bool rtems_bdpart_format::dos_compatibility

This option is used for partition table creation and validation checks before a write to the disk.

It ensures that the first primary partition and the logical partitions start at head one and sector one under the virtual one head and 63 sectors geometry. Each begin and end of a partition will be aligned to the virtual cylinder boundary.
