BIOS firmware for the M5A78L-M LX V2 desktop motherboard, an ASUS AMD-platform model name, provided as a 784 KB RAR archive. The name gives no version number, and it does not say whether the file is a factory BIOS or a chip dump. Use it to recover a board that no longer posts by writing the SPI or LPC flash with a programmer. Check that the board silkscreen reads V2, since other revisions exist. Save the current chip contents first, and make sure the image size matches the chip capacity.
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 @biosarchive. Enginerys does not host this file.
