Tested BIOS image for the Quanta G3MA laptop motherboard, board number DAG3MMB3AA0 revision A, sized for a 16MB flash chip. Quanta, a contract manufacturer for several brands, prints this DA-style code on the PCB, and the letter after the main code denotes the revision. The RAR carries a dump reported as working, suited to reprogramming the SPI chip with a CH341A or similar tool. Read the original chip first, keep that backup safe, and check that both the board code and the 16MB capacity agree.
