I have DN19 and DN20 now and it doesn't work. Only because the INT mapping on the riser is not right? http://www.morex.com.tw/drawing/MAR122-J%20Drawing.pdf shows some IDSEL jumper with ADxx numbers. What could these be? Photo at http://www.morex.com.tw/products/imgproduct/100-1.jpg. Still DN's? >> This Morex riser has DN20-31 or so, so more options. > > OTOH I wonder how do they use DN 21-31?

So at least try the different jumper settings (without additional info, I hope Morex responds to my emails). Else do a little soldering. > It's possible that the riser card includes a bridge, though.

Looking at the photo I don't think I see a bridge... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
