BIOS dump for a Dell machine on Wistron board 15341-1, noted in the name as a 7th generation platform, which most likely refers to the Intel Core processor generation, and marked as tested. No model name is given, so identify the system by the board number printed on the PCB. The 7.53 MB RAR archive is used to restore firmware through an external SPI programmer. Wistron boards carry a five-digit number with a revision suffix. Save the original chip contents first and check that the image size fits the flash chip.
