ABOUT THIS MANUAL
The Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 3A:
System Programming Guide, Part 1 (order number 253668) and the Intel® 64 and
IA-32 Architectures Software Developer’s Manual, Volume 3B: System Programming
Guide, Part 2 (order number 253669) are part of a set that describes the architecture
and programming environment of all Intel 64 and IA-32 Architecture processors. The
other volumes in this set are:
• Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 1: Basic
Architecture (order number 253665).
• Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volumes
2A & 2B: Instruction Set Reference (order numbers 253666 and 253667).
The Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 1,
describes the basic architecture and programming environment of Intel 64 and IA-32
processors. The Intel® 64 and IA-32 Architectures Software Developer’s Manual,
Volumes 2A & 2B, describe the instruction set of the processor and the opcode struc-
ture. These volumes apply to application programmers and to programmers who
write operating systems or executives. The Intel® 64 and IA-32 Architectures Soft-
ware Developer’s Manual, Volumes 3A & 3B, describe the operating-system support
environment of IA-32 and Intel 64 processors. These volumes target operating-
system and BIOS designers. In addition, Intel® 64 and IA-32 Architectures Software
Developer’s Manual, Volume 3B, addresses the programming environment for
classes of software that host operating systems.
