98You will now create one MBR partition to contain your OpenBSD data
99and one MBR partition on which kernels are located which are loaded
100by U-Boot. Neither partition will overlap any other partition.

102The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
103partition will have an id of 'C' (MSDOS). The boot partition will be
104at least 32MB and be the first 'MSDOS' partition on the disk.
