I'm not the original poster, but unless you're talking about a very simple embedded system, most computing devices have lots of areas for malware to live that will survive power cycles. HDD firmware, graphics card firmware, various controllers have their own firmware, NIC cards have their own firmware, etc.
Even if the boot device is read-only, it would be a huge challenge to build any kind of system without these vulnerable components.

It's certainly far more doable and reliable than ensuring the software doesn't have holes in it. There's a huge market for secure items - routers, cars, thermostats, medical devices, avionics, ATMs, etc. I simply don't understand why ROMs aren't used.
