A firmware dump labelled Dell 15 3000 grafix, which points to an Inspiron 15 3000 series laptop, probably a version with a dedicated graphics chip. The exact model number is not given, and the 3000 series covers many boards. The 8 MB size matches a 64 Mbit SPI chip. Use it with a programmer to recover a board with a corrupted BIOS, but only after checking that the board number and graphics option match yours. Keep a backup of your original chip.
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 @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
