+## Reducing Intel Managment Engine firmware size
+
+It is possible to reduce the Intel ME firmware size to free additional
+space for the `bios` region. This is usually refered to as *cleaning the ME* or
+*stripping the ME*.
+After reducing the Intel ME firmware size you must modify the original IFD,
+split the resulting coreboot ROM (See: Splitting the coreboot.rom)
+and then write each ROM using an [external programmer].
+Have a look at the [me_cleaner] for more information.
+
+Tests on Lenovo W530 showed no issues with a stripped ME firmware.
