Guide to Unix/BSD/OpenBSD/OpenBSD Installation

OpenBSD has an easy (although non-graphical) installation procedure.

Starting Installation
erase ^?, werase ^W, kill ^U, intr ^C, status ^T (I)nstall, (U)pgrade or (S)hell? i Welcome to the OpenBSD/i386 4.4 install program. This program will help you install OpenBSD. At any prompt except password prompts you can escape to a shell by typing '!'. Default answers are shown in []'s and are selected by pressing RETURN. At any time you can exit this program by pressing Control-C, but exiting during an install can leave your system in an inconsistent state. Terminal type: [vt220]   kbd(8) mapping? ('L' for list) [none]   IS YOUR DATA BACKED UP? As with anything that modifies disk contents, this program can cause SIGNIFICANT data loss. It is often helpful to have the installation notes handy. For complex disk configurations, relevant disk hardware manuals and a calculator are useful. Proceed with install? [no] yes Cool! Let's get to it. You will now initialize the disk(s) that OpenBSD will use. To enable all available security features you should configure the disk(s) to allow the creation of separate filesystems for /, /tmp, /var, /usr, and /home. Available disks are: wd0. Which one is the root disk? (or done) [wd0]   Do you want to use *all* of wd0 for OpenBSD? [no] yes Putting all of wd0 into an active OpenBSD MBR partion (type 'A6')...done. You will now create an OpenBSD disklabel inside the OpenBSD MBR partition. The disklabel defines how OpenBSD splits up the MBR partition into OpenBSD partitions in which filesystems and swap space are created. The offsets used in the disklabel are ABSOLUTE, i.e. relative to the start of the disk, NOT the start of the OpenBSD MBR partition. Treating sectors 63-80292870 as the OpenBSD portion of the disk. You can use the 'b' command to change this.
