BIOS firmware for the Dell Latitude E5420 business notebook, packed in a 2.33 MB ZIP. No motherboard number, revision or region details appear in the name. Technicians use such a dump to reprogram the SPI flash with an external programmer when the machine is bricked after a failed update or shows no video. Latitude boards may use more than one flash chip, so check which image goes to which chip, back up the originals, and make sure each file size matches the capacity of its chip.
