Introduction 1- 1 1. INTRODUCTION 1.1. PREFACE Welcome to use the GA - 686LX motherboard. The motherboard is a Pentium II 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.
GA-686LX 1- 2 q ATX form factor, Double stack I/O connector, 4 layers PCB. 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.
