Eric: Remember that software and firmware have to be compatible. So, if you installed from your CD, it would be mismatched. Since you have Beta firmware on your Book Port, then you'll need to put Beta software Version 2.1.0.97 on your new computer.

This was the beta download. When I switch to a new computer, I will have to download that same or a later version and cannot go back to using what came on the install CD? Thanks! Eric SS
