87You will now create one MBR partition to contain your OpenBSD data
88and one MBR partition on which kernels are located which are loaded
89by U-Boot. Neither partition will overlap any other partition.

91The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
92partition will have an id of 'C' (MSDOS). The boot partition will be
93at least 32MB and be the first 'MSDOS' partition on the disk.
