Good summary.  Thanks for the explanation; I appreciate that a great
deal.  I'm getting more and more interested in finding architectureal
documents--tons for the x86, of course.  But I'll go looking for some
books or net articles before I officially ask for suggestions...  :)
Afterall, I can't expect to get any real help if I'm not willing to do
my homework.

I will note this information and do what I can to verify this before
I attempt any install of the OS.

No prisoner's dilemma here.  Over the long term, symbiosis is more
useful than parasitism.  More fun, too.  Ask any mitochondria.
