Hi ST, nice to talk to you. Today I don't have time, I must go to work now, but as soon as I can I will try to make the pin to pin test.
If they are directly connected it's true that maybe a software switch make the selection of which bios take the control at start up, I am not a low level man (a bit a bit), but without specifications and as you say with the patents on hand will be hard to find how it is done. Maybe dis assembling the code, but as I say, my low level knowledge is very low :D. As soon as I can i will put my hands on the multimeter or the oscilloscope and do something (the bricking is not on my plans, yet :D). Regards, Jose.
