Flashing 6950 BIOS

[SMOKEU]

I edited a BIOS using RBE but I can't figure out how to flash my card. I tried using WinFlash but I just get the "SubsytemIDs mismatch" error message, and ATI Flash doesn't work because I get a message saying that it's not compatible with my OS (Windows 7 Pro x64). All I really want to do is unlock the shaders and increase the overclocking limit because I think the 6970 BIOS I have on it at the moment is leading to a few stability issues.

You might, I am not sure, but you might need to give it a few cmds in dos to be able to unlock the card to flash it.

I've flashed this card before with Winflash but I just want a simple way of flashing it to shader unlocked 6950 BIOS!
