Intel Flash Image Tool build 16.0.15.1554, supplied as a 14.8 MB .exe for Windows. The utility comes from the Intel CSME 16 system tools package and is commonly used on laptop and desktop boards to decompose a BIOS dump into descriptor, ME and BIOS regions, edit settings and assemble a fresh image. A typical bench use is rebuilding a corrupted ME region before reflashing with an SPI programmer. Confirm the target board runs a compatible ME generation and back up the chip first.
