RAR archive labelled U6V, a name that matches the Asus U6V notebook model line, though the archive itself gives no indication of whether it holds a schematic, boardview or BIOS image. At 873 KB it is small enough to be either a compressed firmware dump or a modest PDF. Extract it and inspect the contents before use. If it contains firmware, compare the image size with the SPI chip on the board and save a backup of the original chip with your programmer before writing anything, and always confirm the board number printed on the PCB.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
