Raw 4MB BIOS binary for the ESONIC G41CDL3 desktop motherboard, an Intel G41 chipset board according to its model name. A .bin image of this size is normally written directly to the SPI flash with a hardware programmer such as CH341A, TL866 or RT809, which helps recover boards that are stuck on a black screen after a failed update.
