BIOS image for the ASUS M5A78L-M-USB3, a micro-ATX desktop motherboard for AMD processors, in a small 795 KB rar. The name gives no version number, so look at the file inside to identify it. A technician typically writes such an image to the socketed or soldered SPI chip with a programmer when the board fails to POST after a bad update. Read and keep the original chip contents first, and make sure the image size matches the flash capacity, otherwise the write will fail or the board will not start.
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.
