Main BIOS image for the Dell Latitude E6520, 8.00 MB, with the name noting an i3 version, so it came from a unit with a Core i3 processor. The trailing 2 is unexplained and may mark a second dump. The size matches a 64 Mbit SPI chip, which pairs with the separate 2 MB power chip on this model. Confirm the board, read and save your original chip, and restore the service tag afterwards if the donor data does not match.
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 @bios_laptop. Enginerys does not host this file.
