92You will now create one MBR partition to contain your OpenBSD data
93and one MBR partition on which the OpenBSD boot program is located.
94Neither 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 '${bootparttype}' (${bootfstype}).
98The boot partition will be at least 16MB and be the first 'MSDOS'
99partition on the disk.
