Firmware dump for an H81H3-M4 motherboard, version 1.0, stored in a 1.16 MB RAR archive. No brand is named, and this board shape appears in several OEM desktops. Such images are written directly to the SPI BIOS chip with an external programmer when a board shows no display or loops after a failed update. Back up the original chip first, and check that the extracted image size equals the flash capacity. Compare the board label and revision before writing, since regional and OEM variants carry different firmware.
