Yep! Formatting is a lowlevel task not an operating system primitive.
Too many assumptions of disk layout, controller and IO to have a standard
and it's memory space that is better used for other things. The CP/m
solution is a LLF that runs as a transient. That is usually supplied with
the system by it's vendor... however if your running or want to run other
disks, you generally have to write your own.

What's the controller chip on the 4fdc?
