CHAPTER 1 INTRODUCTION
Welcome to utilize 6254M mainboard, the Intel 440BX chipset supporting
both 66MHz and 100MHz Front Side Bus Pentium
II/III CPU. It also has the
built-in Yamaha YMF 724/740 3D PCI sound chip and Voodoo3 VGA chip.
The Yamaha YMF 724/740 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 plug any of VGA cards.
