Layout file for the ASUS ET1620I all-in-one motherboard, revision 1.2, with the board identifier 60PT00T0-MB2A02 stated in the name. The 335 KB RAR archive holds the boardview itself, which opens in common viewers such as OpenBoardView, FlexBV or ZXW-type tools. Technicians use it to look up part locations, check which nets join a suspect capacitor, and trace supply rails back to their source. Several ET1620I revisions exist, so match both the 1.2 revision and the 60PT00T0 number against the silkscreen first.
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 @BoardSchematic. Enginerys does not host this file.
