BIOS package for the Afox IH81-MA5 desktop motherboard, a 2.80 MB ZIP archive. The name suggests an Intel H81 based board, though nothing beyond the model is stated. A firmware image like this is usually written to the SPI flash chip with a CH341A or similar programmer when the board fails to post after a bad update or chip corruption. Read and keep the original contents first, compare the extracted image size with the capacity of the chip fitted, and confirm the board model printed on the PCB.
