Raw 4 MB BIN dump labelled as the mainboard BIOS of a Dell Inspiron N5110 with Core i5, according to the name. A 4 MB image fits a 32 Mbit SPI flash, so the chip on the board must be the same size for the file to be written. It is used to restore a board that fails to boot or shows firmware corruption, programming the chip directly with a tool such as a CH341A. Save the original contents before erasing, since service tag and other machine-specific data live in the flash.
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.
