BIOS and EC firmware set for the Quanta-made motherboard DA0V02MB6G0, revision G, stored in a RAR archive; the name does not say which laptop model uses it. On Quanta boards the embedded controller often has its own firmware alongside the system BIOS chip, and both may need reprogramming to cure dead or looping boards. Flash with an SPI programmer, back up the existing chip contents first, and make sure each image size matches the target flash chip before writing.
