BIOS dump for the Lenovo Y50-70, marked ok to indicate a tested image, supplied as an 8.00 MB raw binary. No board number or revision appears in the name, so check the motherboard markings against the dump before relying on it. Technicians write such files to the SPI flash chip with a hardware programmer when the laptop powers on without display or the BIOS is corrupted. Save the original chip contents first, since serial and activation data may be stored there, and confirm the chip is 8 MB.
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.
