DMA mode not available

[Ted Anderson]

I'm trying to troubleshoot super slow XP performance on a clean install (P4
1.7 was plenty fast under ME) and everything seems to be pointing to the
IDE controller. Following advice here, I found the latest Intel chipset
drivers for my particular motherboard, and the driver date is now 2002
instead of the standard 2001 MS drivers.

However, in trying to follow other troubleshooting advice, I see that there
is no advanced settings tab for my IDE controller. All I have is General,
Driver, and Resources. As far as I can see, there is no place to even
verify DMA mode in the controller or hard drive properties in device
manager.

How can I verify DMA mode is being used and if necessary change it from PIO
to DMA?

Thanks.

Sounds like you installed the Intel Application Accelerator.
If you did, you won't see the advanced tab under your hard drive controller.

Instead, the IAA comes with its own companion software that will allow you
to change the DMA/PIO modes.

Yep, you hit the nail on the head! I installed both new drivers and the IAA
as the MSI (motherboard) site wasn't clear about what I needed. The Intel
Application Accelerator seems to show that the IDE controller is using UDMA
mode 5, but as far as I can tell I couldn't change it if I wanted as there
is not a wrench icon by that property. I guess I will keep trying to find
the cause of this annoyingly slow performance.

If you got the 'Intel Application Accelerator' drivers from
http://downloadfinder.intel.com/scripts-df/Product_Filter.asp?ProductID=663
then you will find the menu entry for it in Start - All Programs
and it will tell you for each drive what DMA mode is in use. It does
not provide any controls - it assumes you want the best mode that can be
sustained.

If you did not get that download, then do so
