BIOS firmware for an LH-530 device built on motherboard DA0FH1MB6D0, compressed into a 564 KB RAR. The DA0 prefix and MB6 marking follow the Quanta numbering pattern, where FH1 is the project code and the final characters indicate the board version. Quanta-made boards are used by several brands, so the PCB marking is the reliable reference. The image is used to rewrite a corrupted flash chip with a programmer; back up the original first, confirm the board number and revision, and verify the image size.
