Hi,
It seems my MAC address is 00-00-00-00-00-00 !
How is this possible? And what can I do? Networking works fine and in
fact I'm writing this now on the computer with this NIC.
If I run 'tcpdump' on a linux box that acts as the gateway for this
computer, I can indeed see thha the MAC is 00-00-00-00-00-00. Check the
outputs below.
If anybody has any idea what's going on I'm *very* interrested. I find
it especially interresting that the linux-box (the gateway) is not
complaining at all about this! Thanks alot.
I'm running WindowsXP Pro (no servicepacks) on the system with this
funny NIC.
The network card is built-in to the motherboard so I can't check it in
anothe machine.
Here's the outputs:
