1.1 Overview

The S1680S system board--TAHOE -AT 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 CPU
speeds of 233MHz to 300MHz. The S1680S will also support the Intel Pentium
Pro Processors with a Tyan Riser Card (M2020). The 440FX PCIset also supports
up to 1GB (1024MB) of system memory utilizing either EDO, FPM or Parity with
ECC.
The S1680S' 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 a Baby-AT system. Some of
the features included are: on-board dual channel PCI PIO (Mode 3 & 4), on-board
high speed I/O, USB connectors for up to 2 ports, Dallas RTC (Real Time Clock),
and a host of built-in extras.
The S1680S board is built to be both flexible and expandable. With I/O and
drive controller support built on-board, the five 32-bit PCI Bus Master and four
16-bit ISA slots (one shared/eight usable slots) are available for add-on expan-
sion cards.
