Ok, just rechecked it and the motherboard NIC is really Attansic L2 Fast Ethernet aka Atheros.
And I pulled out the pendrive to see which extra.lzma I was using and it's yours.
But I already tried using yours on 1.02b, and the result was the same... I guess I should compile my own drivers?
Output:
[ 4.193800] usbcore: registered new interface driver ethub
[ 52.885279] jme: JMicron JMC2XX ethernet driver version 1.0.8
[ 53.052902] usbcore: registered new interface driver kaweth
[ 58.944397] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 58.944433] atl2: eth0 NIC Link is Up<100 Mbps Full Duplex>
[ 58.944442] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
Looks like I'm using wrong driver?
