How do I check to see if DMA is enabled for the hard drive and CD writer.

Hi,Open up device manager and then open the sub folders
Click to expand...
(the + sign) for IDE ATA.ATAPI controllers. Due this for
both Primary and Secondary IDE Channels.Right click and
select properties then the advanced settings tab this
will show if DMA is enabled.Which is a faster burn than
PIO settings.If PIO is set then select "use DMA when
available" from the drop down menu, then right click and
select uninstall, that IDE channel will be removed.Reboot
and it will be reinstalled by windows and "should" be set
to DMA. Sometimes this setting will revert back to PIO
why I havent figured that out yet.
 
Thanks for the info.

I wondered about that one myself, until I came across this:
