I can't find where I read about the 3 PCI buses, I thought it was in the 
manual but now can't find it.
PCI.exe reports all the onboard stuff on PCI BUS [0], the ATI AGP card 
on BUS [1] and the network card plugged in as on BUS [2]
I've had problems with this network card previously in another computer 
where it stopped working shortly after boot which was fixed by moving it 
to another slot.

Only one UART here which is using IRQ#4
