Lenovo IdeaPad U310 firmware dump in a 2.96 MB 7z archive. The name gives only the model, with no mainboard number, revision, flash chip or version, so check the unpacked file and the board markings before use. The image is used to reprogram the SPI BIOS chip with a programmer such as a CH341A when the ultrabook will not POST or a BIOS update failed. Back up the original chip contents first, and check the image size matches the installed flash part.
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 @biosfiles. Enginerys does not host this file.
