DMA on 2nd IDE channel

Comment:
On my PC, the Primary IDE channel is set for "DMA mode if available. The secondary IDE channel controller said PIO mode on both devices, one is a CDROM, the other is CDRW. Is this correct, or should I change the secondary IDE controller to "DMA if available"? Is there any valid reason to leave the secondary channel in PIO mode?
