Søren:

Outstanding! The drive is now recognized at boot, I can read and write 
CD's, and even listen to audio CD's. It all seems to work! Such a small 
change had a huge impact.

If you don't mind, what exactly was the purpose for making the change 
(other than to make things work)?

Thanks for everything,
Patrick
