Dell OptiPlex 3000 desktop BIOS for motherboard 222004-1, marked tested, in an 11.9 MB RAR archive. The dash-suffixed board number matches the Wistron pattern, the ODM that supplies many OptiPlex boards. Use the image to reprogram the SPI flash when the system has no video, beeps, or bricked after an update. The archive is large for a single dump, so check what it contains. Match the board number, back up the existing chip, and verify the image size equals the flash 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.
