RLV12 placement in H9278-A question

[John A. Dundas III]

Perhaps someone could clarify, the manuals are less than explicit on 
this.  What kind of slot can the RLV12 be placed in?  Does it need a 
Q22/Q22, Q22/CD, does it not matter, or are there jumpers to 
accommodate either?

Before I fry something I'd like to make sure I've got this right.

Thanks,

John
