Firmware archive for the Afox IB75-MA motherboard; the trailing 2 in the name may indicate a second variant or revision of the board, but this is not certain. The ZIP is 2.45 MB and its contents are not described in the name. Dumps like this are used to recover a board with corrupted BIOS by programming the SPI chip directly with a programmer. Check the model and revision printed on the PCB, back up the existing chip before writing, and confirm the image size matches the flash capacity.
