Where is the 'dual bios switch' located? Is this a 'virtual' switch in SW, or is it something I can see physically? If it's hardware (not SW) - can I see it with the card plugged in, or do I have to power down and remove the card (like I would need to do to check for AMD logo on pin connector)?
I've got 3 x 6950s (2GB HIS) that are hoping to be unlocked (shaders only - I don't want to risk the 6970 flash).
the switch is real IF you have it, pretty easy to spot beside crossfire connector, if you cant see it/find you dont have one
