Boardview archive for the ASUS C468PI mainboard at revision 1.00, 294 KB in RAR form. The name states only the model code and revision, with no ODM board number. A layout file like this lets a technician search by reference designator or net name, inspect both sides of the board and find test points for power rails and signal lines. Extract it and load it in a boardview application such as OpenBoardView, then confirm the revision on the PCB is 1.00 before using it for diagnosis.
