72You will now create one MBR partition to contain your OpenBSD data
73and one MBR partition on which kernels are located which are loaded
74by U-Boot. Neither partition will overlap any other partition.

76The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
77partition will have an id of 'C' (MSDOS). The boot partition will be
78at least 32MB and be the first 'MSDOS' partition on the disk.
