What's New

This is a partial list of new features and systems included in OpenBSD 4.0. For a comprehensive list, see the changelog leading to 4.0.

How to install

Following this are the instructions which you would have on a piece of paper if you had purchased a CDROM set instead of doing an alternate form of install. The instructions for doing an FTP (or other style of) install are very similar; the CDROM instructions are left intact so that you can see how much easier it would have been if you had purchased a CDROM instead.

Please refer to the following files on the three CDROMs or FTP mirror for extensive details on how to install OpenBSD 4.0 on your machine:

Quick installer information for people familiar with OpenBSD, and the use of the "disklabel -E" command. If you are at all confused when installing OpenBSD, read the relevant INSTALL.* file as listed above!


















Notes about the source code:

How to upgrade

If you already have an OpenBSD 3.9 system, and do not want to reinstall, upgrade instructions and advice can be found in the Upgrade Guide.

Ports Tree

A ports tree archive is also provided. To extract:

The ports/ subdirectory is a checkout of the OpenBSD ports tree. Go read the ports page if you know nothing about ports at this point. This text is not a manual of how to use ports. Rather, it is a set of notes meant to kickstart the user on the OpenBSD ports system.

The ports/ directory represents a CVS (see the manpage for cvs(1) if you aren't familiar with CVS) checkout of our ports. As with our complete source tree, our ports tree is available via anoncvs. So, in order to keep current with it, you must make the ports/ tree available on a read-write medium and update the tree with a command like:

[Of course, you must replace the local directory and server name here with the location of your ports collection and a nearby anoncvs server.]

Note that most ports are available as packages through FTP. Updated packages for the 4.0 release will be made available if problems arise.

If you're interested in seeing a port added, would like to help out, or just would like to know more, the mailing list is a good place to know.
