1. Preface
1.1 About This Book
This book describes the features and operation of the IBM 133 PCI-X Bridge R2.0. While every effort has
been made to ensure that all information contained herein is as accurate as possible, users of this document
should be aware that it is subject to change by IBM without notice. Any comments, corrections, and recom-
mended additions to improve this book may be forwarded to the address inside the front cover.
1.2 Who Should Read This Manual
This document is designed for engineers and system designers interested in implementing PCI-X capable
systems or adapters using a PCI-X to PCI-X transparent bridge device.
It is assumed that the reader is acquainted with the PCI and PCI-X bus specifications. For details about bus
protocols and general bridge architecture, see the documents listed in
1.3 Document Contents
1.4 Conventions and Notation
Throughout this document, bit notation is non-IBM, meaning that bits and bytes are numbered in descending
order from left to right. Thus, for a four-byte word, bit 31 is the most significant bit and bit zero is the least
significant bit.
