[LinuxBIOS] New with a GA-M57SLI-S4

[Beth]

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.
