I want to disable the built in ATI RageII on my beige G3 in OF - so it is not seen by any OSes. Can this be done easily?
I dont have any Forth knowledge.

Short answer: No.

Long answer: KNowing what the boot checks are which find the devices and present them to the OS requires more than a knowledge of Forth. You'd also know what the routine does, where the addresses are stored etc. Plowing through the Forth routines in OF can end up overwriting boot checks etc and leave your machine unable to boot anymore. There used to be a member here, Louisgarberg or something like that, who worked for Apple on its OF team. He would be the guy to ask, but I think he got tired of this place.

You could try on the Apple forums.
