When building a floppy for booting in previous versions of Linux (I
suspect this still holds) you take the zImage and copy it to /dev/fd0 and
DON'T create a filesystem on the floppy. It's treated as a character
device, containing just the kernel.
Prior to installing 4.0, I did all my kernel builds, then copied to a
floppy, booted, and tested, THEN copied the kernel for hard disk booting.
I don't know if I can get away with this tactic with 4.0 given all the
modules stuff (not that I've gotten that working yet anyway).
