I don't have a dual core at my disposal but it works for hyper threading. -Jim Interesting. If you actually look through the information from the type 4 second, I'm guessing it would be clear to the eye that there is or isn't a processor installed though, correct? Sounds like your way is the easiest though. Ray True. Curiosity got the best of me when I ran your "type 4" method and 2 returned when I knew I only had one CPU installed...after looking at the output, you are right, it's clear the second processor is not installed. ...I'm surprised no one has mentioned the "open the case" option :) -Jim -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subjecthttps://www.redhat.com/mailman/listinfo/redhat-list
