the rescue floppy has only one purpose on powerpc, and that is to
provide the kernel image that is installed in the `install OS and
kernel modules' step.  the bootable rescue floppy for oldworld macs is
the hfs-boot.img (or whatever its called).

there is one, boot-hfs.img, except its broken in current boot
floppies...  there is no boot floppy for newworlds since no newworld
has a floppy drive.

that is exactly how x86 rescue floppies work.

unless someone figures out how to fix the oldworld boot floppies im
not sure there is a point in documenting them :(

yup, newworlds actually have a implementation of OF that works (for
the most part).
