95You will now create one MBR partition to contain your OpenBSD data
96and one MBR partition to contain the program that PMON uses
97to boot OpenBSD. Neither partition will overlap any other partition.
98
99The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
100partition will have an id of '83' (Linux files). The boot partition will be
101at least 1MB and be the first 'Linux files' partition on the disk.
102The installer assumes there is already an ext2 or ext3 filesystem on the
103first 'Linux files' partition.

138Once the machine has rebooted use PMON to boot into OpenBSD, as
139described in the INSTALL.$ARCH document.
140To load the OpenBSD bootloader, use 'boot /dev/fs/ext2@wd0/boot/boot',
141where wd0 is the PMON name of the boot disk.
