Firmware image for the Dell OptiPlex 9020 desktop, the 4 MB file, labelled as tested by FST Fix. It pairs with an 8 MB image for the other flash device, so the board uses two SPI chips that must each receive the correct dump. Check the chip markings to confirm a 32 Mbit part before programming, as an image that does not match the chip capacity will not fit. Write it with an external programmer, keeping a backup of the original chip so serial and tag data can be restored.
