Hi, I am new to YellowDog, and try to install it on a Mainstreet machine. I have a 4.0 version of YellowDog, and have used its installation manual to the point where the YelloDog CD 1 is supposed to be inserted. The system will not recognise the CD even though I have used it on an other machine with luck. What can be wrong? Sincerely Ådne
