Archive of 226 KB for the P7H55-M LE, an entry-level H55 chipset desktop motherboard model in the ASUS style of naming. The name does not state what kind of file is inside, so extract it to determine whether it is a boardview, a schematic or something else. When it is a board file, a viewer such as FlexBV or OpenBoardView lets you highlight nets and find test points around the CPU VRM and chipset. Confirm the LE variant and revision printed on the board match before working from it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
