I just installed a LG-GSA4081B on my Yosemite G3 350. It works well under 10.3.2, even better with PatchBurn II (you get iTunes support). But if I try to start my Mac under Mac OS 9, not Classic environment, it does not start. Same thing for start from cd-rom holding C key down. Panther disc OK, Mac OS 9 nope. So, could an unsupported dvd drive to avoid Mac OS 9 launch?
