BIOS image for a Dell Inspiron 15 3000 series notebook, tagged FX3MC, which is probably a Dell part number for the motherboard. The file is 8 MB, the size of a 64 Mbit SPI flash chip. Since the 15 3000 name covers many different boards, compare the part number printed on the label or the PCB with FX3MC before using the dump. Back up the original chip, then write and verify the image with a hardware programmer.
