hey
any hardware hack that big would make me seriously nervous, the possibility of burning your card or miggy or both is too great.
so whats my solution? sell me the card then you wont have to worry about disabling it. :-D kidding
i got an order from my wife a few years ago so i got rid of my two mint a1000s and bought an a1200
ive been aquiring parts for something more allong the lines of a big box since then.
good luck
