6253M Mainboard
Chapter 1 Introduction
CHAPTER 1 INTRODUCTION
Welcome to use 6253M mainboard, the Intel 443BX chipset supporting both
66MHz and 100MHz Front Side Bus Pentium
II/III CPU. It also has the built-in
Yamaha YMF 740 3D PCI sound chip and Voodoo3 VGA chip. The Yamaha YMF
740 sound chip is using PCI interface which allows your computer to perform 3D
stereo sound. And the Voodoo3 3D VGA chip working with AGP interface technique
allows users to have 2D/3D display resolution without adding a VGA card
.
