Grrrr.... sorry, my ignorance showing here... <:-(

I don't know what the inside of the machine *looks* like
so I end up thinking in terms of the Pea Sea world -- where
PCI conjurs images of expansion cards (though it is also
the basis of on-board interfaces as well).

So, I guess the "PCI flash" is "soldered down" when and
if it is present?  I.e. *not* intended as a "dedicated Flash
portion of the PCI address space which could be
used by an expansion card designed to exploit that
feature"?

Is the "Memory Data Bus" Flash *also* "on board"?
I.e. are there *any* buses that come out to connectors
for "expansion"?
