Firmware package for the I-G31 motherboard: a 392 KB ZIP containing its BIOS image. No version string or revision is included in the name, so verify the build from the extracted file or an accompanying text. A known-good image is the standard fix for boards that died during an update or lost settings due to chip corruption. Program it with a hardware programmer after backing up the existing contents, or with the onboard flash tool if the board still starts. Confirm the model on the PCB and that file size matches the 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.
