Snow Leopard on Unsupported PowerPC Macs

Status
The first post of this thread is a WikiPost and can be edited by anyone with the appropiate permissions. Your edits will be public.
No QE or CI, but it boots just fine on my A1095 (Powerbook5,4), using the image that @Larsvonhier supplied. Doesn't seem to want to sleep either. Time to put an Airport card back in it and see if it works.

Hey peeps - just caught up on the last 3 pages of the threads.... great to see all the progress! Some updates from my digging, which hope are useful:

Managed to re-download 10a190 and 10a222 properly this time.

Kexts
Have managed to compared which kexts have been removed in each build since 10a96 - as working on the assumption that PPC stuff would be being stripped rather than actively patched or added up:

Between 10a96 and 10a190:

Tools
It's great to see people using Pacifist and BatchMOD - as well as deleting the extensions cache files - this brings back old memories of using these to do 10.5 on G4 upgraded PMs....

Also great to see that terminal command to dig deep on the reporting architectures of all libraries and files in the installs.
This will really help fine-tune the merging of all the components likely needed to achieve what I reckon will be the final mish-mash SL PPC build we'll end up with (maybe a mishmash of all of them up util the point PPC was properly stripped).

Finder
The 10a222 Finder build seems to be non PPC:
finder: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [i386]
finder (for architecture x86_64): Mach-O 64-bit executable x86_64
finder (for architecture i386): Mach-O executable i386

However the 10a190 build still includes PPC:
finder: Mach-O universal binary with 3 architectures: [x86_64:Mach-O 64-bit executable x86_64] [ppc_7400]
finder (for architecture x86_64): Mach-O 64-bit executable x86_64
finder (for architecture i386): Mach-O executable i386
finder (for architecture ppc7400): Mach-O executable ppc_7400

Request
May I make a special request? I'd love to complete the legacy of the 10.5 on PowerMac 8500/Beige G3 work by getting a SL 10.6 image to boot on one of these computers. I still have them - but they are not setup and i've got quite a busy life with 3 kids, work, etc right now. Would anyone mind holding off testing or getting this to work on this super-early hardware so I could complete that legacy myself, as a specific piece of work to add to this otherwise very collaborative effort? What do @Larsvonhier @Project Alice @B S Magnet think?

No problem for me, as my currently oldest hw is a blue/white G3 that has to be updated with firmware for the G4, and a very odd S900 pulsar that never had Leopard running, only Tiger.
As that one is close to your 8500, I‘m eager to see your results on it when you have progressed that far!

I mean, I don’t have a stake in old hardware, as my only gear older/slower than the DLSDs (both of them) is the clamshell FW SE, and I wasn’t remotely thinking about it for even early known builds of Leopard capable of booting in a G3. So have at it!

Also, I’m not really on the forefront of all the latest testing/experimenting due a combination of time, technical know-how, and also the need to take apart my 15" DLSD to re-do the thermal paste, as the video card keeps overheating and turning the screen dark, dark grey and forcing me to leave everything turned off for a good while (and yes, the G4 fan control kexts are in place, but this has still been a recurring problem since the 10.6 install).

Though CI/QE is not available (yet), I found that when adding the Radeon 9700 kexts and enabling QuartzGL, the system is much more responsive. Dragging windows is sill done by software, but the felt framerate is higher (not smooth, but usable).

Hi,
I also have 2x 15" DLSDs and haven't replaced the thermal paste until now. I also do own the predecessor (A1106, 1.67 GHz) which I freshly repasted a couple of weeks ago. The DLSD and the A1106 don't show considerable temperature differences surprisingly but then again I haven't found a way to read the GPU temperature (only CPU, trackpad and HDD). What application do you use for getting the GPU temp? Is there even any? Do you think the fact that your DLSD is overheating has to do with Snow Leopard primarily (meaning that it is somehow overstressing the video chip – maybe due to lack of graphics acceleration) ? I really want to try Snow Leopard on my DLSD(s) but do not want to kill it/them by doing so. I'll rather try the Snow Leopard preinstalled dmg on my recently repasted A1106 and see how it performs and maybe play around with some kexts (if necessary). Anyways, this is a great thread and I've never thought that we get to see another OS X version running on PowerPC after 10.5. I can do some testing on my iMac G5 iSight and iBook G4 (Mid 2005), I don't think we have test results of any of those machines yet.

