Firmware archive for a Shinelon laptop listed as A-394HN7, built on the Quanta-numbered board DALG9CMB6E0 revision E. The DA...MB...0 pattern is Quanta's board code, and the letter after REV identifies the PCB revision. Technicians use such a dump to recover a board with corrupted BIOS by writing the SPI flash directly with a programmer. Read and keep the existing contents first, and make sure the silkscreen revision and the flash capacity match the image before writing.
