How do I check&change PIO/DMA status w/ insufficient privileges to Device Manager?

I use Vista. I can get to Device Manager and open Properties dialog for said ATA controllers, but it doesn't show the Advanced tab where you can setup PIO/DMA. This must be due to low privilege user account. Opening the Device Manager prompts a warning stating that I can't alter settings.

Is there, in this case, a safe way to:
A) Check the drive's current state for PIO/DMA (Is there a giveaway behaviour in dMC for example?)
B) Change back to DMA if it's been altered. (Maybe a command line method?)

PS. There is no way I can increase my account's rights on this computer, so please don't just suggest that route.

Vista seems to self correct the PIO problem given time (about 5 CDs, with PIO the CPU will be 100% if ripping to 'Test Conversion')

Test Conversion: CPU usage peaks to 100% only for a second or so for the parts when FLAC is being encoded. During ripping, CPU usage stays in around 5%.

I am assuming the drive is in DMA mode. Can you please confirm this?

Yes I would say so.
