The installation lets you check each one of the ISO's you've burnt without commiting to an install. Load up CD 1 and hit reset and you'll see for yourself. It does come in handy with me having burnt a guff copy of one of the CD's in the installation - about 3 in - before realising there is an easier way! Make sure it can read them all before commiting to an install. HTH Bry
