  • Page 3: Introduction

    Introduction INTRODUCTION 1.1. PREFACE Welcome to use the 6BXU motherboard. It is a Pentium II Processor based PC / AT compatible system with AGP / PCI / SCSI / 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.
  • Page 4: Performance List

    6BXU 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. (The different Hardware & Software configuration will result in different benchmark testing results.)

  • Page 8: What Is Agp

    6BXU 1.6 What is AGP The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI bridge device that supports an AGP port. The main purpose of the AGP port is to provide fast access to system memory. The AGP port can be used either as fast PCI port (32-bits at 66MHz vs. 32-bits at 33MHz) or as an AGP port which supports 2x data-rate, a read queue, and side band addressing.

    6BXU The system bus speed can be set to 66MHz or 100MHz form the jumper (JP5). The user can change the DIP SWITCH (SW) selection to set up the CPU speed for different processors. The CPU speed must match with the frequency RATIO and Front Side Bus (FSB) speed.
  • Page 19: Speaker Connector Installation

    Hardware Installation There're RTC & CMOS SRAM on board; they have a power supply from external battery to keep the DATA inviolate & effective. The RTC is a REAL- TIME CLOCK device, which provides the DATE & TIME to system. The CMOS SRAM is used for keeping the information of system configuration, so the system can automatically boot OS every time.
  • Page 20: Scsi Device Installation

    6BXU The main board supports PS/2 Mouse (J1). The BIOS will auto detect whether the PS/2 Mouse is installed or not & assign IRQ12 for PS/2 Mouse port if it is installed. After installing the peripheral device, the user should check everything again, and prepare to power-on the system.
