DVD burner using PIO not DMA

[Darfur]

My DVD burner is set in device manager to use DMA if available, but it's using PIO, causing my CPU to eat through cycles while reading from a disc.

Any idea why it's not using DMA?

Could be that you are using a damaged cable, or a standard 40-pin cable, instead of a ATA-66/100/133 80-pin. It's possible that the device is sharing a cable with another component that is running in PIO mode, which would force both devices to run as PIO. You might also need to upgrade the chipset drivers, and/or the firmware for the drive.

It may be necessary for the IDE channel to be uninstalled and reinstalled before the device will function correctly as DMA.
