I solved installation problems, now I can install RTNet without problems. I
also recompiled the kernel but I'm not sure I did the right thing: in
"Network device support", "Ethernet(10 or 100 Mbit)", I selected
"EtherExpressPro100" (my device) with M, so it should be loaded as a module.
I recompiled my kernel but nothing seems to be changed: when I do "rmmod
eepro100.o" the answer is that "eepro100.o" is not loaded (in fact it is not
loaded!), and if I try to do "insmod eepro100-rt.o" the answer is
"init_module: no such device...". Did I miss something when I configured my
kernel? Do I have to select as a module all the devices selected with * in
"ethernet (10..)"? 
Sorry if my questions look stupid, but I'm quite new to linux.. :)

I don't speak Italian, but according to a translator webservice, it 
seems that you are trying to install RTnet into its source directory - 
please specifiy an independent folder instead.

If the Linux NIC driver is already part of the kernel, yes!

You forgot to load a realtime NIC driver (something with a "-rt" 
postfix) before running rtifconfig.
