Fully working BIOS image for the Dell Inspiron 15-3543 using the Intel Cedar mainboard, Wistron board 13269-1. Wistron, Dell's ODM for this platform, numbers its boards with a five-digit project code and suffix such as 13269-1. Technicians flash this kind of dump onto the SPI chip with an external programmer to revive dead boards or repair a corrupted firmware region. Make sure the PCB carries the same 13269-1 marking, read and store the original chip contents first, and check the image fits the chip size.
