The above seems to say that an Ethernet controller from Intel was found but it was not recognized. And finally, the result of ifconfig:

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:4 errors:0 dropped:0 overruns:0 frame:0
TX packets:4 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:200 (200.0 b) TX bytes:200 (200.0 b)

Thanks in advance for your ideas.

I found that Intel has a web page for Linux drivers: http://www.intel.com/support/network...linux/e100.htm
