This is an interface to the builtin and external floppy drives on the Atari. Currently, there is no disklabel support for the floppy drives. Instead, the floppy interface uses the partition number embedded in the minor device number to distinguish between various floppy formats.

Currently, the following formats are supported:

Partition Size sides tracks sectors/track
a 360Kb 1 80 9
b 720Kb 2 80 9
c 1.44Mb 2 80 18

/dev/fd[01][abc]
Block files
/dev/rfd[01][abc]
