Hi Thanks for replying.
Not too sure what is meant by spamming own thread, but I couldn't find a relevant thread to list this question on.
The switch in question is the micro switch on my case which is activated whenever the side panel is removed.
It is currently disabled in the BIOS so it has no effect. I just couldn't find any reference to it the the DQ6 manual.
It is actually mentioned as a 'feature' of this mobo, just not sure where to connect it on the board!
