INTRODUCTION TO THE 80286

The chapters in Part I are:

Chapter 2, "Architectural Features." This chapter discusses those features of the 80286 architecture that are significant for application programmers. The information presented can also function as an introduction to the machine for system programmers. Memory organization and segmentation, proces- sor registers, addressing modes, and instruction formats are all discussed.

Chapter 3, "Basic Instruction Set." This chapter presents the core instructions of the 8086 family.

Chapter 4, "Extended Instruction Set." This chapter presents the extended instructions shared by the 80186 and 80286 processors.

Part II of the book consists of a single chapter:

Chapter 5, "Real Address Mode." This chapter presents the system programmer's view of the 80286 when the processor is operated in Real Address Mode.

Part III of the book comprises chapters 6 through 11. Aimed primarily at system programmers, these chapters discuss the more advanced architectural features of the 80286, which are available when the processor is. in Protected Mode. Details on memory management, protection mechanisms, and task switching are provided.

The chapters in Part III are:

Chapter 6, "Virtual Memory." This chapter describes the 80286 address translation mechanisms that support virtual memory. Segment descriptors, global and local descriptor tables, and descriptor caches are discussed.

Chapter 7, "Protection." This chapter describes the protection features of the 80286. Privilege levels, segment attributes, access restrictions, and call gates are discussed.

Chapter 8, "Tasks and State Transitions." This chapter describes the 80286 mechanisms that support concurrent tasks. Context-switching, task state segments, task gates, and interrupt tasks are discussed.

Chapter 9, "Interrupts, Traps and Faults." This chapter describes interrupt and trap handling. Special attention is paid to the exception traps, or faults, which may occur in Protected Mode. Interrupt gates, trap gates, and the interrupt descriptor table are discussed.

Chapter 10, "System Control and Initialization." This chapter describes the actual instructions used to implement the memory management, protection, and task support features of the 80286. System registers, privileged instructions, and the initial machine state are discussed.

Chapter 11, "Advanced Topics." This chapter completes Part III with a description of several advanced topics, including special segment attributes and pointer validation.
