Boardview for the Gigabyte GA-Z77-D3H desktop motherboard at revision 1.1, packed as a zipped TVW file. Extract it and open it in a TVW-capable viewer to search for components by reference, follow nets and find test points. That helps when chasing a shorted VRM, a missing standby rail or a damaged slot. Gigabyte boards change layout between revisions, so confirm that the PCB silkscreen reads REV 1.1 before using the placement data.
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 @vinafix_bios. Enginerys does not host this file.
