Firmware dump for the Dell Studio 1555 built on the Quanta FM8 motherboard, board number DA0FM8MB8E0 at revision E. Quanta encodes the project code in DA0 numbers, here FM8, and the revision letter matters because component changes between revisions can affect firmware compatibility. Compare the silkscreen on your PCB with the board number before programming. Read and keep a backup of the existing SPI chip with your programmer, then check that the extracted image size matches the chip capacity, since an image that does not match the chip will not fit.
