What you'll find in this guide

The QNX Neutrino User's Guide is intended for all users of a QNX Neutrino system, from system administrators to end users. This guide tells you how to:

• Use the QNX Neutrino 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 Neutrino system prompt or Photon login 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 Neutrino machine, etc.

The Neutrino User's Guide is intended for programmers who develop Neutrino-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.

We assume that QNX Neutrino is already installed and running on your computer. If you've installed the QNX Software Development Platform (which includes the QNX Momentics Tool Suite), see the Welcome to the QNX Software Development Platform guide for an overview of the system and the documentation. 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 in the QNX Momentics Tool Suite, 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.

Typographical conventions

Throughout this manual, we use certain typographical conventions to distinguish technical terms. In general, the conventions we use conform to those found in IEEE POSIX publications. The following table summarizes our conventions:

We use an arrow (→) in directions for accessing menu items, like this:

You'll find the Other... menu item under Perspective-->Show View.

We use notes, cautions, and warnings to highlight important messages:

---

Notes point out something important or useful.

---

---

Cautions tell you about commands or procedures that may have unwanted or undesirable side effects.

---

---

Warnings tell you about commands or procedures that could be dangerous to your files, your hardware, or even yourself.

---

Note to Windows users

In our documentation, we use a forward slash (/) as a delimiter in all pathnames, including those pointing to Windows files.

We also generally follow POSIX/UNIX filesystem conventions.

Navigation buttons

At the top and bottom of our HTML docs, you'll see some or all of these buttons:

Use this button:	To move:
	To the previous part of the document.
	“Up” in the document: In a prose book, this typically takes you to About This Guide. In a reference book, it takes you to the listing of items that start with a given letter. For example, if you're looking at the docs for abs(), this button takes you to the listing of the functions that start with A.
	To the keyword index.
	To the next part of the document.
