ZIP archive for a Dell desktop board MIH81R, Wistron number 13040-1M, marked Clear, which usually indicates a cleaned dump with personal data or ME settings reset. MIH81R points to an H81 chipset design, a common Wistron OEM board for Dell systems. Wistron uses this five-digit project numbering. Confirm the board number on the PCB, back up the original flash with a programmer, and check that the image size matches the SPI chip before writing, otherwise the board may fail to POST.
