Working BIOS for a Dell Vostro desktop with the MIH81R motherboard, Wistron board number 13040-1M, compressed as a 3.42 MB RAR. MIH81R points to an Intel H81 chipset board, and the five-digit dash-suffix number follows Wistron's pattern. Unpack it and flash it with an external programmer when the system fails to post. Save the original chip contents first, verify the board number on the PCB, and make sure the image fits the chip capacity.
