    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 white pads. Have someone a clue what is the interest of these 40 white pads (why are they here) and are they really direct linked to the bios chip.(actually i have seen similar pads on several mobo of laptops but have never understand the utility of this pads).

    The 40 white "pads" aren't pads and aren't white. They should be contacts and metallic. They're usually indicative of a chip that isn't included on this particular motherboard, but may be on a similar motherboard using the same PCB.

    Why this person would want to solder wires to the contacts is beyond me, but I'd be it's some sort of far-fetched overclocking idea (as these things tend to be). Whether or not it'll work is impossible to determine without further information.

    After reading the article of the photo's guy i discovered that he is programming a new bios chip of his mobo by wiring theses "contacts" to an external programmer and it seems to work..
