NetworkCard of IBMthinkCentre

[H S Rai <hsrai@gndec.ac.in>]

I installed Debian3.1 on IBM Think Centre using CD. It has 
BroadCom's NetXtreme fast ethernet card. The driver is 
present. But it is not loaded automatically. On issuing command:

# /sbin/modprobe tg3

It says "cannot find proper PCI device base address, 
aborting. 
/lib/modules/2.4.27-2-386/kernel/driver/driver/drivers/net/tg3.o: 
init_module: No such device."

Is there problem with irq or base address. How to set them? 
In M$win card works fine. In Debian, card's light glows.

Thanks in advance.
