BIOS firmware shared by the Dell Inspiron 5521 and 3521 notebooks, marked for Core i7 boards, with PM probably referring to the board variant or a power-management build, which the name does not explain. It comes as a 3.12 MB RAR, so inspect its contents and image size before flashing. Dell dumps include the service tag and other system data, so save the original SPI read first. Typical use is reflashing the BIOS chip on a board that powers up without display. Confirm the board number on the PCB.
