For GPT entries, there is no distinction between FAT and NTFS partitions. Both have partition type EBD0A0A2-B9E5-4433-87C0-68B6B72699C7.

If the non-FAT partitions do not get a drive letter assigned at boot, there is no way to reformat a such partition under FreeDOS with a FAT filesystem, at least with the format utility currently provided by FreeDOS.

Perhaps this behaviour should be configurable?
