|
|
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.
|
|

|
|
.Bl -column Partition Size sides tracks sectors/track
