Try using iPartition to flip the 'Startup' flag on the partition you installed to (or Drive Setup might be able to do it too, though this might only if that particular version was used to format the mac's internal drive). Also, don't forget to bless the system folder / system file.

I'd personally advise wiping the partition map and patch partitions completely (using dd under osx or linux), and formatting with Drive Setup 2.1 (for an internal disk) or 1.9.2 (for firewire).

Or use another tool like e.g. Silverlining 6.5.8 (downloadable from lacie site).

Hi, This copy booted in my iMac G4 17inch 2003, after I restored OS 9 it did not boot from HDD Sad I`ll try different methods and post here if I succeeded.

I also have an iBook G4(12 inch, 1.07GHz), but how to hack the nvram to make the OS 9 system folder bootable?

I can confirm that this image successfully installed OS 9.2.2 on my Power Mac Dual 1.42 Ghz G4 processor (FireWire 800). Thanks much for this image!

You need to make some nvram changes in Open Firmware to make the System Folder appear as bootable on G4 iBooks, however, the Radeon 9550 in that iBook is not supported by any OS9 extension so it gets stuck very early on booting up to a grey screen. Earlier iBook G4s can boot but only to 256 colours.

It cannot boot my 1.33 GHz iBook G4. The System Folder appears as "unblessed" when the CD is mounted on it. So I think this book ever booting to 9.x is out.
