Dear all, pls refer to this diagram:
http://ps2modchip.com/Messiah%202%20...0&%2035000.jpg

On this diagram, the two pics on lower left corner show the locations of "almost the same pts. These are alternative pts? However, I see only one of them has "Z" pt shown. We should solder it anyway, right?

BTW, why this Z pt on the back side of the mainboard? Anyone know why? Thanks!
