BIOS file for the ASUS M5A78L-M LX PLUS desktop motherboard, version 1701, in a ZIP of about 867 KB. Such an image can be applied through the ASUS EZ Flash utility on a working board, or written directly to the SPI chip with a programmer when the board no longer posts. Check that the board model printed on the PCB is exactly the LX PLUS variant, since similar M5A78L-M boards use different firmware, and save the original chip contents before writing.
