Archive tied to the Acer Aspire V3-574 laptop, packed as a 3.87 MB zip. Beyond the model name the file title states nothing about its contents, board number or revision, so treat it as unidentified repair material until extracted. It may contain a schematic, a boardview or a flash dump. Once unpacked, check which ODM board it describes and confirm that number against the one printed on your mainboard. If it turns out to be a BIOS image, back up the original SPI chip with a programmer before writing anything.
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 @laptopbios21. Enginerys does not host this file.
