RAR archive of BIOS firmware for the Toshiba Satellite S55-B5289, 7.42 MB compressed. The name does not state the board number, chip size or whether the ME region is cleaned, so inspect the extracted image before use. A dump like this is typically written to the SPI flash with a programmer such as a CH341A to recover a corrupted BIOS. Read and save the original chip contents first. Also confirm that the image size equals the flash capacity, because an image that does not match will not fit.
