Chapter 1: Introduction

1.1 Overview

The S1686S/D system board is a quality, high performance, single

(S1686S) or dual (S1686D) processing motherboard designed for Intel's

Pentium II microprocessors. This motherboard utilizes Intel's 440FX PCI

series chipset and supports CPU speeds of 233 to 300MHz. The S1686S/D, will

also support two Pentium Pro processors with Tyan riser cards (M2020).

The S1686S/D'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, 3D animation and video production.

This integrated system board achieves high reliability with numerous

features and yet is small enough to be supported in an "ATX" form-factor.

Some of the features included are: on-board dual channel PCI PIO (Mode 3 &

4), Multiword DMA (Mode 2) IDE, on-board floppy controller, and on-board

high speed I/O.

To provide you with the best board possible on the market, Tyan has also

incorporated into the board design the newest technologies available in the

industry. Some of these new features include the following:

1. LM78 System Monitoring (See Appendix for details, S1686S/D

ONLY)

2. Power off through software in Windows 95: This function allows the

user to turn off the ATX power supply and shut down the system by selecting

"Shut down" in the Start menu without hitting the power on/off switch on the

case. 3. Recovery after Power Interruption: When this function is set to

"Enabled" in the CMOS Setup, the power of the system will be automatically

turned on as soon as the power is recovered after an interruption (outage). The

user does not need to hit the power on/off switch on the case to turn on the

system power.

4. Wake on LAN: The S1686S/D provide the capability for the user to

turn on the system through another machine in the Local Area Network.

5. An on-board 12V to 5V Convertor gives support for keyboards with

built-in speakers, such as NMB Concert Master Keyboards.

Computer's web site located at http://www.tyan.com.

1.4 Manual Organization

Chapter 1 "Introduction" describes the features and performance of the

S1686S/D motherboard.

Chapter 2 "Installation" describes the procedures of setting up the system

board. Also refer to this chapter for detailed information about jumper

settings.

Chapter 3 "Installation and Removal of the CPU" gives detailed instruc-

tions on the installation and removal of the Pentium II--Active and

Passive CPU's.

If you encounter any problem, refer to Chapter 4 "Trouble-shooting",

which describes trouble-shooting procedures for the system.

Refer to Addendum A (AMI BIOS Setup) and Addendum B (Award

BIOS Setup) for the BIOS Setup requirements and the CMOS Configuration

Information, including instructions to change the password, to format a hard

disk, and to troubleshoot CMOS errors. Both AMI and Award BIOS docu-

ments are also available in the ADOBE Acrobat format. Please refer to our

Web page at http://www.tyan.com for these files.

1.5 Manual Conventions

In this manual, the following terms are used in reference to setting up jumpers:

1. When the term "close" is used, the pin (pins) specified for the jumper should

be connected (closed), and the circuit of the connecting pins will be shorted.

2. When the term "open" is used, the pin (pins) specified for the jumper should

not be connected, and the circuit of the connecting pins will not be shorted.

1.6 CPU types

Currently, Intel produces two types of Pentium II processors: the Active

(Boxed) Processor, and the Passive Processor. (Refer to the pictures shown on

Page 8). These two types of processors are essentially the same in design. The

only difference between these two types of processors lies in their cooling

methods. The Active Processor is equipped with a heatsink and cooling fan,

and the Passive Processor is equipped with a heat sink only. These two types of

CPUs provide the user with the same function, and should be installed in the

"Pentium II" slots on the motherboard. (Refer to Chapter 3 for the installation

and removal of Pentium II Processors).

NOTE ON S1686D: This motherboard is designed for Dual processors, but it

will accommodate a single CPU. However, when a single CPU configuration is

chosen, the Pentium II CPU should be installed in the Pentium II Primary slot

as mentioned in Chapter 3.

Chapter 2: Board Installation

2.1 Unpacking

2.1.1. Item Checklist

The motherboard package should contain the following:

• S1686S/D Motherboard • Motherboard User's manual

• One IDE 40 pin cable • BIOS User's manual

• One 34 pin floppy cable • One or Two CPU Retention Modules

2.1.2. Precautionary measures before handling the motherboard

Since the motherboard contains sensitive electronic components which can

easily be damaged by static electricity, the motherboard should be left in its

original packaging until it is ready to be installed.

Before you open the carton of your motherboard, do the following:

1. Make sure that you stand on an Anti-static mat. (Do not stand on a rug or

carpet.)

2. It is also strongly recommended that you wear an anti-static strap. (Anti-

static straps can be purchased at computer hardware stores.)

3. With the power supply plugged in and the system turned off, touch an un-

painted area of the system chassis before handling the motherboard or any com-

ponent. Remember to repeat the above steps whenever you handle the motherboard

or its components.

2.1.3. Proper handling of the motherboard

After opening the S1686S/D motherboard carton, remove the board by holding

its edges. Place it on a grounded anti-static surface with the component side up.

Inspect the board for damage. Do not touch the bottom of the board.

(Note:

DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAM-

AGED!)

2.2. Installation of the Motherboard

You are now ready to install your motherboard. The mounting hole pattern of

the S1686S/D matches the ATX system board specifications. Please install the

board in the chassis designed for a standard ATX board form factor.
