Working BIOS dump for the Fujitsu Lifebook U937, labelled fully working. The name gives no motherboard number or revision, so compare the board inside your unit before using it. A firmware image like this is written to the SPI flash with a programmer when the laptop shows no picture or fails to start after a bad update. Read and save the existing chip contents first, because they may hold unit-specific data. Confirm that the image size matches the chip on the board before flashing.
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.
