vi Technical Information Manual

Preface
This Technical Information Manual provides information on the IBM IntelliStation M Pro (Type 6898). This
manual is intended for developers who want to provide hardware and software products to operate with
their computer. It provides in-depth information on how the computer works. Users of this publication
should have an understanding of computer architecture and programming concepts.
Manual Style
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.
