Whilst this is a good idea, it wasn't quite what i was thinking about, for
the only reason ... wouldn't this give us flashing problems, or can you
also arrange to be able to flash to the '2nd' BIOS ..? (I said I was not
much good with digital electronics design ;-))

However, assuming that one BIOS can be programmed, and the other maybe
read-only? any design ideas/plans etc...  If this works, I'd like to get my
hands on a plan ASAP cause this would be just what I need...

If you're carful you could even make a business plan & money from it... but
more on that when we see what we've got....
