About This Guide

This guide describes how to install Version 4.0 of the Digital UNIX® operating system on all supported processors and single-board computers.

Digital has changed the name of its UNIX operating system from DEC OSF/1 to Digital UNIX. The new name reflects Digital's commitment to UNIX and its conformance to UNIX standards.

This guide describes how to prepare your system for installation, how to boot the system from the distribution media, and how to perform the installation procedure.

This guide also explains how to install the Digital UNIX worldwide language support software after installing the base operating system.

In Digital UNIX Version 4.0 you can use the update installation procedure to update from Digital UNIX Version 3.2C, 3.2D-1, or 3.2D-2 to Digital UNIX Version 4.0. The installupdate program preserves your user and data files and any system setup you may have done.

The wwinstallupdate procedure updates Version 3.2C, 3.2D-1, or 3.2D-2 Worldwide Language Support software to Version 4.0

If your system is delivered to you with Factory Installed Software (FIS), the software necessary to get your system up and running has already been installed for you at one of Digital's manufacturing facilities. Follow the instructions for entering system information in the FIS Quick Reference Card delivered with your system, and then refer to Chapter 6 in this guide for instructions on how to configure and set up your system.

Audience

This book is intended for anyone installing the Digital UNIX base operating system software or Digital UNIX worldwide language support software. Before starting an installation, you must:

• Read the documentation supplied with your processor or single-board computer

• Read the current version of the Digital UNIX Release Notes

• Understand how to load and unload the installation media and know which disks are needed during the installation

• Know the names and unit numbers of your disk devices

• Have a basic understanding of the file system and commands

New and Changed Features

The following are new and changed installation features in Digital UNIX Version 4.0:

• This guide has been revised to document the new user interfaces to the full installation procedure. If your system has graphics capabilities and more than 32 MB of memory, a graphical user interface is presented when you invoke the full installation. If your system does not have graphics capabilities, a text-based interface (a question and answer session) is presented.

• The names of the full installation procedures have been changed to: default installation (formerly known as the basic installation) and custom installation (formerly known as the advanced installation).

• All information required by the full installation procedure is entered before any changes are made to your system. Both user interfaces let you go back and change your answers before you confirm that you are ready to begin the full installation procedure.

• Both user interfaces have online help. The graphical user interface has a series of help buttons; clicking on these help buttons displays overview, task, and reference information for the installation setup process. The text-based interface lets you enter a question mark (?) at each question if you need more information.

• Free disk space in each file system is calculated automatically as software subsets are selected. This allows you to ensure that file systems are large enough to hold the software you want to install.

• Software subset dependencies are checked and resolved automatically.

• If your system has graphics capabilities, a SysMan Configuration Checklist application displays automatically after logging in to the system for the first time after a full installation. The list contains the applications you need to configure your system for general use.

• The ability to perform a cloned installation has been added. A cloned installation lets you duplicate the file system layout, file system type, and software subset selections from a similar type system that has already been installed with Digital UNIX Version 4.0. Installation cloning can only be performed using RIS. If your system is registered to a RIS environment and a configuration description file (CDF), the installation procedure retrieves the CDF and uses the system configuration information stored in the CDF to configure and install your system. Performing a cloned installation alleviates the need to answer most questions during the installation procedure.

• The ability to perform an interactive kernel build has been added to the update installation procedure.

Related Documentation

The printed version of the Digital UNIX documentation set is color coded to help specific audiences quickly find the books that meet their needs. (You can order the printed documentation from Digital.) This color coding is reinforced with the use of an icon on the spines of books. The following list describes this convention:

Audience	Icon	Color Code
General users	G	Blue
System and network administrators	S	Red
Programmers	P	Purple
Device driver writers	D	Orange
Reference page users	R	Green

Some books in the documentation set help meet the needs of several audiences. For example, the information in some system books is also used by programmers. Keep this in mind when searching for information on specific topics.

The Documentation Overview, Glossary, and Master Index provides information on all of the books in the Digital UNIX documentation set.

Read the related documentation in the following order:

1. The documentation for your hardware shows how to set up the processor and its additional devices, and supplies valuable troubleshooting guidelines.

2. Before beginning the installation, read the Digital UNIX Version 4.0 Release Notes.

3. Refer to Sharing Software on a Local Area Network for information about Remote Installation Services (RIS) and Dataless Management Services (DMS). RIS lets you install software products over a network. DMS lets you set up an environment where the root and /usr file systems are exported from a server onto a client.

4. Refer to System Administration for information about administering and maintaining your system. This guide also contains information about the POLYCENTER Advanced File System (AdvFS).

5. Refer to Network Administration for information about network setup and network administration.

6. Refer to Software License Management for information about registering and loading Product Authorization Keys (PAKs), the software licenses from Digital Equipment Corporation.
