ROM image of the system BIOS for the Dell Inspiron 15 3543, 8 MB in size, which matches a 64 Mbit SPI flash chip. No board number or revision appears in the name, so verify that the motherboard fitted is the one used in the 3543 before writing. Technicians flash such dumps with an external programmer to revive a board with corrupted firmware or a failed update. Save the original chip contents first, because they contain the service tag and other machine-specific data that a generic image may overwrite.
