Introduction
1. INTRODUCTION
1.1. PREFACE
Welcome to use the 686BX motherboard. It 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.
This manual also explains how to install the motherboard for operation, and
how to set up your CMOS CONFIGURATION with BIOS SETUP program.
