eth0/eth1 disappeared after changing mother board

My eth0/ eth1 disappeared after changing the mother board where the network card is embedded. My OS is OpenSUSE 10.3. I have made no other changes to the system and there was no BIOS or any other upgrade. Booting off a live CD works fine.

ifconfig -a shows only the loopback interface and nothing else.

lspci shows the two network cards: "Ethernet controller: Broadcom Corporation NetXtreme BCM5755 Gigabit Ethernet PCI Express (rev 01)"

"lsmod | grep bcm" and "lsmod | grep tg3" shows nothing - this tell me that the network card kernel module is not loaded.

yast->hardware->hardware information shows the complete details of the network cards.

"lspci -v | grep -i ether" shows

3f:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5755 Gigabit Ethernet PCI Express (rev 01)
Subsystem: Hewlett-Packard Company Unknown device 1308
Flags: bus master, fast devsel, latency 0, IRQ 218
Memory at e3000000 (64-bit, non-prefetchable) [size=64K]
Capabilities: <access denied>

I did a cat /etc/modprobe.d/module-renames and tried "modprobe <module>" for the following modules listed there but I get "module not found"

bcm-new aic79xx-new bcm4400 bcm5700 bcm5700-new carmel e1000-new lpfcdd qla2100 qla2200 qla2300 qla2322 qla2400 qla6312 qla6322 tg3-new

I have also tried modprobe tg3.o, modprobe tg3.ko - I did a search and found all the modules exist on the system.

I have also edited /etc/udev/rules.d/70-persistent-net.rules and changed the MAC addresses there since they were holding the old network cards MAC address.

Under Yast -> Network Devices there is only Network Card, Modem, ISDN and DSL options. I used the Network Card options and tried to (A)dd the card there but since the system cannot see it (as the module is not loaded), it's of no use.

Thanks for any help.

Try modprobe tg3

If I try modprobe tg3, I get nothing. No error, no nothing.

Does it just return to the prompt? What happens if you then type in

lsmod | grep tg3

Does it show up? What's the output of dmesg after you run the modprobe?

Yes, it returns me to the prompt.

Unfortunately, I am not near the box at the moment. And not having a network connection makes things even harder. I wonder what would happen if I try lsmod | grep tg3 and it shows the module.

I am pretty sure when after I tried modprobe tg3, I also tried ifconfig -a and it showed me nothing.

All I needed to do was type: insmod /lib/modules/2.6.22.5-31-default/kernel/drivers/net/tg3.ko and it's all back up and running.

However, I lose network on each reboot and need to type the above. Does anyone know how to fix that?

Thanks.
