http://www.tyan.com/support/html/socket_7_compatibility.html. TheTomcat
i810 also has 100MHz Front Side Bus support, which allows you to take full
advantageof 100MHz SDRAM memorymodules.
The S2054 motherboard, provides high performance capabilities that are ideal
for a wide range of demanding applications such as CAD, CAM, CAE, desktop
publishing, 3D animation, and video production.
This integrated high-performance system board in a micro-ATX form factor
offers more features and expandability than other micro-ATX boards in its
class. Some of the features included are onboard UltraDMA/66, onboard
digital link sound withAC-97 Codec, onboard VGAport, built-in Intel 3D
Graphics accelerator, onboard 4MB display cache for enhanced graphics
performance, and onboard Digital Flat Panel Transmitter for LCD monitor.

With I/O and drive controller support built onboard (along with the many
onboard features previously mentioned), the four PCI slots are free for more
add-on expansion cards.

http://www.tyan.com.There you can find information on all of TYAN’s
products along with FAQs, distributors list, drivers, and BIOS setting explana-
tions.
Icons
In order to help you navigate this manual and set up your system, we have
added several icons to our format.
This icon alerts you to particularly important details regarding the
setup or maintenance of your system. This icon often appears next
to information that may keep you from damaging your board or
system. While we will often point out the most vital paragraphs in a
chapter, you should always read every word in the text. Failing to do so can
lead to exasperation and expense.
Wherever possible, we have included step-by-step instructions for
setting up your system, which are indicated by this icon. However, it
is in your best interest to read an entire section (and perhaps the
entire manual) before you begin to fiddle with your motherboard.
While we have alerted you to potential dangers in several places in
the manual with this icon, these warnings should not be regarded as
the whole of your safety regimen. Never forget that computers are
electrical devices, and are capable of delivering a shock. Prevent
damage to yourself and to your board: always ensure that your system is
turned off and unplugged whenever you are working with it, and that you are
equipped with a static safety device.

TechnicalSupport
If a problem arises with your system, you should turn to your dealer for help
first. Your system has most likely been configured by them, and they should
have the best idea of what hardware and software your system contains.
Hence, they should be of the most assistance. Further, if you purchased your
system from a dealer near you, you can actually bring your system in to them
to have it serviced, instead of attempting to do so yourself (which can have
expensive consequences).
