You will now create a single MBR partition to contain your OpenBSD data. This
partition must have an id of 'A6'; must *NOT* overlap other partitions; and
must be marked as the only active partition.

The 'manual' command describes all the fdisk commands in detail.

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

something like 'boot hd:3,ofwboot /bsd'.
