BIOS image for the Dell 15 5510 on board 213111-1, packed in an 11.3 MB RAR containing a 32MB dump for a 256 Mbit SPI flash chip. Six-digit numbers with a dash suffix follow the Wistron board scheme, the ODM behind many Dell designs. Use it to repair a laptop with corrupted firmware or one stuck at no display. Match the number printed on the PCB, read the existing chip with a hardware programmer and keep that backup, then flash and verify the image before powering up.
