Preface
This Technical Information Manual provides information on the IBM PC 300PL (Types 6562 and 6592).
The manual, which is intended for developers who want to provide hardware and software products to
operate with these computers, provides in-depth information on how the computers work. Users of this
publication should have an understanding of computer architecture and programming concepts.
Manual Style
Because the PC 300PL (Type 6562) and (Type 6592) are similar, they will be referred to collectively as
PC 300PL computers throughout this manual, except in cases where differences between the two
computer types must be described.
In this manual, the use of the letter “h” indicates a hexadecimal number. Also, when numerical modifiers
such as “K”, “M” and “G” are used, they typically indicate powers of 2, not powers of 10. For example, 1
KB equals 1024 bytes (2 10), 1 MB equals 1048576 bytes (2 20), and 1 GB equals 1073741824 bytes
(230).
When expressing storage capacity, MB equals 1000 KB (1024000). The value is determined by counting
the number of sectors and assuming that every two sectors equals 1 KB. Depending on the operating
system and other system requirements, the storage capacity available to the user might vary.
Warning: The term
reserved describes certain signals, bits, and registers that should not be changed.
Use of reserved areas can cause compatibility problems, loss of data, or permanent damage to the
hardware. When the contents of a register are changed, the state of the reserved bits must be preserved.
When possible, read the register first and change only the bits that must be changed.
Some signals are abbreviated. A minus sign in front of a signal indicates that the signal is active low. No
sign in front of a signal indicates that the signal is active high.
