC and memory parity
checking.The S1662'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 is based
on a "Baby AT" form factor. Some of the features included are: onboard dual channel PCI IDE, on-board floppy controller, on-board high
speed I/O, Universal Serial Bus and on-board PS/2 mouse connector.
Flexibility and expandibility have been designed into the S1662. With I/O
and drive controller support built on-board, the five PCI and three ISA
(One ISA and one PCI as a shared slot) slots are free for add-on expansion
cards. With eight SIMM sockets, the S1662 can provide a very
flexible memory configuration of 8MB to 1024MB of RAM. With the
S1662's support for dual Pentium Pro processors, you can start a system
with just one CPU, and later add another, when more processing power is
required.

2. Board Installation
2.1 Unpacking
The mainboard package contains the following:
wS1662 Mainboard
wOne IDE 40 pin cable
wTwo serial cables
wOne parallel cable
wOne 34 pin floppy cable
wUser's Manual
wOptional PS/2 mouse cable
wOptional VRM(Voltage Regulator Module)
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 S1662 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
S1662 provides a 4-Pin header (J33) 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 440FX chipset doesn't support a de-turbo mode, but the S1662
has a connector (J30) 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
J29 in the correct direction.
11S1662-AT-001 http://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
J46.
3.8 Flash EEPROM-Jumper J9
The S1662 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.
J9 determines which type of EEPROM is used. This jumper has been set
to match the on board BIOS chip. The factory default for the S1662 is on
pins 1-2.
Refer to chapter 5 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 password or set the CMOS incorrectly, follow the instructions below.
a. Power off the system
b. Short jumper J5.
c. Wait for 5 seconds then remove the jumper from J5.
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.
12S1662-AT-001 http://www.tyan.com
3.10 DRAM Installation
The S1662 uses a 64-bit data path from memory to CPU and can
accommodate up to 1024 MB of RAM. The mainboard supports
standard, EDO (Extended Data Out) ECC(Error Correcting Code) and
BEDO(Burst EDO)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, 8,16, 32MBx32(x36) SIMMS.
wThe table on the following page shows some of the available memory
configurations.
Voltage ID for Older Pentium Pro CPU's: J7 and J10
Most Pentium Pro CPU's will program the VRM to output
the correct voltage it requires, so these jumper are not important
and should be left open. Some early versions of the Pentium Pro
cannot program the VRM so you have to set these jumper manually.
J7 and J10 each have eight pins and are numbered as follows.
5 6 7 8
Pin # 4--8 3-7 2-6 1-5
3.5V on on on on
3.4V on on on off
