Desktop BIOS dump for a board labelled MCP61M-M3, a name that refers to the NVIDIA MCP61 chipset used on budget AMD motherboards; the board maker is not given. The archive is a small 462 KB RAR, consistent with the 512 KB class flash chips of that period. Use it to rewrite a corrupted BIOS chip with an external programmer. Confirm the model and revision silkscreened on the PCB, keep a backup of the original chip, and make sure the image size fits the chip exactly.
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.
