Hiya all.

In late May, I ordered myself an iBook G4 from Amazon for $90. I did this because I wanted a PPC Mac to mess around with. It came with Mac OS X 10.5 (latest on PPC Macs.)
I came by this while searching "how to install Mac OS 9 on iBook G4" on Google one day.

I downloaded the Unsupported G4s version of Mac OS 9.22. I burned it to a CD, and put it in the iBook.

I went in Startup Manager. There was 10.5 but the 9.22 CD appeared as well. I tried booting from it but it stayed at a grey screen.
I did a bunch of research. I then found this command to type in OF:

" /cpus/@0" find-package if drop " /cpus/@0" find-device 80010201 encode-int " cpu-version" property then

" /cpus/@1" find-package if drop " /cpus/@1" find-device 80010201 encode-int " cpu-version" property then

device-end \ PLX-OS9-PATCH


I did this command, and booted the CD in OF this time. SUCCESS!

Now that I knew it booted 9 successfully, I didn't want to waste my 10.5 install. (I don't have a 10.5 CD.)

I went back in 10.5 and used SuperDuper! to clone my HD.

Now that's done, I booted back into 9 and initialized the hard disk. I then installed 9.2 successfully, but removed the Multiprocessing extensions.

I will post the results of booting 9 from the hard disk soon.

Any update on this?

Ok, I'm very sorry that I haven't gone back to this more than a year ago! I'm still alive though.

The iBook did boot up and I went through the initial setup. All was OK! I did some tests as well- The modem doesn't work, and there's no WiFi using AirPort. I expected this.

I also made a YouTube video for this follow-up: https://youtu.be/7wwlUY710_c


Thank you all so much! If anything else happens, I'll come back to this thread and report.

Hello everyone,
I just downloaded "Mac Os 9.22 unsupported Hardware"
I try to open the .iso file but osx considers it damaged.

I can burn it with osx 10.5 Disk Utility but I can't boot on ibook g4

Has there been any success bringing support for the Radeon 9200 to the iBook G4 under OS9?
It boots with the primary detected screen at native resolution but when loading the system it picks up the second "display" at 640x480, and you can't switch out of this.

I could disable this via Open Firmware but I was wondering if there has been any similar modifications to the Mac OS ROM or NDRV (like darthnVader's modified Jasper driver) to get the full selection of colour depths?

After scouring darthnVader's posts I found this one where he's already modified a version of the PCI drivers and swapped device IDs:

I can never thank you enough darthnVader! Very happy
