No Connection

[Xander Pirdy]

I am not sure, but it kind of sounds like you have networking disabled
in your bios, I just can't imagine how apart from that, and on known
good hardware internet wouldn't work on several live systems that were
previously also known to work. Just a suggestion, not even sure how
many bioses have this option.
