Have found somewhere in the net the attached photo of a laptop motherboard. As you notice the author says that "he wants to solder wires between the bios chip (a 40 pin tsop) and these 40 metallic contacts. Have someone a clue what is the interest of these 40 metallic contacts (why are they here) and are they really direct linked to the bios chip.(actually i have seen similar free contacts on several mobo of laptops near the bios chip but have never understand the utility of these pads).
Thanks.
