Setting DMA and Display Settings in Windows

[FlashX]

Direct Memory Access (DMA) is frequently used for data transfer directly between memory and a peripheral device such as a disk drive.
If you encounter difficulty with your DVD-ROM setup, the DMA might not be turned on.
Check the DMA and confirm that it's turned on.

To turn on DMA in Windows 2000 -

1. In Control Panel, click the System icon and click the Hardware tab.
2. Select "IDE ATA/ATAPI controllers".
3. Right-click the Primary IDE Channel icon and select Properties.
4. Click the Advanced Settings tab and select the DMA check box (if it’s not selected already).
5. Click OK.
