I think there is a misunderstanding. Intel ME is a hardware feature. Yes there is some flash memory which contains more code and an operating system, but what is stored in flash memory is only part of Intel ME.

Peter Stuge from Coreboot noted during his 30C3 talk that even if you completely zero out the flash, it is possible for Intel ME to send a network packet out of the ethernet interface. The cutoff point when this started happening is the 965 chipset around 2006.

It is a hardware feature, but it does basically nothing without its software in flash....

The only code that is inside the silicon is a 128K bootrom that literally just sets thing up for the real firmware to run.
