Installed the original OS 8 on a G3 Lombard laptop, then installed OS 9 on top of it. Ended up with 2 system folders. OS 9 was running fine. Then I used the control panel app to set the boot folder to OS 8, and it booted into 8. Problem is now I cant get back to 9 ? The OS 8 boot selector only shows the main Mac HD not the folders. Pressing Option has no effect? Any idea what I need to do to boot back to OS 9?
