BIOS dump for the Dell Inspiron 15 3520, marked in the name as tested and working, packed in a 10.9 MB RAR archive. No board number or flash chip size is given, so open the archive, check the image size, and compare it with the chip fitted on the motherboard before writing. A dump like this restores a laptop that will not boot after a failed update or corrupted firmware, using a SPI programmer on the flash chip. Read and save the original contents first, because they hold the service tag and system data.
