I did it, but i must have made some error, because it didn't boot afterwards...
Good news is that i learned how to use my provider's Rescue System, it worked perfectly, yeah!
So, now that my server is back from the dead, can i ask you a favor to tell me what should i add in the lilo.conf?
This is my lilo.conf:
This was what i added (and it didn't work):
And, finally, here's the contents of /boot directory:
server1:~# dir /boot
Many thanks in advance!
