Firmware dump for the Dell Inspiron 5447 on Compal board LA-B012P, noted for a Core i7 configuration; the tokens dx and bf are not explained, though bf may mean a dump taken before a change. The 8 MB binary matches a 64 Mbit SPI chip. Compal boards use the LA-xxxxP pattern printed on the PCB, so confirm it matches exactly. Keep a backup of the chip you remove and verify the image after writing with a programmer.
