I used one last with with FC4. If CentOS 4.x is not too different, you can
simply ignore the moaning in the cdrecord documentation about having to use
ide-scsi and /dev/s* devices, and test by using a good friendly tool like
"k3b" to detect and test your CD burner. The author of the cdrecord devices
used the ide-scsi module to get the IDE based burners to look like SCSI
devices because of the better functionality of those drives and those
drivers. Despite his religious objections, this hasn't been necessary for
some time (at least since the first 2.6 kernel I used, possibly longer) and
you can simply tell cdrecord and the DVD burning devices to use the /dev/hd*
device. I've written to him: he refused to alter that part of the cdrecord
documents.

As people said, /dev/ entries are now created with the udev tools at boot
time. But you don't need these, I think. Test with k3b.
