93You will now create a single MBR partition to contain your OpenBSD data. This
94partition must have an id of 'A6'; must *NOT* overlap other partitions; and
95must be marked as the only active partition.  Inside the fdisk command, the
96'manual' command describes all the fdisk commands in detail.

132You will now create an OpenBSD disklabel inside the OpenBSD MBR
133partition. The disklabel defines how OpenBSD splits up the MBR partition
134into OpenBSD partitions in which filesystems and swap space are created.
135You must provide each filesystem's mountpoint in this program.
136
137The offsets used in the disklabel are ABSOLUTE, i.e. relative to the
138start of the disk, NOT the start of the OpenBSD MBR partition.
