BIOS for the ASUS M4N78 SE desktop motherboard, sized for a 1 MB flash chip according to the name, delivered as a RAR archive. A desktop board BIOS like this is used to recover a failed update or a corrupted chip, either through a programmer on a removable or soldered SPI chip or through the board's own flashing utility. The archive is larger than 1 MB, so it may hold more than one file. Make sure the image you pick is exactly 1 MB and save the original chip contents first.</parameter>
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.
