If you are Win98 right click My Computer\Properties\Device Manager double click on drives then double click on the drive you want to enable you will see a box Under settings put a tick in the box, windows may say that it may cause problems ignore the warning and reboot the computer then go back to the above and see if the tick is still there if not then it cannot be enabled for that drive

You can follow the same rout for XP but look foe device manager under hardware

(1) Firstly, you can only enable DMA if motherboard support it.

(2) Even you can enable DMA, it may not make much difference because your HDD is spinning at low speed (5400rpm), most HDDs nowdays spin at 7200 rpm (some at 10000rpm). Moreover, you may short of HDD space which make access slow.

The best solution is to get a new HDD if the HDD is the one hold you back. £35 will buy you a 80gb (7200rpm) HDD click here. However, I do not think that the HDD is the only one holds you back for better game performance.

XP is slightly different from 98. Under Device Manager, click on the + alomgside IDE ATA/ATAPI controllers, then double click on Primary IDE channel, and click on the Advanced Settings tab. Similarly for the Secondary IDE channel.

XP will autodetect DMA if available.
