PCI on TP400 from DSPDesign

Has anyone used the TP400 from DSP Design under QNX ? Attaching a PCI device
to the PC104 stack causes the io-net service to fail (symptoms: ping doesn’t
work). The Ethernet device is PCI but in a different slot to the other PCI
board. I’m not sure why there is a conflict. Without the extra PCI board
ping is OK.

Any pointers appreciated !!
