Check your Hard disk controllers in the device manager. If they are ATA then you won't get dma on the hard drive. You need the buss master controller and the primary and secondary bus to all be IDE. Here's is how you fix that:1. update bus master driver to IDE (standard dual PCI IDE controller)2. restart.3. remove the standard dual IDE PCI controller.4. restart.5. Now the primary and secondary will be IDE, but the bus master will be ATA. Simply update the driver back to the standard dual PCI IDE.6. restart. 7. go turn on dma in disk drives.
