Not a 5.25" disk. ProDOS doesn't contain any code to format a 5.25"
disk - you have to write this code yourself (or license it from Apple.
It is a moderately large amount of machine code.
A 3.5" disk is somewhat easier, because the formatting routine is
provided by the interface card and/or drive. This just does the
physical format - it doesn't set up the boot block, volume directory
or bitmap.
If you wanted to make a bootable disk, you would still need the boot
block image, and you have to set up the volume directory and bitmap,
which is not trivial.
