Compressed BIOS image for the Dell Latitude 3420 with board number 213105-1, a numeric style tied to Wistron-built Dell boards. At 11.7 MB packed it likely contains a full SPI flash dump for the main chip. It is useful when a board has a corrupted BIOS, boot loops or no display after a failed update. Identify the flash chip and its capacity, check that the image size matches, read and save the original contents, then write it with an SPI programmer.
