Boardview covering the ASUS P8H77-M PRO DP variant at revision 1.01, compressed into a RAR file of about 113 KB. Opening it in a tool such as OpenBoardView, FlexBV or a similar viewer shows the physical placement of every part together with its nets, which helps when locating MOSFETs, chokes and test pads or when checking where a short to ground leads. Note that the DP variant is listed separately from the standard P8H77-M PRO, so compare the model name and revision silkscreened on the PCB before using it.
