enabling DMA in XP

[Ranjan]

My HD & CD drives don't show option of enabling DMA, these are 18 month old
drive & were working fine under win 2000 pro.
Where as XP does not show these properties in device manager. I tried
uninstalling & reinstalling too, that does not work either.

Using Nero info tool I get to see the following:
Primary IDE channel
master DMA is On
Primary IDE channel
slave DMA is Off
---------------------------------

Secondary IDE channel
master DMA is ON
Secondary IDE channel
slave DMA is Off.

See this very thorough and helpful article about the PIO/DMA issue by

Update
Un-installing the Intel application accelerator did the job, it blocks these
DMA settings for some reason.

Hope it helps others having this problem.
