Accessing Intel Mobile Express Chipset SATA AHCI Controller for DMA  

Am running a new Lenovo G570 laptop with Windows 7 Home Premium. Attempting to access my IDE ATA/ATAPI controller (Intel Mobile Express Chipset SATA AHCI controller) to check for DMA settings. Getting nowhere, because what I get is a message that tells me it is working properly. No opportunity to see whether or not it is running as DMA or PIO. The computer has Intel Core i3 installed, and the driver was preinstalled when I purchased the machine. Have attempted to rip a DVD, and while it worked, it took a looooong time to load and the result was not particularly useful (short homemade DVD that duped three times!). Is it possible to access settings beyond "working properly" so that I can be sure that the rip/burn process is OK? Help appreciated! Thanks, Jacko.

Non: Many thanks for the leads. Will check them out to see if there are some nuggets of wisdom buried therein. Guess nobody ever said life was easy!

NoN: Thanks. Did find out a couple more things about this issue. Downloaded a copy of 1Click DVD Copy Pro and ran a rip and dupe with it. Worked OK, tho' a little slow, but hey, it worked. Noted in the log that the chipset is indeed IPO (it's address/name is HL-DT-ST DVDRAM GT33N LEO1(Ide). This tells me (I think!) that I should go to Lenovo and ask them what the story is. No harm in trying, and I might find out something that could be useful to anyone else in this predicament. Will keep you posted. In the meantime, thanks again for your help. Jacko.
