Is your PCI card a real 3,3 V card? The IceCube (Lite5200) board
only supports 3,3 V cards. No 5,0 V cards and no 3,3 V/5 V mixed
cards are allowed.
Because of an unfurtunate design of the Lite5200 board it is
possible to plug in a 5 V PCI card in reverse direction into the
3,3 V coded PCI receptacle.
