I recall having the same or, from somewhat vague memory, similar problem=20 some time ago. It was about the time when CD drives started being commonl= y=20 installed as master on the secondary port instead of as a slave. At that = time=20 moving the CD to slave fixed the problem. But then it might not work with the current round of difficulties.
