Firmware package for a B450M GAMING motherboard, revision 1.x, delivered as a 10.7 MB zip archive. The name does not state the manufacturer, so match the model and revision printed on the PCB before use. B450 is an AMD chipset for AM4 processors. A package this size may be a vendor update file rather than a raw chip dump, so inspect the contents first. For SPI programming, back up the original chip and verify the image size equals the flash 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.
