An OpenBSD partition should have type (i.d.) of 166 (A6), and should be the
only partition marked as active. Also make sure that the size of the partition
to be used by OpenBSD is correct, otherwise OpenBSD disklabel installation
will fail. Furthermore, the partitions must NOT overlap each others.
The fdisk utility will be started update mode (interactive.)
You will be able to add / modify this information as needed.
If you make a mistake, simply exit fdisk without storing the new
information, and you will be allowed to start over.

Disk partition sizes and offsets are in sector (most likely 512 bytes) units.
You may set these size/offset pairs on cylinder boundaries
(the number of sector per cylinder is given in )
(the `sectors/cylinder' entry, which is not shown here)
Also, you *must* make sure that the 'i' partition points at the MSDOS
partition that will be used for booting. The 'c' partition shall start
at offset 0 and include the entire disk. This is most likely correct when
you see the default label in the editor.
Do not change any parameters except the partition layout and the label name.
[Here is an example of what the partition information may look like.]
10 partitions:
# size offset fstype [fsize bsize cpg]
a: 120832 10240 4.2BSD 1024 8192 16 # (Cyl. 11*- 142*)
b: 131072 131072 swap # (Cyl. 142*- 284*)
c: 6265200 0 unused 1024 8192 # (Cyl. 0 - 6809)
e: 781250 262144 4.2BSD 1024 8192 16 # (Cyl. 284*- 1134*)
f: 1205000 1043394 4.2BSD 1024 8192 16 # (Cyl. 1134*- 2443*)
g: 2008403 2248394 4.2BSD 1024 8192 16 # (Cyl. 2443*- 4626*)

This program is designed to help you upgrade your OpenBSD system in a

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.

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.
