Hello, first post for me... I have searched, but getting a little lost!

I've managed to get my Powerbook 'Aluminium' 15 inch 1Ghz booting into Mac OS9 using the open firmware hack detailed below. I have everything working, except there's no audio device (so no sound, internal or external). Is there anything I can do to get the sound working? The post I followed was years old, so I'm hoping there's a better way to do this... or possible updated audio drivers?

Any help very much appreciated:-)

dev /cpus/PowerPC,G4@0
80010201 encode-int " cpu-version" property
dev /pci@F2000000/mac-io/i2s/i2s-a
" screamer" encode-string " compatible" property
device-end

Thanks to Greystash, I tried the mentioned nvram code without the screamer part and my audio works perfectly!

So for anyone with a Powerbook G4, 15 inch 1Ghz, you only need the following code:

dev /cpus/PowerPC,G4@0
80010201 encode-int " cpu-version" property
device-end

Glad you got it working!!

would this work with a Apple PowerBook G4 1.5 12" (12-Inch 1.5 GHz - M9690LL/A* - PowerBook6,8 - A1104 - 2030) ?

i need help, which method did you use to boot into mac os 9 CD / FW external / hdd partition ?
i have the same 1GHz PPC G4 Powerbook aluminium, but i cannot get it to boot into mac os 9 CD or FW ...

i read this & they specify the location of the iso or image but it seems to have vanished
or at least to me it says :

The topic or board you are looking for appears to be either missing or off limits to you.

I managed to get Mac OS 9 installed on my PowerBook with the help of some posts I've stumbled across (nanopico, iMic, and others) and the CD image located at http://macos9lives.com/smforum/index.php/topic,2143.0.html.

thanx !

p.s. to be precise i downloaded already a couple of iso's
https://www.macintoshrepository.org/126-mac-os-9-2-2-universal-installer-2013-macos9lives-edition-w-cpu-5-9-rom-10-2-1-for-unsupported-g4-like-fw800-mdd-emac-

& also here of course: http://files.macos9lives.com/MacOS%20Operating%20Systems/Mac%20OS%209.2.2%20For%20Previously%20Unsupported%20G4s/Mac%20OS%20922%20Unsupported%20G4.iso

tried to boot from CD / FW external drive
but niente, nothing, nada , nougaballs :-/
