At the Apple Store they are now selling MDD PowerMacs with the feature of OS 9 Boot Supported!?! They took it away, and then gave it back? I find this very interesting. Also, this must mean there is indeed a way to get the MDD PowerMacs to boot OS9. Whether it is done via software or hardware is the question.
