BIOS firmware for the Dell Vostro 3470 desktop, in a 7.50 MB RAR archive. The name gives only the model, with no version, board number or chip details, so inspect the extracted image and its size before use. Such dumps are programmed into the SPI flash with a hardware programmer to recover a system that will not post after corruption. Dell images contain service tag and system data, so back up the original chip and check that the image size matches its capacity.
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.
