BIOS image for the ASUS PRIME Q270M-C desktop motherboard, firmware version 1607, supplied as a 15.3 MB RAR archive. The Q270 is an Intel business chipset, and boards of this kind store their UEFI firmware on an SPI flash chip that can be reprogrammed off-board with a programmer when the board is bricked. Back up the original chip before writing, since it holds the board-specific MAC and serial data. Check that the image size fits the installed flash part.
