93You will now create one MBR partition to contain your OpenBSD data
94and one MBR partition on which the OpenBSD boot program is located.
95Neither partition will overlap any other partition.
96
97The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
98partition will have an id of '${bootparttype}' (${bootfstype}).
99The boot partition will be at least 16MB and be the first 'MSDOS'
100partition on the disk.
