1. INTRODUCTION
1.1. PREFACE
Welcome to use the 6BMM motherboard. It is a PentiumII / Celeron
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.

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. When the 2x-data rate is used, the port can transmit
data at 533MB/sec (66.6*2*4). The read-queue can be used to pipeline reads –
removing the effects of the reads-latency. Side band addressing can be used to
transmit the data address on a separate line in order to speed up the
transaction.
