Longer answer, at the time we had no free general CD driver. We had permission to include the eltorito driver and I forget the exact brand but also have permission to include a closed source one that unfortunately worked with older CD drives and not modern ones (around 2005 era, so really wouldn't work with current drives probably). So I started reading the specifications and implementing one. It works for some definition of work, but was never completed. Jack made his available and so I never got back to it when I had some time. I had a more advanced version than released but lost sources a long time ago. I do not have it in public source control (only private git repository now), though it is/was somewhere on my fdos.org site. > Jeremy >
