    Hi guys,

    The problem I am having is a bit tricky. Its about the question that people have asked hundreds of time about enabling DMA under windows XP. Well a few months back I was trying to enable DMA, but it just wasnt working out. Then I changed the drivers of my IDE Controller from Microsoft drivers to Intel drivers and DMA got enabled.

    Now I used Nero Info Tool (was having some problems with my CD Drive). The output I am getting is in the picture below (q1.jpg) It shows that on one of my HDDs, on the 80GB (Operating drive), DMA is enabled. But on my 250 GB drive DMA is not enabled.

    Now all the online articles about DMA say that in the Device manager you have to go to the Primary Channel, Click on Properties and Advanced Settings to enable DMA. I am adding another screenshot of that Properties window (q2.jpg). It does not have the Advanced Settings Tab at all!! Any ideas?

    Things I tried/ checked:
    • Ensured that the data cables were 80 conductor cables
    • Uninstalled the channel and re-booted so that windows would detect it again and enable DMA/ show the Advanced Settings dialog box.

    I tried all possible options, but theres no way of doing this. So either the Nerocheck tool is reporting it wrongly or I do not know the solution. I tried using the DMACheck utility (which is actually meant for Windows NT 4.0), but it did not work.

    Have you tried clicking on the Secondary IDE Channel and see what comes up in Device Manager.

    Are you saying you installed Intel Application Accelerator for your drives? If so the DMA settings are made through the Intel program not in Device Manager.

    Yeah, I have installed Intel Application Accelerator... And the Intel Accelerator says that DMA is enabled on both drives and shows their status as UDMA-5 which is fine. But Nero InfoTool shows DMA not enabled on one of the drives. Is this a problem with Nero InfoTool? I mean because the drivers are NOT the windows drivers, it might not be able to read the DMA registers. Is this possible?
