I read on [the Wikipedia article on DMA attacks](https://en.wikipedia.org/wiki/DMA_attack) that a misconfigured BIOS allowed for this type of attacks. I am asking whether, given the hardware I am using, DMA attacks are possible and whether I can mitigate them by changing options in my BIOS.

In my case, I own an [Asus P8P67 motherboard](http://www.asus.com/Motherboards/P8P67/) and a netbook. I guess on the Netbook a DMA Attack would be impossible because it has no FireWire connection port and no PCI Slots. Is that correct?

In my Asus P8P67 BIOS, I can't find an option to disable DMA. Is it possible to disable all PCI slots except the one my graphic card is plugged in to? If I do this, would it suffice to prevent DMA attacks?
