Working BIOS for the Dell OptiPlex 5040 small form factor desktop, board SR205 with PWB revision A00, supplied as a 12.8 MB rar archive. A dump like this is written with an SPI programmer such as a CH341A to recover a machine that will not POST, shows power LED errors or has corrupted firmware. Desktop Dell boards may carry service tag and ME data in the image, so read and save the original chip first. Confirm the PWB number and revision match and that image size equals 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.
