Firmware archive for a Dell 6520 laptop, labelled for the NVIDIA graphics variant, packed as a 5.13 MB ZIP. The name gives no board number or version, so open the archive and inspect its contents before use. Technicians use dumps like this to reprogram the BIOS SPI chip with a hardware programmer after a failed update or corruption. Confirm that the machine really has the discrete NVIDIA GPU, back up the existing chip, and make sure the image length matches the flash device capacity before you write it.
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.
