This is for Win2K but should apply to XP too. Click "Start > Control Panel > System > Hardware > Device Manager > IDE ATA/ATAPI controllers". Right click on the "Nvidia Nforce Parallel ATA controller", then click "Properties". Click the "Driver" tab, then "Update driver", "next", select "display a list of known drivers", and "next". You should see 2 controllers, the Nforce and "Standard Dual Channel PCI IDE controller". Select the "Standard Dual Channel PCI IDE controller", then click "next" to install the driver, then click "finish". When you close the "properties" window it will ask if you want to reboot, click yes. Upon reboot the system will redetect your IDE devices and may ask to reboot again. When you are finished you will now have in the device manager "primary IDE channel", "secondary IDE channel", and "Standard dual channel IDE controller" along with the Nvidia nforce Serial ATA controller.
You must now enable DMA in the primary and secondary IDE channels by right clicking each, click "properties", click the "advanced settings" tab, and select "DMA if available" for transfer mode, then click OK. You will again be asked to reboot click no after changing the primary and yes after you change the secondary channel. You should now have WIndows IDE controller installed with DMA on. Hope this helps with your burner.
