Archive for the Dell OptiPlex 3020 desktop, spelled optilex in the name and marked as tested and working by its source. At 9.20 MB it most likely contains a BIOS dump, although the contents are not listed and should be inspected after unpacking. Such a dump is normally written to the board's SPI flash with an external programmer when a failed update or corrupted firmware leaves the machine dead. Before flashing, read and keep the original chip, confirm the image size matches the chip, and note that service tag data may need restoring afterwards.
