BIOS dump for a laptop on Quanta board DA0BLXMB6G0 with C55C-14G in the name, which does not name the brand. The 3.12 MB ZIP is marked tested OK, meaning it was reportedly working on a real board. Quanta DA0...MB6 codes end in the revision letter, so compare the full code with your PCB. Before programming the SPI chip, read and save its existing contents, then check that the image size matches the flash capacity.
