How do you enable DMA on XP

[Zubeen]

hi,
i have install windows xp sp3 on my computer but the problem is i can not enable DMA (Direct Memory Access).Its suggested to have already installed the motherboard drivers for chipset, usually that way windows enable DMA automatically.before installing a fresh copy of win xp, dma was working properly.

hi,
Windows XP reverts to PIO mode after several attempts to use DMA mode have failed. If this had happened, Windows XP will not return to DMA mode even if you instruct it to do so. Microsoft considers this a safeguard, but many users find this feature confusing. In order to manually reset the access mode, you can uninstall the drive and reboot. Windows will detect the drive at the first boot and use it. You can then set the access mode to DMA, and Windows will use that setting. Of course, if there is a real problem using DMA mode, Windows will revert to PIO mode again. You may want to consider alternative burning software and verify that it doesn't cause Windows to retreat to PIO mode.

To enable DMA mode using the Device Manager

1.Open Device Manager.

2.Double-click IDE ATA/ATAPI Controllers to display the list of controllers and channels.

3.Right-click the icon for the channel to which the device is connected, select Properties, and then click the Advanced Settings tab.

4.In the Current Transfer Mode drop-down box, select DMA if Available if the current setting is "PIO Only."
If the drop-down box already shows "DMA if Available" but the current transfer mode is PIO, then the user must toggle the settings. That is:

Change the selection from "DMA if available" to PIO only, and click OK.

Then repeat the steps above to change the selection to DMA if Available.

This is the right method of enabling dma on per device basis, try it, this will work.
