I wanna get os 9 working on my iBook G4 (Late 2004) but i have hit a roadblock

I downloaded the ISO file from here: http://macos9lives.com/smforum/index.php/topic,2143.0.html
I burnt the disc at 8x speed and put it in my laptop, but when i tried to boot from it all i got was a gray screen.

After googling for a bit i found a script that modifies the nvram to work but that didnt help...Do any of you have some ideas?

Here is the script i tried:

#!/bin/sh
echo Enabling OS 9 booting...
echo "You may have to enter your password"
# Use nvram command to setup nvramrc with script to make open firmware changes
sudo nvram nvramrc='" /" select-dev
" PowerBook4,3" encode-string " model" property
" PowerBook4,3" encode-string " MacRISC" encode-string encode+ " MacRISC2" encode-string encode+ " MacRISC3" encode-string encode+ " Power Macintosh" encode-string encode+ " compatible" property
00000000 " graphic-options" get-my-property 2drop !
unselect

" /cpus/PowerPC,G4@0" find-package if drop " /cpus/PowerPC,G4@0" find-device 80010201 encode-int " cpu-version" property then

device-end \ PLX-OS9-PATCH
'
# Enable use of nvramrc on boot. Change to "false" if you want to disable again. Or just clear/reset nvram.
sudo nvram "use-nvramrc?"=true
echo done.

As far as I know, nobody has been able to successfully run OS9 on the iBook.

That said, I'm thinking that you should at least get an error message or something when you attempt to boot.
What did you create the CD on? If it was a Windoze PC there may be an issue.
Go back to and re-read line one.

Sorry for the late reply, different timezones.

I burnt the OS 9 image on my Hackintosh running OS X 10.10
What do you mean by: Go back to and re-read line one.

Really? Maybe a larger font…

Not true. Well depends on your definition of boot.
I had used the ROM I made that disabled the machine type check and modified the CPU Version during boot.
It boots just fine.  There is one problem. The track pad is so slow that it is not usable. A usb mouse works and everything (except airport) works as well. 
Setting it up required target disk mode. Run the installer from another machine and then manually switching the ROM out. 

[Doggoli]

Don't have another machine...I guess i am outta luck, thanks for help though!

[nanopico]

It is possible without another mac, that was just the process I used.
I can't remember if that was the machine I had to disable the audio on to get a full boot.
I have OS X on it right now, but I don't use it.  I can walk through getting it booting without help of another mac and post here the steps required.

If its no problem that would be great!

Certainly will do. Might take a couple days when I get a few moments.

[GaryN]

There you go. If Nanopico says it can be done then I believe it.
He's one of those guys that just does shit that nobody else even thinks of.

[Doggoli]

There you go. If Nanopico says it can be done then I believe it.

Glad to know that! i'm new to this community and so far everything has been really cool..I just hope i can get OS 9 running, also , could i dual boot with leopard?

[GaryN]

Sure you can. You should read this: http://macos9lives.com/smforum/index.php/topic,2671.msg24015.html#msg24015

It pertains to another machine and install, but just note the parts pertaining to having to two dual-booting.

Hey Everyone, I know this is old but I was stuck with os9 not booting and managed to get it working  back by fidling directly into open firmware and recreating the bash script that got shared manually into the nvramrc var in OF. for some reason it says that my post is marked as spam so I created a gist here hoping this helps someone else https://gist.github.com/naruse/6a6aff9b9adce04d31b06632bd8b1eb4

[naruse]

Dont despair, this took me ~2 weeks of fidling back and forth with it and a lot of chatgpt, so use it and ask it about the output you get in open firmware. hopefully the link I shared above can help someone else get unstuck!

I've been running OS9 on an iBook G4 12 1.0 for many months tbh. https://everymac.com/systems/apple/ibook/specs/ibook_g4_1.0_12.html

I thought it would never work but it bloody runs great apart from it needs a restart in every 5 or 6 times upon fresh boot. The desktop icons start flashing so I have to force a reboot, which sorts it. The original battery still lasts about 4-5 hours, bonkers. Model is the 1.0Ghz 12" with 1.25GB ram. I run Reason 2.5, Logic Pro 6.4.3. and I recently purchased a legit Mac version of Cubase 5 VST. Interfaces wise got a Metric Halo ULN running and need to see if my old M-Audio 1814 works. (MT4 for the midi)

It has the stock 4200rpm drive so I will need to try the SSD upgrade soon. However, it looks pretty shit from what I've seen. Over the past 2 weeks I've taken apart 2 Titaniums 550 and 1Ghz and re-applied the thermals on a quest for a quiet OS9 laptop. No chance. I noticed an improvement on both but not a feckin patch on the iBook. Powerbook 12 867 close second but the iBook is the winner for me.

I got all relevant info from here. http://macintoshgarden.org/apps/mac-os-922-boot-file-ibook-g4

Big thanks to top dude darthnVader btw - Mac OS 9.2.2 for unsupported iBook G4 series Macintosh notebooks. This method uses a modified boot ROM created by darthnVader (MacOS9Lives).

Many thanks,

could we make a list of all models in the style of everymac just for powermacs and which method needs to be applied to get os9 going generally and specifically on some models that require special mods

[Bolkonskij]

That's a great idea. Let's open up a specific thread for collecting the info

[ssp3]

All the information is available on this same board, only that some of the posts that are buried further down need to be pinned.
I personally posted solution for two Al PowerBooks an I think I've made two more that I haven't posted yet.

P.S. I am a mod here because of the Mini displays thread, but I'll leave pinning to the forum staff.

[smilesdavis]

what is pinning?
