1. INTRODUCTION 1.1. PREFACE Welcome to use the 5SMM motherboard. The motherboard is a Pipeline 512 KB CACHE Pentium ® Processor based PC / AT compatible system with ISA bus and PCI Local Bus, and has been designed to be the fastest PC / AT system. There are some new features allow you to operate the system with the performance you want.

Introduction Support Modem Ring-On. (Include internal Modem and external modem on COM A) Supports Wake-up on LAN (JP4). Supports 16 - 768 MB DRAM memory on board. Supports 3x168 pin 64/72 Bit DIMM module. Supports 2-channel Enhanced PCI IDE ports for 4 IDE Devices. Supports 1xCOM (16550), 1xLPT (EPP / ECP), 1x1.44MB Floppy port.
5SMM 1.3. PERFORMANCE LIST The following list of performance data 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. (The different Hardware & Software configuration will result in different benchmark testing results.)

5SMM 1.5. INTRODUCE THE PCI - BUS Connecting devices to a CPU local bus can dramatically increase the speed of I/O- bound peripherals with only a slight increase in cost over traditional systems. This price / Performance point has created a vast market potential for local bus products.
Hardware Installation 3. HARDWARE INSTALLATION 3.1. UNPACKING The mainboard package should contain the following: • The 5SMM mainboard. • USER’ S MANUAL for mainboard. • Cable set for IDE ¡ B Floppy. • CD for Mainboard Utility. The mainboard contains sensitive electric components which can be easily damaged by static electricity, so the mainboard should be left in its original packing until it is installed.
