Chapter1:Introduction

1.1 Overview

The S1686D system board--TAHOE 2I ATX, is a quality, high performance,

dual processing motherboard designed for Intel's latest generation Pentium II

microprocessors. This motherboard utilizes Intel's 440FX PCI series chipset and

supports CPU speeds of 233MHz to 300MHz. The S1686D, designed for a dual

system, will also support two Pentium Pro processors with Tyan riser cards.

The S1686D'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), 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. These new features include the following:

1. LM78 Power Monitoring (See Appendix for details).

2. Power off through Software for Windows 95: This function allows the

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

the "Shut Down" button on 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 a power interruption (outage).

The user does not need to hit the Power-on switch on the case to turn on the

system power.

4. Wake on LAN: The S1686D provides the capability for the user to turn

on a system through another server 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.

1.4 Manual Organization

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

S1686D system.

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 latest Pentium II--Boxed and

Passive CPU's.

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

which describes trouble-shooting procedures for the system.

Pin 1 2 3 4

Referto AddendumA(AMI BIOSSetup)andAddendumB(AwardBIOSSetup)

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 documents are also

available in the ADOBE Acrobat format. Please refer to the Web Page located at

ftp://ftp.tyan.com/manual/s1686da.pdf for AMI and ftp://ftp.tyan.com/manual/

s1686db.pdffor Award BIOSinformation.

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 Prototypes

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 cooling fan, and the Passive Processor

is equipped with a heat sink. These two types of CPUs provide the user with the

same function, and should be installed in the "Pentium II" (SEC) slots on the

motherboard. (Refer to Chapter 3 for the installation and removal of Pentium II

Processors).

Although the S1686D motherboard is designed for a dual system, it can also

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.

Chapter2:BoardInstallation

2.1 Unpacking

2.1.1.Item Checklist

The motherboard package should contain the following:

S1686DMotherboard

OneIDE 40pin cable

One 34 pin floppy cable

User's Manual

2.1.2.Precautionarymeasuresbeforehandlingthemotherboard

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 computer, do the following:

1. Make sure that you stand on an Anti-static mattress. (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 unpainted

area of the system chassis before handling the motherboard or any component.

Remember to repeat the above steps whenever you handle the motherboard or its

components.

2.1.3.Properhandlingofthemotherboard

After opening the S1686D 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 TOTHE BOARDIF ITHASBEEN DAMAGED!)

2.2. Installation of the Motherboard

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

S1686D matches the ATX system board specifications. Please install the board

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