I have it set to master and it is a Nec 3500a. It has worked perfect in my other computer but when i installed it in this new one i am having some problems. I ripped a movie with shrink just fine but cannot get that to burn it just sits there and never starts. Same with decrypter it says its starting but does not. Both the dvd drive and cdrw drive show up as scsi which seems strange to me. I also tried to upgrade to the newest firmware and it gives me a patching error. Argh, what to do?!!!
