BIOS archive for the ASUS M5A78L-M LX micro-ATX board, the original revision without the V2 suffix, intended for AMD socket AM3+ processors. At about 1.6 MB the archive may hold more than one image or a vendor update with tools. Inspect the contents before flashing and pick the image that matches the flash chip capacity. Confirm that the board is not the V2 or LE version, which have their own firmware, and save a dump of the current chip so the change can be reversed.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @Laptopdesktopbios. Enginerys does not host this file.
