1. INTRODUCTION
1.1. PREFACE
Welcome to use the 686DLX motherboard. The motherboard is a Dual
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.
