BIOS dump for the Lenovo IdeaPad U310, read from a Winbond W25Q64 SPI flash chip, which corresponds to 8 MB. The name also carries the numbers 2014218 and 94127, whose meaning it does not explain. The matched board is Quanta DA0LZ7MB8E0, following the Quanta DA0-style numbering used on its motherboards. The RAR archive is about 2.98 MB. Extract the image and write it with an SPI programmer after backing up the current chip contents. Confirm that the board number on the PCB matches and that the image size equals the chip capacity.
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.
