PCI Bus Overview

Part 1, The PCI Bus describes the PCI bus and tells you how it works with Power Macintosh computers:

PCI Bus Overview describes the PCI standard and summarizes the ways that Power Macintosh computers comply with it.
Data Formats and Memory Usage defines the formats in which data moves over the PCI bus and the memory spaces reserved for PCI use.

System Startup by Open Firmware

Part 2, The Open Firmware Process describes the startup process in Power Macintosh computers that support devices attached to the PCI bus and run
Mac OS. The first chapter in Part 2 describes how the Macintosh boot process has changed and how ROM and memory mapping differ since the introduction of the iMac computer. This is essential reading for PCI card and peripheral device developers interested in participating in the boot process on the latest Macintosh computer models.

Introduction to the NewWorld Architecture describes how the NewWorld Architecture works from an organizational and execution flow standpoint and describes differences from older architectures.
Startup and System Configuration describes how PCI-compatible Macintosh computers recognize and configure peripheral devices connected to the PCI bus.
PCI Open Firmware Drivers discusses Open Firmware drivers, which control PCI devices during the Open Firmware startup process.

Native PowerPC Drivers

Part 3, Native Device Drivers tells you how to design and write runtime PCI card drivers for Power Macintosh computers. These drivers are called native because they are written for execution by the native instruction set of the PowerPC microprocessor. Part 3 consists of these chapters:

Native Driver Overview presents the general concepts and framework applicable to PCI drivers for PowerPC Macintosh computers.
Finding, Initializing, and Replacing Drivers discusses what PCI driver and card designers can do to improve the compatibility of their products.
Writing Native Drivers gives you details of native driver design and coding, including how to use services provided by the Macintosh Driver Loader Library.
Driver Loader Library describes the Driver Loader Library (DLL), a CFM shared-library extension to the Macintosh Device Manager.
Name Registry describes the Mac OS data structure that stores device information extracted from the PCI device tree.
Driver Services Library details the general support that Mac OS provides for device drivers, including interrupt and timing services.
Expansion Bus Manager discusses a collection of PCI bus-specific system services available to native device drivers.
Graphics Drivers describes the calls serviced by typical display drivers.
Network Drivers describes the construction of a sample network driver.
SCSI Drivers describes the construction of a sample native SCSI Interface Module (SIM) compatible with Macintosh SCSI Manager 4.3.

Appendixes

Four appendixes follow the main part of this book.

Big-Endian and Little-Endian Addressing discusses the theory and problems of handling mixed-endian formats.
Graphic Memory Formats describes the ways that graphic information and video frames are stored in PCI-based Power Macintosh computers.
PCI Header Files describes the PCI header files and lists all the routines and data structures documented in this book.
Abbreviations lists the abbreviations and acronyms used in this book.
