How to make a bootable CD an all Mac ?

[fleny68 <fleny68@free.fr>]

Hello,

I used a script derived from 
http://cvs.debian.org/boot-floppies/powerpc-specials/mini-iso.sh
to make my knoppix MiB ppc bootable.

Unfortunately, the CD seems not to be bootable on the powerbook 12", and maybe 
on other machines? 
What is the way to make a cd bootable on all Mac?

thanks,
