Here is an example of what the partition information will look like once
you have entered the disklabel editor. Disk partition sizes and offsets
are in sector (most likely 512 bytes) units.

Make sure these size/offset pairs are on cylinder boundaries (the number
of sector per cylinder is given in the `sectors/cylinder' entry.

If this disk is previously un-labeled, only the "c" partition will show up
in the editor and you will have to enter lines similar to those shown in the
example for the other paritions.  If you are uncertain about the syntax or
space requirements, this is a good time to review the installation notes.

Do not change any parameters except the partition layout and the label name.
It's probably also wisest not to touch the `16 partitions:' line, even
in case you have defined less than sixteen partitions.

[** EXAMPLE **]
disk: p4200s
bytes/sector: 512
sectors/track: 40
tracks/cylinder: 8
sectors/cylinder: 320
cylinders: 1280
total sectors: 409600

16 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:    51200        0    4.2BSD     1024  8192    16 	# (Cyl.    0 - 159)
  b:    51200    51200      swap                    	# (Cyl.  160 - 319)
  c:   409600        0    unused        0     0       	# (Cyl.    0 - 1279)

This program is designed to help you put OpenBSD on your disk,
in a simple and rational way.  You'll be asked several questions,
and it would probably be useful to have your disk's hardware
manual, the installation notes, and a calculator handy.

This program is designed to help you upgrade your OpenBSD system in a
simple and rational way.

As a reminder, installing the `etc' binary set is NOT recommended.
Once the rest of your system has been upgraded, you should manually
merge any changes to files in the `etc' set into those files which
already exist on your system.

cat << \__welcome_banner_3

As with anything which modifies your disk's contents, this
program can cause SIGNIFICANT data loss, and you are advised
to make sure your data is backed up before beginning the
installation process.

Default answers are displayed in brackets after the questions.
You can hit Control-C at any time to quit, but if you do so at a
prompt, you may have to hit return.  Also, quitting in the middle of
installation may leave your system in an inconsistent state.

OK, then.  Enter `halt' at the prompt to halt the machine.  Once the
machine has halted, power-cycle the system to load new boot code.

To boot the installed system, enter halt at the command prompt. Once the
system has halted, reset the machine and boot from the disk.
