BIOS package for the Lenovo Ideapad U310 main board DA0LZ7MB8E0, revision E. Numbers beginning with DA0 and ending in MB8xx follow the Quanta scheme, with the trailing letter indicating the board revision. The 2.91 MB RAR contains a dump for restoring the SPI flash with a programmer when the ultrabook has no power-on, no display or a corrupted BIOS. Compare the silkscreen number and Rev E with your board, keep a backup of the original chip, and ensure the image size matches the flash capacity.
