Chapter 1: 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.
