Thanks! I will try that as soon as I find out how to talk to
the beast. =)

Lovely. So does that means I need to open the case or lscfg
will do the trick?

Beleive or not, I do have the key. It is still in its
keyring with a copy key and a little metal tag. =)

Thanks! Now, would single-user mode allow me to change root password?
