BIOS package for the Dell Inspiron 14-7447 on Quanta board DA0AM7MB8D0, project AM7, PCB revision D, marked as fully working. Quanta numbers its boards with a DA0 prefix printed on the PCB, and Dell sourced this model from that ODM. At 7.13 MB the archive differs in size from another package for the same board, so compare contents. Save the original SPI contents with a programmer before flashing, and check the revision and the chip capacity against the image size.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
