You will now create one MBR partition to contain your OpenBSD data
and one MBR partition to contain the program that PMON uses
to boot OpenBSD. Neither partition will overlap any other partition.
The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
partition will have an id of '83' (Linux files). The boot partition will be
at least 1MB and be the first 'Linux files' partition on the disk.
The installer assumes there is already an ext2 or ext3 filesystem on the
first 'Linux files' partition.

Once the machine has rebooted use PMON to boot into OpenBSD, as

To load the OpenBSD bootloader, use 'boot /dev/fs/ext2@wd0/boot/boot',
where wd0 is the PMON name of the boot disk.
