BIOS image read from a Gigabyte H310M S2 motherboard, revision 2.0, stored in a 6.09 MB RAR archive. A read dump like this is taken straight from the SPI flash chip with a programmer, so it can restore a board whose firmware is corrupted or failed after a bad update. Before writing it, save a copy of your own chip contents, confirm the image size matches the flash capacity, and check the board model and revision label, since H310M variants use different firmware.
