So from what I understand of what you said, upon coming to life, the CPU reads instructions from ROM, which instructions say "Copy all the startup instructions here in ROM to RAM and then set the program counter to such-and-such beginning address in RAM." Is that about right?

@psusi Do you have some links explaining what you're talking about? CPU shadowing isn't getting me much, and how it could be configured. And when are you talking about? When did motherboards have this option? Can you point to any models of motherboard that would've had this option?
