IBM PC CONVERTIBLE Technical Reference page 4

Preface
The IBM PC Convertible Technical Reference consists of two
volumes. Volume 1 describes the hardware design and
provides interface information for the IBM PC Convertible.
Volume 1 also has information about the basic input/output
system (BIOS) and programming support. Volume 2 contains
the BIOS listings.
The information in these volumes is both descriptive and
reference-oriented and is intended for hardware and software
designers, programmers, engineers, and other interested
persons who need to understand the design and operation of
the IBM PC Convertible. These users should be familiar with
the use of the IBM PC Convertible and understand the
concepts of computer architecture and programming.
Volume 1 has five sections:
• Section 1, "Introduction" is an overview of the system and
the available options.
• Section 2, "System Unit" describes each functional part of
the base system. This section also contains the description
of the interfaces. Programming considerations are
supported by command code and register descriptions.
• Section 3, "System Options" describes each available
option.
• Section 4, "System BIOS and Usage" describes the basic
input/output system (BIOS) and its use. This section also
contains the software interrupt listing, a system memory
map, descriptions of vectors with special meanings, and a
set oflow-storage maps. In addition, Section 4 describes
keyboard encoding and usage.
• Section 5, "Compatibility with the IBM Personal
Computer Family" describes programming concerns for
maintaining compatibility among the IBM PC
Convertible system and the other IBM Personal
Computers.
