There's still a "helper" script (`/usr/mdec/binstall') that might be
inspected (or even run, but there's no guarantee on foreign tftp hosts)
for guide-lines.

It currently has:

	cp /usr/mdec/boot tempfile
	printf '\01\03\01\07\060\200\0\07' | dd of=$TARGET bs=32 conv=sync
	dd if=tempfile of=$TARGET bs=32 skip=1 seek=1

which should produce an image that is acceptable to both sun4 and sun4[cm]
ROMs.  (See installboot.c for an explanation of the numbers..)
