BIOS image for a Dell 3550 laptop fitted with an Intel Core i7 processor, on Wistron board 10245-1, marked as working. Wistron uses the five-digit number with dash suffix seen here, and the same board number appears on other Dell models. Flash the dump to the SPI chip with a programmer after saving the original contents, especially the service tag and system data. Check that the image size matches the flash chip and that the PCB number is exactly 10245-1.
