Well I would guess Yamaha made some DVD ram drives but that was OS 8 drivers. That's going to be the issue is drivers for system 7. CD Rom tool kit may have something that will work as its for 7 and used as generic as it could for many drives. I do not remember DVD being an option before the beige PowerPC and all the drives I see in mine at home are IDE for those. None of my nubus powerpc's have DVD drives just all stock CD Roms, but ill keep looking.
