thanks
i try to tell you if i can switch the component on another same board, i have my answer is yes....
sorry i'm not english, i try to speak in your language but it's not easy.

The BIOS ME region pairs itself with the PCH chip. If you put another BIOS on it will be paired to the PCH of the other board and not work properly. It will turn on, but you will get random shit like running slow, integrated graphics not working right, wifi sometimes not working. Just buy a programmer to do this properly.
