Since I'm digging into this now also, let me point out that
the above reference is a bit ... prolix. It does *not* address
the specific issues bsdknowledgeseeker asked about: the place
where the kernel is mapped, initialization of page tables,
etc. For example, here is the entirety of what the above
document has to say about boot2:
boot2 is slightly more sophisticated, and understands
the FreeBSD filesystem enough to find files on it, and
can provide a simple interface to choose the kernel or
loader to run.
Since the loader is much more sophisticated, and
provides a nice easy-to-use boot configuration, boot2
usually runs it, but previously it was tasked to run
the kernel directly.
If there is more detailed documentation somewhere, I'd be happy
to receive a pointer to it. For now, I'm in UTSL mode. If I
survive that, maybe I'll write something up. Was mich nicht
umbringt, macht mich staerker :-).
