During the boot, all the screen is used (1280x854) but the desktop is displayed centered in 640x480.
I'll try to install it this week-end, formatting the internal drive but I haven't been able to make nvramrc work (I get a gray screen after reboot, even with the CD).

I am now able to boot from the internal hard drive without having to enter OF commands before (using nvramrc thanks to some of the posters in this thread).

ATI Jasper Extension does not seem to solve the 2 active monitors problem but I found a way to get the screen native resolution: in the Monitors control panel, go in the disposition option and then move away one of the screens from the other, your main screen should now be in its native resolution (albeit with only 256 colors in my case).

But still, it's pretty cool to be able to boot into OS9. The last problem I have is that my PowerBook sometimes defaults to booting on the OS9 partition even if I select a Mac OS X partition in the System Preferences.

Re: Mac OS 9 on Unsupported Hardware

I've been following this entire process with great interest and finally got around to somewhat giving it a try.

I have a 15' Powerbook G4 1.5ghz (Powerbook5,4) with an ATI Mobility Radeon 9700, that was able to boot the install CD using nvramrc. I was able to get to the install desktop (with the dual display problem outlined in other posts; center of screen only) but didn't go any further.

My machine is available for anything needed to further this process. Just ask and thall shalt receive...

Re: Mac OS 9 on Unsupported Hardware

No luck with my Powerbook G4 !.5 (PowerBook5,6), after the OF hack I can boot from the installer CD but the Mac freeze and bombs before finishing the boot.

Re: Mac OS 9 on Unsupported Hardware

I can confirm this works with my Late 2004 iBook G4, however with a few caveats. Here's what I did to get it working:

1.  Do the NVRAM tweak to allow the system to boot.
2. Install from the universal unsupported disc that was posted earlier in this thread. Don't reboot yet!
3.  Delete the Multiprocessing and ATI Video Accelerator extensions from your hard drive while you're booted from the CD. With the multiprocessing one, I was experiencing the same problems some other users had with the loading bar freezing about 95% through. With the ATI one, I was experiencing freezing when I got to the desktop, and you don't get any acceleration anyway.
3. Reboot.
4. Download the ROM files posted earlier in the thread to a FAT32 formatted flash drive (I was on Windows). Unzip them to the root directory of the hard drive with Stuffit.
5. Reboot from the CD again and replace the ROM and other files.
6. You're done!

Caveats:
1. Brightness controls seem to be backwards. Pressing the brightness down key displays the brightness lowering in the OSD, but raises the brightness of the display, and vice versa. That's why when you first start the installation after changing out the ROM, the screen is completely off.
2. The thing gets REALLY hot. Like, 1st generation Unibody Macbook Pro hot. It doesn't seem to be turning the fans on either. Adding some power-saving changes to the Energy Saver control panel seems to fix this a bit, but it only goes down to really hot (as opposed to REALLY hot).

Re: Mac OS 9 on Unsupported Hardware

Could the same principles used ITT be applied to run OS 8.6 (or even earlier) on an OS9 locked computer? There's lots of software out there that would really benefit from that downgrade...

Re: Mac OS 9 on Unsupported Hardware

I think that's stretching it a bit, sadly.

The reason being that since support in OS 9 is marginal at best, I doubt if 8.6 would fare any better.

Never know though. It was thought to be impossible to run OS 9 at all on these machines, so maybe someone will figure it out?

Re: Mac OS 9 on Unsupported Hardware

Hello ! I tried to install OS 9 with Centris' commands, and it worked. But with the new files from the iBook rom, Mac OS 9 booted with a black screen. I then tried to remove them, but now, everytime I boot to anything (Even the boot menu) the screen lights up for half a second, and then goes black (but the computer still works, which is odd !). I wondered if anyone of you had an idea about what I could do? Thanks !

Re: Mac OS 9 on Unsupported Hardware

Wait, no, nevermind. I actually feel really dumb, the screen just turned off with the Mac OS 9 update, I thought it wasn't working since I couldn't see anything on it. My bad !

Tho I wonder, is there a way to make my AirPort card recognised on Mac OS 9? It doesn't see it! Is it because of the command to fool the installer by any chance?

Re: Mac OS 9 on Unsupported Hardware

Regular AirPort, maybe, since the OS 9 drivers exist. AirPort Extreme, no. You'd be better off with one of the game adaptors that look like Ethernet ports to the computer. My TiBook has one of these, powered off the FireWire so that it's even self-contained.

I've got a ton of topics to catch up on. So while I try to find time for the rest, who's the boffin I should search/approach for a progress summary on my 12" PowerBook G4/133? Would that person and the discussion/info be better searched here or over at OS9Lives?

Hi JT,

If you could throw me the model identifier for that machine, I can give you a better idea of the support status of that model. Being a 1.33GHz 12", I'm guessing it's a PowerBook6,4.

I would take a look at the disk image and instructions in this thread first:

OS 9 Universal Installer CD (For Later & Unsupported Macs)


There are a couple of things to be aware of. Firstly, those machines have PowerPC G4 7447A CPUs. Mac OS 9 seems to have some issues booting on 74x7 CPUs (7447, 7447A and 7447B), but you can temporarily get around this issue by tweaking the CPU identifier so OS 9 thinks an older G4 (7450/7455) is installed. This can be done via Open Firmware, and the instructions to do so are available here:

OS 9 Universal Installer CD (For Later & Unsupported Macs) - Post #14

Don't forget to note the information at the end of that post about trashing the Multiprocessing folder.

