Firmware dump for the Dell OptiPlex 7440 All-In-One, for the mainboard identified by the code IPPSL-BF, marked tested fix in the archive name. The image is intended for direct SPI programming when the machine fails to post or the firmware has been corrupted. Check the code printed on your board before writing, because AIO models can ship with different mainboards. Make a full read of the original flash and save it, verify the image size matches the chip, then program and verify with an external programmer and clip.
