I have an Asus A8N SLI, AOpen 1648/AAP(ROM), NEC ND-3520A (Burner), HD is SATA. Just to be clear the A8N has a Primary and Secondary IDE connector. What is the best way to configure the optical drives? Have both on one IDE cable or each on a separate cable? If on one cable, which should be master and which slave? If on separate cables is there a difference between the primary and secondary connector?
