Yes - you need to use SCSI emulation to use an IDE burner. It
sounds like you have the writing part working, so I would bet that
the /dev/cdrom now just points to the wrong device. /dev/sr0 is most
likely the device you're looking for (the first "SCSI" cdrom device).
Try mounting this device with a data cd in the drive with:
mount -t iso9660 /dev/cdrom /mnt/cdrom
where /mnt/cdrom is an available directory on your system.
If you can mount this device and read the contents of the CD, then
you probably just need to symbolically link /dev/cdrom to /dev/sr0
to get your existing /etc/fstab entry to work properly - I can't
say for certain, as I'm running Debian.
