No. But on a 7,3 you'll be using APM anyway as it can't boot from GUID.
Well yeah, I'm more worried Jag won't be able to see the disk. GUID was needed for the size, and as far as I know, made it useless to boot off of even for Leopard on PPC. I don't know when they actually added support. It's not a boot disk in the system for me, it's actually the drive I do all my file serving on my network from. So maybe this system isn't the most friendly to testing like this.

Still, I need my answer. And if it works? Well, I can do a little bit of benchmarking in Jag's classic, and compare it to everything else I have on hand.

It's probably safer to not have Jag touch the disk/its contents because it's larger than 2TB, and run it off the CF card instead. Late 2005 G5s can actually boot from GUID.

There's a reason I boot off a 500gb drive on this system, but this fact is a bit trickier, since the 7,3 is either a mid 2004 or early 2005. Not to mention, there's conflicting info about this stuff all over the place. I did have to go into Leopard just to format the drive, in the first place, Tiger was very confused by it.

Still, I have a plan, and I can make myself a setup disk before I can get the free time needed to really test this whole thing out. It's just a shame the official 10.2 disks for G5 were only a stopgap, I wouldn't need to do this.
 
The G5 10.2.7 install disk does boot enough to tell me my 7,3 isn't supported, in a very vague way of course. But, all the way to the installer, and everything. And if it boots enough to tell me off through an installer, than who knows?

I'm going to have to put some time into this, it sounds worth doing. For all I know, I could be opening a whole new world of PMG5 support. Or a nightmare for anyone who follows in my footsteps. :D

God though, a PMG5 Hackintosh. I love it.

its really easy to get round that, just change PowerMac7,3 to PowerMac7,2 in the root of the Openfirmware device tree

boot into OF and do the following


Code:
dev /

.properties


" PowerMac7,2" encode-string " model" property


" PowerMac7,2" encode-string " MacRISC4" encode-string encode+ " Power Macintosh" encode-string encode+ " compatible" property


.properties

(NB this is volatile and not permanent and is lost across reboot but you should only need it to boot the CD, the .properties is so you can view and take a picture if needed, of before and after and make sure all that changed is PowerMac7,3 to PowerMac7,2)


although its interesting that you say it will boot in my testing 10.2.7/10.2.8 G5 wont boot on a 970FX CPU as it was first kernel versions to introduce the "halt on unknown cpu" check

if you want to confirm what CPU you have, install CHUD Tools, and then install the processor preference pane or open up ReggieSE, it will tell you :)

10.0 and 10.1 keep failing installs so I gotta figure that out, but the other two work perfectly.
What exactly is going wrong with them?

For 10.0, you could try this disc - it's a newer build than the downloadable 10.0.4 updater:


For 10.1, I can hook you up with the 10.1.5 disc for the original 17" iMac which is also a newer build than the downloadable updater. Or just use Puma Server for the Xserve, which is the newest 10.1.5 build out there afaik.

They both got about 5 minutes in and failed with an error that said something along the lines of “couldn’t unarchive packages”. I’m was going to try again with the newer 10.0.3 and 10.1.3 CDs.
Edit:
Didn’t work. I used a different Mac as well as the 10.0.3 installer and it still fails in the same place.

Oh, I guess I misunderstood what the problem was then. I thought Project Alice couldn't find it. Sorry!
I couldn’t find a single DVD Panther image. The retail discs are everywhere. I did find the 10.3.7 image mentioned though. I probably won’t be able to use it for this because it’s almost 8GB and I only made a 5GB partition for the installer.
 
We have ourselves a PowerPC G5 (3.0) which means this is going to be quite the experiment. If it works, I'll be opening a door, otherwise, I'll be sure it was never open at all. Either way, I'll finally have an answer to a particular question I had, ever since I ran into that unsupported system message in the 10.2 installer.
Any news on that front? :)

Is it possible that the kernel on the 10.2.7 g5 install dvd doesn't have this check for some reason?
 
@Amethyst1 @LightBulbFun Unfortunately, life got in the way of the things I wanted to try. Tossed the G5 Jag disk I had burned into my dual 2.0 GHz 970FX just to see what kind of error message I'd get, and it's not what I remembered, that's for sure.

And I'm guessing a glitched out Apple logo means I need to reburn that disk. Really wish I had more, but Jaguar hasn't been my number one priority, and things keep pushing it down on the list, but I promise, I will get to it.
 
Can someone explain to me why bother with 10.2 if nothing really can run on it ? i DON'T mean to be rude, just that nothing will run on it - can't use internet at all directly with anything under 10.4.11.

That is just plain wrong. And you've asked this same question multiple times already and received answers.


And just for the record: to me, the usefulness of an OS does not solely depend on the ability to browse the stupid web on it.
