But when I try to mount the CDROM with the -t cdfs and rest of the syntax as per instructions on the author's site (cdfs author) the system hangs. So I simply booted a copy of SMART Linux that I have which has that module on it and working. That did the trick. I'm wondering if the problem is that the latest cdfs version is for kernel 2.6.12 and I'm running 2.6.16. Oh well, worked around the problem. Thanks, Jacques B.
