I never seen any cd32 that boot into amiga OS. Maybe other's got some info how to do a cd32 auto-boot, that loading wb or amigados. Anyway if you have done this, then you should put(install) whdload and shadow of the beast on that cd and then you can run it.
Propably you need a desktop amiga (or pc with winuae) to do this.
So you make a cd wich contains amigaos, installed whdload and the whdload version of beast. (Because the original game was made trackload system so works only floppy.)
