10.8.5 running - but 3 simple questions

[bru3]

Hi All!

I've updated my ML to 10.8.5. Gigabyte X79-UD5
After that it took me 5 hours to find all the settings needed to be changed that it works again, I still have 3 questions.

1. change npci=0x3000 to npci=0x2000
2. add dart=0 to boot file
3. tried update HWMonitor to newest release to get rid of smcReadKeyAction ERRORs in logfile. (still not working)

1. It would be great to know what the difference between those are.
2. in 10.8.4 VT-d was working great with parallels 7 !!! Is there a way to fix this problem without deactivating VT-d. Could it be, that it has to do with the parallels driver?
3. Which version of HWMonitor is needed to get rid of this Error logs? I now have 8.3.887 installed.

I tried really hard to get a answer to those questions but all I've found was advices to do it...
Thank you for your answer!

Did you ever find a solution to your vt-D problem?

Sadly I didn't.

I will upgrade my system to Mavericks soon but I don't think this will solve the problem.
The strange thing is, that it was working in the previous version.
Even the motherboard beeper was beeping when I booted a OS in parallels desktop.
