1. Introduction
1.1 Overview
The S1564S/D is a quality, high performance single or dual processor
mainboard based on the powerful Intel Pentium microprocessors. This
mainboard is designed around the Intel 430HX chipset and can support
CPU speeds of 75MHz through 233MHz and beyond. The S1564S is
single processor mainboard and the S1564D is a dual processor
mainboard.
The S1564 incorporates a switching power supply that allows support for
single or dual Pentium/Pentium MMX processors, single Cyrix proces-
sors, and single AMD processors.It also supports EDO/FPM memory,
ECC memory and memory parity checking.The S1564'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 and 3D animation.
This integrated system board achieves the highest reliability and yet is
small enough for all of its features to be supported in a "Baby-AT" form-
factor. Some of the features included are: on-board dual channel PCI
IDE, on-board floppy controller, on-board high speed I/O, and support for
pipeline-burst SRAM.
Flexibility and expandibility have been designed into the S1564. With I/O
and drive controller support built on-board, the four PCI and five ISA
(One ISA and one PCI as a shared slot) slots are free for any add-on
expansion cards. With eight SIMM sockets, the S1564 can provide a very
flexible memory configuration of 8MB to 512MB of RAM. With the
S1564D's support for dual Pentium processors, you can start a system
with just one CPU, and later add another, when more processing power is
required.
To provide you safer way of operating your system, Tyan has also
incorporated LM78 (Option) System Hardware Monitor and Intel
LANDesk
TM
Client Manager (LDCM) into the S1564S/D board design
(See Appendix for details).
