BIOS firmware archive for the Dell OptiPlex 9020 in the MT (mini tower) chassis, marked as tested by the FST Fix repair team. The RAR is 6.35 MB and the name does not list the board number, flash chip or individual files inside, so open it and inspect the contents first. Desktop dumps like this are written to the SPI flash with a programmer such as a CH341A when a board will not POST after a failed update. Read and save the original chip before erasing, and confirm the image 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 @generalbios. Enginerys does not host this file.
