Mac OS 9.2.2 (Mac mini G4 Only) - Bootable ISO v9 (Updated March 2020)

Contains Modified ROM & Hacked Video drivers.
No Crazy Open Firmware commands to type, just Boot and Install !

NOTE:
Four years in the making, this install is intended for Mac mini G4s (1.25, 1.33, 1.42, 1.5 Ghz.) only.

If your PPC Mac with USB 2.0 is NOT a Mac mini, but you would like it to boot a native Mac OS 9, then try this method:

(Text copied over from: http://macos9lives.com/smforum/index.php/topic,4365.0.html) <-- login required.
All kudos for this dedicated work go to the people at Mac OS 9 Lives.

Insert CD and boot your Mac Mini while pressing "Alt".
On the boot screen select the OS9 CD (tab) and start booting (enter).

OS 9 is working flawlessly on my side, only the Mini´s internal speaker is not working.
During installation, my Logitech mouse did not work, an Apple hockey puck did.

Oh dear... No old games expecting OpenGL seem to like my installation. The only one I've found to work is Quake II - at about 1 frame per second.

Anyone else ? Or just my set up ? Mac mini G4 (machine speed in System Profiler reported as 1417 MHz).

An update on my noisy fan issue.

One thing about my mini that I find annoying is the fan will start spinning really fast when I launch certain apps, e.g.; Virtual PC, SimpleText !!!! etc...

I seem to recall that classic Mac OS's on PPC hardware were supposed to be more efficient if Virtual Memory was turned on in the CP's. But if a Mac had 1GB or more of RAM it cannot be switched on.

It hadn't occurred to me before, but in classic Mac OS's, by creating a RAM disk using the Memory Control Panel, my built-in 1GB RAM dropped down below 1GB and Virtual Memory became available.

App's are now running quietly and the mini feels more responsive too. I can use the RAM disk as a scratch disk for Photoshop, so I see this as an all-round improvement.

Easy to do with the mini G4 as it's RAM ceiling is 1GB and falling below this doesn't take very much effort.

[Edit] perhaps I got a bit excited with this. Running Virtual PC gets the fans whirring again, perhaps not as loud but it's still there. Oh well I think it's an improvement just not perfect, yet.

Thanks again for adding this to the MG! - I have now officially retired my eMac and my Mac mini G4 is my only classic PPC Mac without an OS X to boot up to.

It is really great to have a reliable unofficial 9.2.2 running on this G4.

An old FW drive should be delivered next week

Nice, for multiple OS boots? I purchased a Newer Tech FW enclosure a few years back and that has really come in handy at times. Even tho' it's FW 400 only, it's still fast enough to boot and run additional OS's via the Mac mini.

I thought I'd run into a gotcha with my OS 9x on the mini today. I'd installed ClarisWorks and it was crashing when loading "Claris XTND System", requiring a System reboot. I was fretting thinking it wasn't going to be compatible with this mini... Turns out there were a few bad fonts causing the issue. I found this out by running another Claris app, ClarisDraw, which has built-in bad font detection and logs them. Removing the logged bad fonts cleared the way for ClarisWorks to run OK. I still like having ClarisWorks around.

I mod my MDD to be totally silent, why not make the mini silent too.

I use the 1,25Ghz model because they are a lot quieter.

Guess I´m accepting the fact that there are silent Minis - would not have bought it, if I knew before.
There was no unreasonable fan noise on my side so far, the 1.5 GHz Mini runs hotter than the 1.25 GHz one, producing more heat than a 25% speed gain should account for.

An old FW drive should be delivered next week, maybe something springs to mind then?

I´m doubting we will see a matching ROM for the silent Minis any time soon.

Any plans for the mini 1.5GHz? It would have to be the ultimate G4 Mac mini, hardware-wise.

I'm almost ready to scrap my old eMac for parts. I've transferred all of my files, apps, etc over to my new OS9 mini and am just cleaning up before pulling the plug on the old chap. Yep, it has finally come down to this Crying

One thing about my mini that I find annoying is the fan will start spinning really fast when I launch certain apps, e.g.; Virtual PC, SimpleText !!!! etc. The fan runs really fast and is noisy, but spins down after about 30 or more seconds, to a quieter level.

I seem to recall that classic Mac OS's on PPC hardware were supposed to be more efficient if Virtual Memory was turned on in the CP's. But if a Mac had 1GB or more of RAM it cannot be switched on.

My mini has 1GB of RAM and I'm toying with the idea of reducing this to 500MB and having VM enabled, to see if that helps. But perhaps there is another option, such as running apps in a RAM disk, or something... Any thoughts on how to get the mini's fan to stay dormant? I love the quietness of it when it does run without the fan buzzing away at a zillion revs.

Thanks Mike, the more "expensive" USB soundcards ($ 3 to 5) do not have the faulty transcoder chip.
The monitor speakers won´t go over 12 kHz seemingly, so the frizzling is not noticeable - almost.
But you know its there. Sad

For the underlying problem, the silent upgrade Mac Minis will need a different ROM for OS9 than the original ones - too many hardware changes. Personally I´m doubting we will see a matching ROM for the silent Minis any time soon.

Pity about the USB sound adapters, 24bit, that must be why they ended up in the crap box Sad

Are you all out of options for the mini 1.5? Have you tried powered speakers via the audio out jack?

