Firmware for the Dell OptiPlex 7470 all-in-one, board IPCFL-GL, with the CSME region cleaned and tested OK on a 9th generation Intel processor. A cleaned Converged Security and Management Engine region lets the system regenerate ME data rather than carrying over corrupted or machine-bound state. Program the image to the SPI flash with an external programmer when the unit fails to post. Read and store the original chip first, confirm the board code on the PCB, and check that the file size fits the chip.
