Firmware dump for the Dell Vostro 15 3546 in its Celeron configuration, using the Janus board numbered 13302-1. Boards with this five-digit dash numbering and a code name come from Wistron, the ODM behind many Dell machines. The 9.20 MB RAR archive is the usual source when a technician reprograms a corrupted SPI BIOS chip after a failed update or a no-boot fault. Compare the board number on the PCB before flashing, keep a backup of the existing chip, and make sure the file size fits the flash part.
