BIOS archive named DG41KR, which matches an Intel desktop board model code built on the G41 chipset. No version or chip size is given beyond the 869 KB RAR size. Intel boards of this generation store firmware on an SPI chip that can be rewritten with a programmer when the board is bricked. Read and keep the original contents before writing. Verify the model printed on the board and that the image size matches the flash chip.
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.
