Dell 3020 BIOS package marked A15, delivered as a 4.41 MB RAR archive. A15 matches Dell's usual lettered BIOS revision numbering, although the name does not say whether this is an OptiPlex or another 3020-series model. Confirm the exact system before using it. The contents may be a full SPI dump or an update image, so inspect the archive first. Before programming the flash externally, read and save the existing chip, because that backup holds the service tag and board-specific data. Also make sure the file size matches the chip 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.
