1) mkdir
2) copy files
3) mkisofs -r -o cd_image
where: cd_image is the name of the file you want to create for burning as a data file.
4) cdrecord -scanbus (shows your device driver for your cd recorder)
5) note the node (e.g. 0,0,0)
6) cdrecord -v speed=16 dev=0,0,0 -data cd_image (creates the cd from the cd_image you generated)
7) note: use -overburn in case you are a little over the warning amount.
