Recommendation for unlockable 6950?

[Cluster2k]

I have a Powercolor 1Gb 6950.  It has a BIOS switch but refused to be unlocked.  Didn't pursue the matter further.  I also have HIS 1Gb 6950s without BIOS switches so I didn't try on those.

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)?

Thanks.

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
