Good point, I've also run the fileio.exe on qemu (with the configuration 
options described in the QEMU-RTEMSWiki) but still there seems to be no 
network interface (I guess ne1 should be there). Everything works, all the 
shell commands are present, but it looks as if the "--enable-networking" 
flag has no effect at all. The same happens with rev. RTEMS 4.9.3. I'm 
sure I must be missing something, but I just cannot figure out what.

Thank you very much for the info, I'll give it a shot. Anyway, I guess I 
should get a successful simulation on qemu in the first place.

OK, thanks a lot for your comments.
