92You will now create one MBR partition to contain your OpenBSD data
93and one MBR partition on which kernels are located which are loaded
94by U-Boot. Neither partition will overlap any other partition.
95
96The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
97partition will have an id of 'C' (MSDOS). The boot partition will be
98at least 32MB and be the first 'MSDOS' partition on the disk.
