Chapter 2 Major Changes in the ChorusOS 5.0 Documentation Set

This chapter describes major changes to the documentation set since the release of the ChorusOS 4.0 operating system.

ChorusOS Documentation Set Organization

The structure of the ChorusOS documentation set has been considerably reorganized to reflect groupings of books dedicated to specific types of users and their tasks:

• Installing, see "ChorusOS 5.0 Installation Collection".

• Developing applications; see "ChorusOS 5.0 Application Developer Collection".

• Administering; see "ChorusOS 5.0 System Administrator Collection".

• Designing Board Support Packages, or adding device drivers; see "ChorusOS 5.0 Target Platform Collection".

The manual pages collection, see "ChorusOS 5.0 Reference Manual Collection", is relevant to all four above types of users and their tasks.

ChorusOS Documentation Formats

ChorusOS 5.0 documents are delivered in AnswerBook, PDF, and HTML formats.

PostScript^TM files are no longer provided with the ChorusOS 5.0 documentation delivery, since PDF files are delivered which are smaller and easier to browse and print.

Mapping New ChorusOS 5.0 Books to ChorusOS 4.0 Books

The following sections describe how the information in the previous ChorusOS 4.0 (or ChorusOS 4.0.1 where relevant) documentation set maps to the new books in the ChorusOS 5.0 docset. For more information on the content of the new collections and books, see Chapter 3, Documentation Descriptions, Documentation Descriptions.
