BIOS image for the Fujitsu Lifebook AH531, a 1.98 MB ZIP archive with no board number, revision or firmware version in the name. Check the motherboard part number printed on the PCB against other sources before trusting the dump. A file like this is written to the SPI flash with a CH341A or similar programmer to recover a laptop that powers on with a black screen or stopped booting after an update. Read and store the original chip first, and confirm that the image size equals the flash chip capacity.
