Burning
you'll need to make a system.cnf file and link to your elf, then you'll need CDGenps2 to create the image.
You'll have to set the lba of system.cnf to 12231 (I did for ps2link anyway. might be different depending on the nature of your work)
then just open up a burner (I use alcohol120) and burn it like any other cd.
(That's cds anyway, dvd-rs might be different.)
Edit - Goes without saying, you'll need a method to boot cd-rs, like disc swap or a mod chip.
