BIOS and EC firmware for the Dell Vostro 3450 on Quanta board DA0V02MB6E1, revision E, marked as fully working. The 3.29 MB RAR archive should contain both the main BIOS image and the embedded controller firmware. Quanta's DA0 numbering identifies its laptop mainboards, which it makes for Dell. Extract the files and check each image size against its flash chip. Read and save the original contents with an SPI programmer before writing, and confirm the PCB shows DA0V02MB6E1 Rev E.
