It appears to be working perfectly now. The only problem is that I don't want my 8x CDROM sitting in my experimental Dell where I plan to do UNIX stuff that isn't multimedia strained. It would be great if you could post the patch. Is it difficult to insert the patch? So I would have to recompile the kernel? thanks in advance, Kelvin : This problem is caused by older "cheap" CD-ROM Drives, but there is : a work around. I submitted a patch to the author of the driver. I am : not sure if it has made its way in to the FreeBSD tree yet. If : people want it. I can post it. : Basically it is a timing problem. The CD-ROM indicates that it has : something for your computer, but it doesn't set the phase correctly : until a little while after. So a simple delay loop until the phase : gets itself sorted out works wonders. There are other problems with : the audio support, but it has nothing to do with this :) : M.
