Thanks cybercore for the link. Excellent guide, very comprehensive. Read your reference pages and their links to addition pages 51 and 52, cannot figure out how to update the sigs on another computer? Unless maybe if you had the full retail version installed on another computer and then was able to build your own rescue disk from there? Is that what we're talking about? Pages 51 and 52 are both headed by "You must have an Internet connection to update." (in red).
