I just installed the latest drivers for the HPT366 ATA/66 controller on my Soyo SY-6BA+IV, and now I don't have an option in device manager to enable DMA on my Quantum Fireball Plus KA HDD. This same setting on my Kenwood CD-Rom won't stay enabled either. I wonder if it is already enabled on my HDD? I don't know about my CD-Rom though. Any help would be appreciated.😕