Pulled out some simple headphones and recalled in an instant
why the 3D Sound devices went to the crap box.
The devices are of bad workmanship and can not be recommended for anything better than crappy monitor speakers.

There is stereo output, but all three greenish CMedia put out a constant high frequency noise, a variable frizzling. So please do not buy these, spend two dollars more to buy something with volume buttons like the CMedia Headphone device 0X000C / 0X0D8C if needed.

Yes, sound from QT mp3 files is better than I expected.
I had minor issues with these cheap devices in Windows 10 or Mojave.
Thats why they went to the crap box.
Old Mac Mini and old sound transcoder chipset seem to match well. Smile
Never would have guessed that MacOS 9.2.2 already had working generic USB sound drivers.

CMedia USB "Soundcard"

That looks nice, 24bit. A good solution. Works OK now? I hope so.

I´ll give up with the headphone jack, but I´m still curious how other silent upgrade Mac Minis (1.33 or 1.5 GHz) behave with OS 9. (Hm, silent upgrade - nomen est omen?)

The "solution" here seems to be a cheap USB audio "soundcard" working without additional drivers in OSX or OS9. As the device is running from the passive keyboard hub together with the mouse, it is not even occupying a precious USB port.
The device is seen like this in Tiger:
CMedia Electronics, vendor 0X0808, device 0X8086.
Got three of them for 1 € each (shipping included) from China a while ago.
Looks like these devices are still available via ebay.

Can someone confirm this type of Mac Mini not playing sound in OS 9 via the headphone jack?

Maybe there's a clue in this Mac OS 9 Lives topic: Audio Issues on 1.5GHz Mac Mini G4 ?
Requires a registered member login to view - which I don't have (but I think you do), I'm hoping there are some hints in there that may help, and it's not just an unanswered question.

I didn't know about the 1.5GHz "silent upgrade" model, until your posts here. It comes highly recommended on the MorphOS morphzone site, if you can't get any headway with OS 9 audio and you decide on an alternative OS to try it out with.

As posted below, the Mac Mini G4 "silent upgrade" does not play sound via headphone jack - or to be correct, there is sound, but very near the audible limit.
I´m afraid the silent upgrade has gotten so many feature upgrades, that another hacked OS 9 would be needed. See the picture below:
Blue PCB, different Mezzanine card, different CPU cooler are obvious.
There are also some changes on the logic board.

Can someone confirm this type of Mac Mini not playing sound in OS 9 via the headphone jack?

Sound is working for me.

Not the Sound CP, but QuickTime movies and Audion playing MP3 - via the audio out jack. Awesome ! I haven't seen how games will play as yet, but if a game depends on QT, then I would think it's not going to be an issue. Sound level software sliders in QT and Audion also working very nice.

One thing that I tried, which may or may not be a factor. I read elsewhere that folks running Mac OS 9.1, upgrading the firmware on the G4 Cube (The Apple System Profiler think the mini is a Cube) audio stopped working. Their workaround without upgrading the OS was to grab the Apple Audio Extension from a Mac OS 9.2.1 install CD and use that version's Extension and sound worked again.

Well that's what I've done... whether that was the magical fix, I don't know, but if sound isn't working for you, then you might want to try it, too.

OK the Sound CP still isn't working so I can't get System beeps when errors occur, but I think I can live with this.

My old eMac is looking nervous Wink

Just recently I acquired two Minis, mainly because I heard the word that OS9 is booting the Mac Mini G4.
Mixed results. The old 1.25 GHz Mini is working as advertized with sound output from the headphone jack.
The newer Mini, 1.5GHz with a revised inner carrier, is not playing sound - or its playing near or beneath my hearing limit.
Maybe someone is willing to explore how the fixed level output for the hacked OS 9 is set?

This is a known problem

Sound ? Yes, as I've discovered. I've tried all of the known options but it simply does not work for me (I don't have bluetooth speakers to try tho').

I have a FireWire external drive enclosure, which I've since installed this OS onto, and so far everything I need to have working other than sound, is working 100%

But a lack of sound is a setback for me, as I was hoping I could at last retire my G4 eMac once and for all Wink

Although not perfect, if you replace the Finder with the German equivalent, it gets you most of the way there.

This is a known problem and probably the greatest drawback of the this version of Mac OS 9.2.2. I get around it by connecting a simple audio cable from the headphones socket into a bluetooth speaker and amplify that way. There is sound but the quality often varies.

Another warning: I replaced the hard drive with an 2.5" IDE-mSATA adaptor. It was much, much faster than the 4,800rpm drive but I also lost the ability to use the optical drive. It didn't even register. It was as if the IDE-adaptor identified as either both master & slave or just as slave. If you have an external FW-optical drive, it may be enough.

Bear in mind also the the USB drives are max. USB 1.1. They are not fast. FireWire is the way to go or the 10/100 Ethernet.

Also, connectivity with monitors over DVI is hit-and-miss. Using the VGA adapter always works for me, not so with DVI.

Hard to find the proper adjectives for non native speakers/writers. Wink

Did anybody try the V7 to V9 upgrades so far and could give a hint what kind of files are accepted by the upgrader?
img, dmg or something more exotic, are localized OS9 versions in scope?

Hilarious, perhaps because SteveJobs announced OS9 had died, the rest of us say rumors of its death had been exaggerated?
