OpenBSDInstallPrelude
Booting the installation media:
The easiest way to boot into the OpenBSD installer is to copy the bsd.rd
installation kernel to the main Linux partition, and boot from it.
Assuming the installation kernel has been copied to /boot/bsd.rd on the
Linux system, at the PMON prompt, enter:
PMON> boot /dev/fs/ext2@wd0/boot/bsd.rd
to boot the installation kernel.
Alternatively, if your particular PMON flavour supports `fat' filesystems,
you can boot the kernel from an usb key with:
dnl check syntax
PMON> boot /dev/fs/msdos@usb0:/bsd.rd
Netbooting the installation kernel can be done as well:
PMON> ifaddr rtl0 <your ip>
PMON> boot tftp://<server ip>/bsd.rd

The fdisk(8) utility will be invoked to let you edit your MBR
partitioning. The current MBR partitions defined will be
displayed and you will be allowed to modify them, and add new
partitions.
After your OpenBSD MBR partition has been setup, the real
partition setup can follow.

OpenBSDInstallWrapup
As the OpenBSD/MACHINE port is very new, there is not yet a proper
bootloader. In addition to these steps, you will need, for the time
being, to copy the kernel image to the Linux partition and boot
from it. This annoyance is being worked on and should disappear
very soon.
After the installation is complete, you should add an OpenBSD
entry to the boot menu to be able to boot OpenBSD more easily.
The boot menu contents are found in /boot/boot.cfg on the Linux
partition. To add an OpenBSD entry, simply add a new entry in the
file, such as:
title OpenBSD
kernel /dev/fs/ext2@wd0/boot/bsd
args ""
In the example above, /dev/fs/ext2@wd0/boot/bsd is the PMON path
to the kernel image.
You may make OpenBSD the default option by changing the ``default''
line near the top of the file. The value on this line is the index
of the default entry, starting at zero. So if you added the OpenBSD
entry as the fourth entry in the file, it would become the default
choice with:
default 3
The timeout until the default choice is selected, in seconds, can be
modified on the ``timeout'' line.
Note that using the boot menu currently disables root device
discovery and kernel symbol loading. Therefore it may be
more convenient to switch to the PMON prompt using 'c' and
boot with the command
PMON> boot -k $bsd
after having set the bsd variable to your boot path
PMON> set bsd /dev/fs/ext2@wd0/boot/bsd
