About the QNX OS User's Guide

QNX SDP8.0User's GuideUser

The QNX OS User's Guide is intended for all users of a QNX OS system, from system administrators to end users.

This guide tells you how to:

  • Use the QNX OS runtime environment, regardless of the kind of computer it's running on (embedded system or desktop). Think of this guide as the companion how-to doc for the Utilities Reference. Assuming there's a system prompt waiting for input, this guide is intended to help you learn how to interact with that prompt.
  • Perform such traditional system administration topics as setting up user accounts, security, starting up a QNX OS machine, etc.

This User's Guide is intended for programmers who develop QNX OS-based applications, as well as OEMs and other resellers of the OS, who may want to pass this guide on to their end users as a way to provide documentation for the OS component of their product.

Note:
  • Your system might not include all of the things that this guide describes, depending on what software you've installed. For example, some utilities are included with the OS, and others are included in a specific Board Support Package (BSP).

    The online version of this guide contains links to various books throughout our entire documentation set; if you don't have the entire set installed on your system, you'll naturally get some bad-link errors (e.g., File not found).

  • Disable PnP-aware OS in the BIOS.