I don’t yet know why it’s overheating, except to note how I’ve used this DLSD a fraction the amount I have with the 17", which I sometimes use as a daily driver.

It’s possible I did try to re-paste the heatsinks back when I got it, but I can’t conclusively remember if I did or not (though I have clear memory of doing so with the 17" model). If so, then I’ll need to do a better job this time.

The 15" was found as DOA on ebay for, like, $25 plus shipping, and I was able to revive it. That said, it has some troublesome aspects which suggest a harder reliability life versus the 17" (which similarly was found on ebay for a dirt-low price, but the seller didn’t know about which install disc to use, thus kernel panics for them).

For example, the 15" logic board is a replacement, and the solder points for the integrated Airport/Bluetooth bus are faulty somewhere on the board itself (despite using two different flat cables and two different cards with the same boot kernel panic). It also lacked the PC Card button release cap and modem (which doesn’t bother me), so there may be other components on there which are no longer as robust as, say, my 17" (which seemed to be treated more gently).

I use iStat menus for both DLSDs (and for all my computers). The peculiarity with the 17" is, when idle, the GPU reports as “100°C” which is clearly inaccurate. When any load gets placed on it, the temperature then falls to something like 54°C and then upward slightly as usage demands increase, returning to “100°C” when idling. With the 15", same GPU, it doesn’t really do that, but by the same token, I’ve never really put it through a lot of usage stress prior to testing the SL 10A96 build.

But no, I don’t think — not for now, at least — that SL is responsible for the possible GPU overheating, but that’s TBD as I take it apart and test it again after a re-pasting with Noctua NT-H2.

Less thermal paste is more cooling. So less is more in this case! And it is generally recommended to let the fresh paste spread under low-medium heat (processor and GPU loads) for at least a couple of hours before heating it up by demanding tasks!

Yes, I do know that, as I’ve re-pasted literally all of my other computers in the sig line, including the dual G5. My hypothesis is either a) I never actually did the re-paste on the 15", or b) I didn’t seat and tighten the fasteners to the heat sinks properly.

I’ll know soon enough.

I did enable QuartzGL, and it seems a little more responsive. Haven't added any kexts yet, but I'll do that later today. I'll probably add all of the tested and working kexts, as Airport doesn't work.
 
Hi Project,

So I've been through your logs.
I think I may have found something.

Can you copy from Leopard the:
NVDAResmanPPC.kext and NVDAResman.kext from Leopard and see if the Geforce kext
loads?


Best regards,
voidRunner

That caused a kernel panic on boot. I booted again to verbose, and it doesn't look related to those kexts, but I'll put them back anyways and see if it boots again.

Edit: After rebooting into Leopard, Leopard gave me a KP report even though it wasn't the OS that did it.

Hi Project,

Can you try something different.
Clean all Geforce related kexts from SL and put back the original ones
and see if it boots. ( Geforce.kext and NVDA* )
Also remove the Extensions.mkext file that might be causing problems.

Then see if Geforce kext has loaded ok.

Best regards,
voidRunner

Booted up okay after doing that, but now none of those kexts are loading at all.
Also, it doesn't have an extensions.mkext. Even after running the script initially it would also say file not found for rm /s/l/exentions.mkext
I still can't remove it because it says it doesn't exsist.

In 10A190, the extensions.mkext has moved to /S/L/Caches/.../Startup/ I think the ... is com.apple.kext.caches but you'll have check yourself.

Geforce.kext loads but that (as with the ATI9700.kext on other machines being loaded ok) does only improve things partially - no CI/QE in any case...
(the 6600 still being the sole exception)

Hi Lars,

Please send me your logs so I can look at them
and see if I can find something.
If the 6600 works than the 6800 as to work too ( it's the same kexts ).
ATIs is another matter as they never worked.

Hello, I have tried to install both the 10a190 client and 10a96 server versions on g5 dual 2.3 (power mac 11.2) and g5 quad 2.5 (powermac 11.2) both with the nvidia 6600 I have also tried it on an ibook g4 1.42 (powerbook 6 , 7) and I always get kernel panic.

Also download the 10.6 image (PPC_SL_10A190.dmg) already installed and clone it to the g5 with the disk utility and with the CCC both without success, always getting the message Restart macos x.

It should work on these machines, right?

If someone can give me any indication or suggestion.

Thank you
