ML350 Miniport Driver - No Controllers Detected

[ccoho]

I'm trying to apply the following fix:

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03395859&lang=en&cc=us&taskId=101&prodSeriesId=4091412&prodTypeId=15351

to my servers but i'm running into an issue.  In the resolution section of the MS KB in that article (http://support.microsoft.com/kb/2468345) it mentions creating a registry key in the <MINIPORT> service, where <MINIPORT> is the name of my miniport driver.  I have no idea what that name would be.  It is an ML350 G6.  Can anyone point me in the direction of where to make this change?  

I am thinking it is maybe the HPCISSS2, which is the 2nd driver to update in the fix, but I want to be cautious and try to confirm that before actually making the change and causing major problems if its wrong.

Thank you
