BIOS image for the Dell OptiPlex 7040 desktop, labelled as working, in a ZIP of about 7.5 MB. The name gives no board revision or BIOS version, so compare it with the hardware before use. Dumps like this are written to the motherboard's SPI flash with a programmer such as a CH341A when a system will not start or stays on a blank screen after a bad update. Save a copy of the original chip first, since it holds unit-specific data such as the service tag, and confirm the file size fits the flash.
