99You will now create one MBR partition to contain your OpenBSD data
100and one MBR partition on which kernels are located which are loaded
101by U-Boot. Neither partition will overlap any other partition.
102
103The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
104partition will have an id of 'C' (MSDOS). The boot partition will be
105at least 32MB and be the first 'MSDOS' partition on the disk.
