I'm not surprised that the really low-level hardware-accessing stuff might not run properly from Parallels. It is, after all, an emulation box.
I originally installed Boot Camp because I needed to run comm tools (commercial router initialization and boot servers) that I thought would be too low-level for Parallels, but Parallels turned out to handle it admirably. I ended up using the Boot Camp partition from Parallels almost exclusively, and finally used the Parallels tool to pull the partition into a Mac VM file to eliminate the pain of having to maintain two distinct backup regimens. Parallels offers the ability to completely usurp devices (including drives) from the Mac OS for exclusive use, so I wouldn't be surprised to learn that the low-level stuff may actually run at this point. I suspect if you gave them a phone call and asked specifically if some named tool ran they could tell you. > On Jan 18, 2018, at 9:12 AM, Dinse, Gregg (NIH/NIEHS) [C] > <[email protected]> wrote: > > Hi, > > Thanks for responding.
