See if this helps any, not sure what size card it was from as it was just a pic I traced out to repair a similar mishap awhile back for another forum member...

If that doesn't help any get me a good pic of your board and I'll see what I can figure out on it.
Also, if you actually have a schematic of the motherboard or DVD drive I'd be very interested in seeing them, though I figure you mean pinout diagrams instead which aren't anywhere near the same thing as a schematic.
