93You will now create one MBR partition to contain your OpenBSD data
94and one MBR partition on which kernels are located which are loaded
95by U-Boot. Neither partition will overlap any other partition.
96
97The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
98partition will have an id of 'C' (MSDOS). The boot partition will be
99at least 16MB and be the first 'MSDOS' partition on the disk.

135You will now create an OpenBSD disklabel inside the OpenBSD MBR
136partition. The disklabel defines how OpenBSD splits up the MBR partition
137into OpenBSD partitions in which filesystems and swap space are created.
138You must provide each filesystem's mountpoint in this program.
139
140The offsets used in the disklabel are ABSOLUTE, i.e. relative to the
141start of the disk, NOT the start of the OpenBSD MBR partition.
