I think it is just an extra in case you mess it up trying to flash one of them. Also I think on some AMD gpu's, the 2nd BIOS is overclocked a little, dont quote me on that though.

One position is a read-only stock bios. You can flip to this in case something goes wrong when trying to flash.

Second position is read-write bios. By default from most vendors is the exact same as the first bios. The only difference is that you are able to overwrite this bios with whatever you want.

Why flash your 6970 bios? IDK... Maybe to a different vendor bios with higher factory overclock?

i was just curious i read on some reviews on some of the 6970's when you flip the switch they were able to get higher clock speeds than on the default factory BIOS just wanted to see if anyone had tried it and if they got higher clock speeds as a result
