BIOS archive for Foxconn 671MX series desktop motherboards, a compact 990 KB RAR file. The name points to the SiS 671MX chipset family. No exact board revision is stated, so compare the model and revision silkscreened on the PCB before use. Older boards of this kind typically use a small SPI or LPC flash chip, so the image size must match the chip capacity. Read and save the original contents with a programmer first, then write and verify, which can recover a board that does not post after a failed update.
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.
