Should I enable my DMA / PIO for my burner?

Sorry asking such a silly Q. Assume I don’t have the CD burner manual. How do I know whether I need to enable DMA for better performance ?

Another question is if I have a choice to enable DMA or PIO, which one should I enable ??

Please kindly advise.

Always enable DMA over PIO. DMA decreases cpu usuage when reading from the burner or when burning with burner. PIO does not do that.

Hi max_clif

Many thanks for your concise Explanation : )

And more important, DMA is faster then PIO! So the chance of bufferunderruns is smaller.
