So how does it work to be more exact? do you press it then flash or does pressing automatically increase control? I was going to flash it to a 7970 reference to unlock voltage, but I wanted to see what the switch does first. I pressed and got apparently nothing. GPU-Z still shows no BIOS and no voltage control. so I am assuming you press it then flash am I correct? and turn it off to go back to default BIOS?
thx

It has two completely separate BIOSs. You can flash one or both of them. I believe one gives stock frequencies the other an OCed version. When you switch you have to reboot the PC for the new settings to take effect (obviously). You can see which BIOS is which with GPU-Z.
