BIOS dump for the Dell Inspiron 5520, labelled for a Core i3 configuration and marked as a second display copy, which most likely means an alternative or secondary image kept alongside another dump. The 4 MB binary is a raw SPI flash image meant for a hardware programmer such as a CH341A. Confirm that the chip on your board is 4 MB before writing, read and save the original contents first, and compare the board revision, because Inspiron 5520 boards were built in several variants with different flash layouts.
