There is currently no boot0 documentation.  However, there are a few
obscure configuration options, etc., so something is probably required.

For boot1/boot2, most of the present boot(8) man page applies, though
some information needs to be updated, and additional capabilities
documented.  Someone has also submitted a boot.config(8) man page
(PR 8610), though this hasn't been committed.

For the boot loader, there is some brief online-style documentation in
src/sys/boot/common/help.common and src/sys/boot/i386/loader/help.i386.
This will most likely be considerably expanded as the loader assumes
its final form.

I hadn't really thought about this, but given Windows' predilection for
silently "taking out" the master boot record, I guess this does need
doing.

Unfortunately maintaining DOS programs that support FreeBSD tends
to be a major headache; but it may be possible to cross-compile
something using bcc (Bruce Evans' 16-bit C compiler in the ports
collection).
