ZIP archive of about 3.1 MB with BIOS firmware for the Lenovo IdeaPad Z510. The name lists no board number, version or contents, so open the archive and check whether it holds a raw chip dump or a vendor update package. Raw images are written to the SPI flash with an external programmer and must match the chip capacity exactly. Compare the motherboard number printed on the PCB with the source, and back up the original chip 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 @biosarchive. Enginerys does not host this file.
