I think you should uninstall your IDE Busmaster drivers. Go to Device Manager and IDE/ATAPI controllers. You should see Pimary and Secondary channels and then a third item.. Probably says Busmaster with some other stuff. Right click and uninstall this. Reboot your computer and let it redect your drives.
DMA should be automatic, but you may have to turn it on manually.
This should work. If it does not, please update your IDE drivers. Depending on what hardware you have, you'll probably end up going to
www.viaarena.com ,
www.sis.com , or
www.intel.com for the drivers.
If this still doesn't work, you have some sort of other problem I'm not familiar with.
