PREFACE
The iRMX 86 Operating System is a software package that provides
real-time, multitasking capabilities for Intel iSBC 86 single board
computers and any other iAPX 86- or iAPX 88-based microcomputers. This
manual contains information that is separately described for system
programmers. In Chapter 1, the terms system and application programmers
are defined, and the reasons for making a distinction between them are
explained. The remaining chapters are devoted to various kinds of
information that can, if you so desire, be hidden from application
programmers.
The following manuals provide additional information that may be helpful
to readers of this manual.
