ZIP archive containing BIOS version 1.80 for the ASRock Z77 Extreme4-M desktop motherboard, an Intel Z77 platform. At 4.18 MB compressed it is most likely the vendor update package rather than a raw programmer dump, so check the contents after extracting. Vendor images can usually be applied with the board's built-in flash utility, while a programmer needs a full-size image matching the chip. Make sure the model on the board is exactly Z77 Extreme4-M before flashing.
