88You will now create one MBR partition to contain your OpenBSD data
89and one MBR partition on which the OpenBSD boot program is located.
90Neither partition will overlap any other partition.

92The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
93partition will have an id of '${bootparttype}' (${bootfstype}).
94The boot partition will be at least 16MB and be the first 'MSDOS'
95partition on the disk.