Without the Open Firmware trick, OS 9 will fail to boot beyond a grey screen. With the Open Firmware trick in place but the Multiprocessing folder not removed, OS 9 will likely still boot, but hang somewhere during startup or loading the desktop.


Secondly, some peripheral devices won't run correctly at this time. The PowerBook G4 12" 1.33GHz uses an nVidia GeForce FX Go5200 graphics processor, and there are no drivers present in Mac OS 9 to support this GPU. As a result, video performance will be significantly reduced and other video anomalies may occur. Sleep mode will also likely fail to work correctly.

Other devices, like AirPort Extreme cards, will also fail to work. USB 2.0 ports will run at USB 1.1 speeds, and FireWire 800 ports will run at 400 speeds.


If you do manage to install OS 9 onto the hard drive, it is recommended you download the Macintosh ROM v10.2.1 "Generic" update from this post - Mac OS 9 on Unsupported Hardware - Post #120 - and copy those files into the system folder. I've corrected a few bugs in this version that are still present in the OS 9 Universal Installer CD. It's possible that the iBook distribution of the ROM will also work and correct some issues with backlight control (the PowerBook G4 12" and iBook G4 have a lot in common), but I haven't tested it.



As you can probably tell, this is definitely still in a proof-of-concept stage and some significant work is still required to make it a usable system, but if you're in this for the sake of experimenting with it or just having some fun with it, then by all means go ahead.


Cheers,

~ iMic.

Re: Mac OS 9 on Unsupported Hardware

Hey, I just wanted to report back on my attempts at booting OS 9 on my 12" iBook G4, it's the 1.33 GHz (PowerBook6,7). Incidentally, it is also one of the very last PowerPC laptops released. With the OF hacks in place, and using the universal CD, it is recognized and will boot past the grey screen. It gets pretty far in booting, loading most of the extensions, before hanging and eventually just giving me a bomb. This also occurs if I boot with extensions disabled. I'm not well-versed enough in classic Macs to even theorize what's causing it to hang, other than 'it's too new', but I can confirm that it does not complete a full boot.

Re: Mac OS 9 on Unsupported Hardware

Hello,

Just checking in to report an iMac G4 1 GHz 17" (PowerMac6,1) working great on OS 9 using the Universal Installer CD (For Later & Unsupported Macs) and latest 10.2.1 ROM by iMic. Thank you!

However, there are still some things not working:
- AirPort present but not detected - why?
- Brightness control - iBook ROM does no good
- Sleep
- Built in speaker

Also, how should I tell if video acceleration is actually working?

I love this machine and OS 9 suits it best so, sould I have any hope on the above?

That iMac G4 has an AirPort Extreme card. Apple never produced an OS 9 compatible driver for the Extreme card, only the original AirPort (802.11b) cards.

Marian wrote:

Possibly related to the video driver, or maybe the iMac G4 uses a different device entry in the Open Firmware device tree for the backlight. I haven't checked although I do have a PowerMac6,1 iMac, so if I find some free time I'll check.

Marian wrote:

Could be related to the video driver again - the iBook G4 does the same thing.

Marian wrote:

- Built in speaker

Good question on this one, I'm not entirely sure.


Marian wrote:

I tried running the Quake III Arena Demo for OS 9. It requires hardware video acceleration and won't run without it, so it's a pretty decent test. If you have iTunes 2.0 for OS 9 installed as well, open it and try dragging the window around. Without hardware acceleration the window redraws tear and chop pretty badly (however iTunes itself runs fine).


I'm not currently developing any modifications to Mac OS 9. That isn't to say I won't again soon, but it's a difficult job to reverse engineer an operating system for which there is little documentation of the low-level system, and I'm not the most qualified person for the job. What I've accomplished already is about as far as my knowledge can handle.

I have a bundle of 4 iBook G4s (PowerBook6,5) coming in within the next couple of weeks though so if I find any free time I'll see if I can knock down the PowerPC 7447/7457 compatibility issue. That's a serious if though.

Thank you very much for stretching all this to the current state--much appreciated! Hope you will power on that iMac G4 and do your magic when you have the time.

Regarding the AirPort in the PowerMac6,1 not working, sorry for asking smile totally forgot it was the Extreme version inside there. As for the rest, thank you for replying!

Re: Mac OS 9 on Unsupported Hardware

I currently own a PowerBook5,7 (PowerBook G4 Aluminum 1.67 GHz 17 inch, A1107). It has similar hardware with the a1106 that cc333 owns. I tried it without the cpu-version method, booting from OF, and it halts at the same grey screen. I will try with the cpu-version hack when I have free time.

Re: Mac OS 9 on Unsupported Hardware

Isn't there any good news about booting a Mac Mini (PowerPC 7447A G4) into MacOS 9 yet?

It would be such a fine (little!) device to run the legacy MacSystem on it. _o.O_
