16 MB BIOS binary for an X1403ZA board, revision R3.1, labelled as fully working with display confirmed. A display-confirmed dump is useful when a laptop powers on but shows no image after a failed update or corrupted firmware. The size corresponds to a 128 Mbit SPI chip, so a different-capacity chip will not accept it. Before flashing, read and save the existing contents, as they may hold serial and licence data, then write and verify. Make sure the PCB revision matches R3.1.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
