BIOS dump for board 15341-1 with the 91N85 code, marked in the name as original and OK, for a version without a discrete GPU. The 5-digit number with a dash suffix follows the Wistron scheme, and no laptop brand is stated. The RAR archive is intended for reprogramming the SPI flash with an external programmer. Make sure your board is also the integrated-graphics variant, save the existing chip contents first, and check that the image size matches the flash capacity.
