Am I wrong ? and as I remembered I have an imap server and squirrelmail in it (that was slow on a PII 333MHz), I think that changing cpu freq would be great (unfortunatelly impossible as said) well, anything to make it draw less power :) thanks to you all, matheus -- We will call you cygnus, The God of balance you shall be
