6BA 1- 1 1. INTRODUCTION 1.1. PREFACE Welcome to use the 6BA motherboard. It is a Pentium II / III / Celeron Processor based PC / AT compatible system with AGP / PCI / ISA Bus, and has been designed to be the fastest PC / AT system. There are some new features allow you to operate the system with just the performance you want.
Introduction 1- 2 1.3. PERFORMANCE LIST The following performance data list is the testing results of some popular benchmark testing programs. These data are just referred by users, and there is no responsibility for different testing data values gotten by users.
