I just got my first dvd burner and I installed it and everything seemed to work, but Nero infotool says dma is not enabled. I thought it might be bios settings, but it wasn't. I then uninstalled intel application accelerator and that fixed the problem. Is there something wrong with IAA (intel application accelerator)? Do I need it anyway? On the intel site they act like it makes a big difference, does it? Also, my computer had 2 drives installed and both were set to cable select. I replaced the secondary slave drive with my dvd burner and set it to slave. Will this configuration work if I don't change the first drive (master) from cable select to master? I just didn't feel like removing both drives, and since it seems to work, I'll probably keep it like this unless someone tells me otherwise. Thanks in advance!
