Tested BIOS for a desktop motherboard identified only as H81H3-LM3, supplied in a 4.19 MB RAR archive; no brand is given in the name. The H81 in the model suggests an Intel H81 chipset board, though the name confirms only the model string. Such a dump is written to the SPI flash with a programmer when a board will not boot after a failed update. Read and save the original chip first, confirm the model on the PCB, and verify the image size matches the chip.
