70You will now create a single MBR partition to contain your OpenBSD data. This
71partition must have an id of 'A6'; must *NOT* overlap other partitions; and
72must be marked as the only active partition.  Inside the fdisk command, the
73'manual' command describes all the fdisk commands in detail.

109You will now create an OpenBSD disklabel inside the OpenBSD MBR
110partition. The disklabel defines how OpenBSD splits up the MBR partition
111into OpenBSD partitions in which filesystems and swap space are created.
112You must provide each filesystem's mountpoint in this program.
113
114The offsets used in the disklabel are ABSOLUTE, i.e. relative to the
115start of the disk, NOT the start of the OpenBSD MBR partition.
