I have a 3COM509 network card configured to IO address 0x300 and irq 5, and
everything is working great when I restart io-net with following options:
io-net -d el509 -p tcpip
But my problem is that is I plug in a digital IO board (Octagon 5300 on IO
address 0x100) then the 509 driver cannot find the network card any longer.
I have tried specifying the IO address to the io-net command:
io-net -d el509 ioport=0x300 -p tcpip
but without any luck.
The funny thing is if I move the address of the Octagon board to 0x110 then
everything works again.
