You could theoretically override the bios with specially designed card
in an old ISA slot, but I don't think it is possible with the PCI or
PCMCIA buses (it depends on the bridge chip set used - I don't think any
would allow that).

That seems to be what your life is all about. Isn't that true dude? Being
beter,knowing more and just out to prove the world is wrong about you..
I'm neither a lier or a no it all .. altough I would perfer the former to
the latter.
