Introduction

Overview

The Trinity KT-A is a quality, high performance motherboard designed for Socket A
AMD

 Duron™ and Athlon™ microprocessors. The Trinity KT-A utilizes the VIA

KT-133A chipset with AwardBIOS™, can support Duron CPU speeds of 600 MHz
through 800 MHz and Athlon CPU speeds of 750 MHz through 1+ GHz with 200/
266 MHz system bus interface speed. For CPU compatibility information and
updates, check the Tyan website for more details: 

http://www.tyan.com

The Trinity KT-A motherboard provides high performance capabilities that are ideal
for a wide range of demanding applications such as CAD, CAM, CAE, desktop
publishing, 3D modeling, animation, and video production.

This integrated high-performance system board in an ATX form factor offers more
features and expandability than other ATX boards in its class.  Some of the features
included are onboard UltraDMA 33/66/100, and (optionally) onboard digital link sound
with VIA 686B sound chipset utilizing the AC’97 audio codec.

Flexibility and expandability have also been designed into the Trinity KT-A. With I/O
and drive controller support built onboard (along with the many onboard features
previously mentioned), the AGP 1x / 2x / 4x slot, six PCI slots, and ISA slot (shared
with a PCI) are free for more add-on expansion cards.

Remember to take a look at Tyan’s website located at

. There you

can find information on all of Tyan’s products along with FAQs, distributors list,
drivers, and BIOS setting explanations.
