I recently replaced my NEC DVD+RW 1100A With a pioneer 109. Now I want to reinstall the NEC to have two burners. Should I just plug it in and see if it works, or do I have to fool around with the master/slave thing? If i were to plug it in and see what happens could I mess something up? I guess I will wait for an answer before I ask further questions. When I tried to get a firmware update I had to mess around with master slave settings. Any info would greatly be appreciated.
