Boardview for the ASUS P8Z77-V DP desktop motherboard, version 1.00, in the FZ format that ASUS boardviews commonly use. FZ files open in OpenBoardView, FlexBV and similar viewers, giving part locations, pin nets and both PCB sides for quick searching. A Z77 board like this is typically diagnosed by tracing VCore, VCCSA, DRAM and standby rails and locating shorted capacitors. At only 162 KB it is the layout alone, so pair it with a schematic, and confirm the 1.00 revision matches the silkscreen on your board.
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.
