Hi,
Found this problem on a si3114, but should be applicable to any controller that has seperate raid and non raid drivers.
The si3114.sys gets loaded BEFORE si3114r.sys. This causes problem if you have configured a raid set since that will not be recongnized by the first driver. The si3114r.sys has to be loaded before si3114.sys for correct behaviour.
This can easily be fixed by changing the order in the driver pack inf file.
