ROMs are simply how BMW differs each car based on features. You and I might have identical cars except maybe I have a heated steering wheel and you don't. That small difference can mean that you and I have different ROMs. I know that seems like a really vague explanation, and it is pretty simplified, but it really is just something on the ECU that differentiates the BMWs based on their features.
