Firmware dump for a laptop mainboard numbered DA0R23MB6D0, revision D, marked as tested and working. The DA0...MB6D0 pattern is Quanta's board numbering, where the middle letters identify the project and the final characters reflect the revision. The 1.36 MB RAR should hold a SPI flash image for reprogramming the BIOS chip with an external programmer. Before writing, check that the PCB silkscreen shows the same number and revision, back up the existing chip, and make sure the file size equals the chip capacity.
