BIOS dump for the Dell OptiPlex 3280 All-In-One, with the board identified in the name as IPCML-IP and marked as tested. Dell desktop and AIO boards often carry such IP-prefixed codes rather than ODM numbers, so check the label on your board before relying on the image. The 8.37 MB archive is meant for recovery when the AIO shows no POST or a corrupted firmware region. Use an SPI programmer, save a full read of the original chip beforehand, and check that the extracted image matches the chip capacity.
