Working BIOS dump for the Lenovo ThinkPad T500, described as fully functional, packed in a 3.09 MB RAR archive. The name gives no BIOS version, board number or chip size, so extract the image and compare its size with the SPI flash on the motherboard before programming. A dump like this restores laptops that are dead after a failed update or show no display at power-on. Read and save the existing chip first, because machine-specific data such as serial number and UUID live in the same flash region.
