Acer desktop BIOS for a board labelled MCP61PM-AD, with SN in the name, in a small 532 KB RAR archive. MCP61 refers to an Nvidia nForce chipset generation used on budget AMD desktops. The name gives no model or version, so the image should be identified after extraction. It can be written to the motherboard flash chip with a programmer to recover a board that no longer boots. Verify the board name on the PCB, confirm the chip capacity matches the image, and keep a copy of the original chip contents before flashing.
