Firmware dump for the Biostar A58MDP motherboard at version 8.0, described as working and stored in a RAR archive of around 2.1 MB; the brand field shows ECS. Having a second known version is handy when one release refuses to boot on a particular board. Extract the image and flash it to the SPI BIOS chip with a hardware programmer, after backing up the original contents. Check that the chip capacity matches the image length and that the board is truly the A58MDP, as similar Biostar models use different firmware.
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.
