Motherboard BIOS ROM packed in a ZIP of 2.97 MB, labelled H81 Pro BTC revision 2.0 with firmware version 1.20. The H81 token points to the Intel H81 chipset, and BTC suggests a mining-oriented desktop board, though the name does not state the vendor. Technicians use such a ROM to recover a board with a corrupted BIOS by writing the SPI flash chip on a programmer. Check the board revision printed on the PCB, keep a backup of the existing chip, and make sure the file size matches the flash capacity.
