Firmware image set for the Gigabyte GA-H81M-S2PT motherboard at revision 1.1, an Intel H81 micro-ATX board, stored in a 2.86 MB ZIP. A separate package exists for revision 1.0, so check the rev marking printed on the board before choosing. Technicians flash such images onto the SPI BIOS chip with a programmer when the board fails to post after a bad update. Read and keep the original contents beforehand, and make sure the image length matches the flash chip size.
