How to enable/disable DMA:
WinXP/2000:In the Device Manager expand the IDE ATA/ATAPI controllers entry, either by double-clicking IDE ATA/ATAPI controllers or by clicking on the + next to it.
Select the appropriate IDE channel (Primary or Secondary). To get to the IDE Channel Properties window, either right-click the channel and then click Properties, or select the channel and click Action -> Properties in the menubar.
In the Primary/Secondary IDE Channel Properties window, select the Advanced Settings tab (if the Properties window does not have an Advanced Settings tab, see the Note at the end).
Choose either the Device 0 frame for the master device on the channel or the Device 1 frame for the slave device on the channel, depending on whether the drive for which you are trying to enable DMA is master or slave. Click the Transfer Mode pull-down menu. Select DMA if available. Then click OK.
Note: With some IDE chipset drivers DMA cannot be enabled through the Device Manager, but only through the driver settings. An example of this is the Intel Application Accelerator.
