But what exactly should I check? How do I know if there are conflicts?

Sorry, I forgot to put the other one (02:00.0 Ethernet controller: Intel
Corporation 82574L Gigabit Network Connection). My intension is to make
RTNET work, but leaving eth0 for non RT networks and eth1 for the RT
EtherCat network. Anyway, I haven't been able to make it work at all (I'm
getting the errors posted in the previous e-mail).

Yes, this is the non RT driver I've been using. I've tried to install
rt_e1000 and 8139too. After removing the e1000e driver, I run the script
'rtnet start' and I get the errors, but I see that the modules rtnet,
rtipv4, rt_e1000, rtpacket, rt_loopback,rtcfg, rtmac and tdma are
installed.
Nevertheless, when I type ifconfig it's displaying just 'lo'. Should I see
rteth1 when the installation is correct and I type ifconfig??
Also, where can I check the cards supported by each driver? I just found a
list in the rtnet site http://rtnet.org/doc.html. Is that list complete? If
it is, I guess I would have to change my NIC, since both of them are Intel
8257x.

No, the gcc version is 4.4.3 (Ubuntu 4.4.3-4ubuntu5).
