make sure to include support for scsi and scsi emulation in your kernel. just go through the menus in make xconfig till you find it.
you need to add the line
to your /etc/lilo.conf. (replace hdd with whatever your cdrw drive is)
if you included support for scsi emulation in your kernel as a module you will need to add the line
# cdrecord --scanbus
to check it worked, you should get something like:
bash-2.05b# cdrecord --scanbus
