ZIP archive of BIOS firmware labelled Y570, 1.58 MB, most likely for a Lenovo IdeaPad Y570, though the name gives no brand, board number or revision. Open the archive to see whether it holds a full SPI dump or an update package, since the compressed size alone does not reveal that. A full image must match the flash chip capacity before writing with a programmer. Save the original chip contents first and verify the board before relying on it.
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 @biosbigarchives. Enginerys does not host this file.
