+--------------------------

+If you happen to be running multiple cards, it would be advisable to load

+Here the order of the card id is important and should be the same as that of the
+physical order of the cards. Here card=0x71 represents the Twinhan and clones
+and card=0x87 represents Fusion HDTV5.
