I cant seem to enable my second dvd burners DMA. Dell Dimension 8400 Dual Lite-on DVD burners set on primary IDE drive 160GB ATA second IDE drive The hard drive is the secondary drive because its ATA,and i dont know how to change that. The DVD burners are the primary because they are IDE. Thats how dell sent me the computer and i only Installed the two DVD burners.TOP burner is the master and second is slave. Ive tried unsatlling the drivers and rebooted,just the Master and Hard drive is DMA enabled.
