I downloaded the update from the Taiyo site and extracted to floppies. Before starting the update of my KN7 to 1.5 I did the disc check procedure. Disc 1 seems to be o.k because I got the message to change disc 2/2. After finishing the check of disc 2/2 the display gives the message "NG Disc" and there is no message for starting the update. Does this mean that disc 2/2 is not correct?
Does NG mean No Good?
