If you look within the release directory on either the FTP site or the CD-ROM, you'll see the following:
A directory for each architecture OpenBSD supports. (On CD-ROM, this is scattered between different disks.)
A "packages" directory containing precompiled software for this release (see Chapter 13.)
A "ports.tar.gz" file containing the compressed ports tree (see Chapter 13.)
A compressed file containing the source code of the X Window System for this release.
A "tools" directory containing installation tools.
Take a look through your CD-ROM or FTP site, and make sure you can find the directory for your hardware architecture. I'll be using the i386 directory in the rest of this chapter; if you're on a different hardware platform, substitute the correct architecture directory everywhere.
