I know that option ROM is firmware code on adapter controller which gets initiated at system power-on. My question is, does that firmware code run locally on the adapter controller or on the system CPU? does that code ever need to be in the system memory?

It would help if you added some details like: Which adapter? What system? – alain Sep 27 '16 at 18:29

Let's just say, a network card or a SATA card – George Pu Sep 27 '16 at 18:36
