BIOS firmware for a Foxin board labelled FMBG31, supplied as a 459 KB RAR archive. The G31 part of the name suggests an Intel G31 chipset desktop board, though the name gives no further details on revision or chip type. A small image like this suits a low-capacity SPI flash often found on budget motherboards. Use a programmer to read the existing chip first, compare its size with the image inside, and only write after confirming the board marking matches FMBG31.
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 @laptopdesktopbiosbin. Enginerys does not host this file.
