Windows 10: Kernal DMA is on, but dashboard tells me it's off, why?

"Local security protection is off" through the core isolation heading, however, when I check through Windows Help it takes me to an article about kernal DMA. There's nothing with the security details where it tells me how I can actually fix this issue, or make any changes to it.

Virtualization Technology In Firmware and Kernel DMA Protection for Thunderbolt

I am wondering if the Virtualization Technology in Firmware needs to be enabled to ensure there is Kernel DMA Protection. Looking at my computers system information it shows that the Kernal DMA Protection is on but the Virtualization based security is not
enabled. Is this okay? Do I still have full Kernal DMA Protection?

 

Dma ?

On my sys. (sys. listed), how do I enable or disable DMA on my Sata drives? I have a Sumsung SH-S203b Dvd recorder (sata) and in the Nero info tool I get a warning that DMA is disabled on this drive. On my old sys. (P4C800-E Deluxe) the Intel raid driver software provided control of dma. On the P5K Deluxe where do I find the drive settings (DMA or PIO) and how would I change them?

Thank You.

 

DMA Devices?

When I go to "System Information" and expand the "Hardware Resources" tab and then click "DMA" (Direct Memory Access), the panel that lists the devices is blank, i.e. no devices are shown.

Since my hdd, ssd, NIC, sound card etc. normally are supposed to use DMA, I'm not sure why I'm not seeing them listed.

I checked Device Manager but there doesn't appear to be any way to verify if DMA is being utilized. I recall in prior versions of Windows, Device Manager would display a check box in one of the tabs for a specific device, that would indicate if DMA was active, but I don't see this feature in Windows 10.

Is there any other way to verify whether or not devices on my computer are utilizing DMA?

Thanks.
