I don't know how it's *done*, but I can tell you the principle:  There's
a file called /etc/boot.default which is read by the boot loader, and can
do things like
	-rootdev foo(x,y)
	-dev foo0 port=xxx
(port -1 says "don't probe")

and you can set various other flags.  It also has meta-commands, like
"echo", or "include".

Then, to make things more complete, if you interrupt the boot sequence,
the prompt you get is really just doing the same things as boot.default.

It's a good feature.
