Chapter 1: Introduction

1.1 Overview

The S1684S/SA* system board--TAHOE -(A)* ATX is a quality, high

performance motherboard designed for Intel's latest generation of Pentium II

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

and supports Pentium II CPU speeds of 233MHz to 300MHz. The S1684S/SA*

will also support the Intel Pentium Pro Processors with a Tyan Riser Card

(M2020).

The S1684S/SA'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, yet it 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.

The S1684S/SA board is built to be both flexible and expandable. With I/

O and drive controller support built on-board, the four 32-bit PCI Bus Master

and four ISA slots (one shared/seven usable slots) are available for add-on

expansion cards.

In order to provide you with more detailed information about board

components and their functions, Tyan has designed the Web Page and clickable

motherboards for your reference. Please refer to Tyan Computer's web site

located at http://www.tyan.com for more information about your S1684S/SA*

board. Here you will also find information on all of Tyan's products along with

FAQ's, distributors, drivers and CMOS setting explanations.

Note on S1684SA model (with sound)

(* The S1684S motherboard does not have the built-in Vibra 16 Audio Feature.

The S1684SA model is equipped with the Vibra 16 Audio System. Along with

your Vibra 16 CL/X Drivers, the 1684SA motherboard also has a CD-ROM

Connector, Tel/Modem Connector, Sound Port and WaveTable Connector on-

board. Please refer to the Motherboard Layout on Page 10 for locations. )

Please refer to Addendum C for more information on installing, upgrading and

configuring your on-board sound chip and its features.

1.4. Manual Organization

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

S1684S/SA 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 instructions on

installation and removal of the latest Pentium II--Active and Passive CPUs.

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

describes trouble-shooting procedures for the system.

1.5. Manual Conventions

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

jumpers:

1. When the term "Close" or "On" is used, the pin (pins) specified for the

jumper should be connected (closed), and the circuit of the connecting pins will

be shorted.

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

(Award BIOS CMOS Setup) for the 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 Setup documents are also available in the Adobe Acrobat

format. Please refer to the Web Page located at ftp://ftp.tyan.com/

s1684saa.pdf for AMI and ftp://ftp.tyan.com/s1684sab.pdf for Award

BIOS information.

2. When the term "Open", "Shorted", or "Off" is used, the pin (pins)

specified for the jumper should not be connected, and the circuit of the connect-

ing pins will not be shorted.

1.6. CPU types

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

(or Active) 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 Boxed (Active) Processor is equipped with

a CPU cooling fan and heatsink built in with the CPU, 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 S1684SA board. (Refer to Chapter 3 for the

installation and removal of Pentium II processors.)

2.1 Unpacking

2.1.1. Item Checklist

The mainboard package should contain the following:

S1684S:• S1684S/SA motherboard • User's manual

• One IDE 40 pin cable • One 34-pin floppy cable

• BIOS User's manual • One Retention module

S1684SA(adds): • Sound Addendum C • Tyan Vibra 16 CD-ROM

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 kept in its

original packaging until time of installation.

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 your local 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 follow the above procedure whenever you

handle the motherboard or its components.

2.1.3. Proper handling of the motherboard

After opening the 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 board matches the ATX system board specifications. Please install
