IT WORKS !!!!!!!!
That's wonderful !!
Last time it didn't work because my collegue gave me the wrong gateway IP
This time I checked myself and used the right one and it worked !!
So the card module is ok !!
ifconfig eth0 even gave me the base addres (0xd000) and the irq 9 (I think)
so the interaction with the hardware is correct !!
I pinged his machine and no packet went lost !!!
Thank you very much to the all of you !!
Now I can install and update from the net !!
P.S. you'll hear from me soon...
