Is there a way to programmatically set ‘DMA if available’ for Windows 2000/XP/2003? My problem is that ‘PIO Only’ is set for tape drives by default but our tape drive supports DMA. Currently the customer has to go to the Device Manager to change. I would like to use a coinstaller to change to ‘DMA if available’ during driver install but I am not sure how to go about it. For example when I change DMAEnabled it doesn’t have any impact.
Thanks!
