Hi !

I've got a problem to get the
NVIDIA M2075 PCIe x16 GPGPU Card in PowerEdge C410x
to work with (at this time for two) C6145 :-(

... lspci shows nothing about them :-(

After disable all special PCIE-BIOS-settings,
one machine shows the controller :-)

4a:00.0 3D controller: NVIDIA Corporation Tesla M2075 Dual-Slot Computing Processor Module (rev ff)

The other machine shows nothing :-(

Both machines are connected via the the default port-mapping
IPASS mapping to PCIE Controller

Mapping 1

1 -> 1,15
VS
5 -> 2,16


But i can't build the nvivdia-drvier on the machine with the detected 
TESLA M2075
