BIOS and EC firmware archive for the Fujitsu Lifebook U772 ultrabook. Including the embedded controller image is helpful when a board has power, charging or keyboard faults caused by corrupted EC code rather than the main BIOS. The name gives no board number or revision, so compare the board markings and image sizes against your chips first. Use an SPI programmer to read and save the original contents before writing either image, and verify each write to confirm the data was programmed correctly.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
