You will now create one MBR partition to contain your OpenBSD data
and one MBR partition on which kernels are located which are loaded
by U-Boot. Neither partition will overlap any other partition.
The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
partition will have an id of '${bootparttype}' (${bootfstype}). The boot partition will be
at least 16MB and be the first 'MSDOS' partition on the disk.
