10.1 is too early a system to run on that PBG4; they came out after 10.2, and will most likely ship with only whatever they came with or later versions of the OS. Similarly, OS 9.2.2 is the only version of OS 9 you can boot; earlier versions don't have the model-specific information necessary to run the machine, and there is nothing after 9.2.2.
