This is still off topic in a thread about unsupported hardware.
No one is trying to use teh internet on Jaguar.

Jaguar on newer 'unsupported' hardware

well smoke me a kipper ill be dammed
after Digging out my 14 inch iBook G4 today to finally get round to unbricking and pleasantly discovering that the above 12 inch iBook was hiding a 14 inch keyboard I duly installed it into my aforementioned 14 inch iBook G4 which has not had a working keyboard since I got it (I have always used it with a USB keyboard which has made it quite cumbersome to use at times)
I decided to play around with it some
and just for giggles I tried the above patches
(along with a couple others in OF to masquerade the system as a Firewire 400 (so MacRISC2) PowerMac3,6, so 10.1.5 knew which platform expert to use)
and what do you know it only bloody works
View attachment 1806946
really did not expect that given that the same did not work for my 867Mhz TiBook which is an Older system then the iBook G4
the only thing I can think there is if its some sort of dual display thing, since the TiBook supports spanning where as the iBook G4 only does mirroring, so have to wonder if thats playing a roll here
(at least normally, of course the iBook G4's hardware supports spanning just fine its just an OpenFirmware flag that disables it hence screen spanning doctor)
currently the TiBook with the necessary NDRV transplant and plist editing it will try and load the window server but it falls over something and only gets as far as a mouse which sometimes turns into a spinning Magneto-optical disc
will have to see if I can do a reverse of screen spanning doctor on the TiBook and see if that gets it booting on 10.1.5
(or apply the screen spanning patches to the iBook and see if that stops things from booting)
goes without saying since I got my iBook G4 PowerBook6,5 booting 10.1.5 it can also boot 10.2.8! tho this is something I have done before, and in fact, 10.2.8 more or less works out OOB just with no proper detection for the 7447A of course
so it would probably work even better on a PowerBook6,3 which has a 7445, which is a CPU that has native Jag support (which I see has been done according to the OP
)it is worth noting that stock I find sometimes Jag will hang on graphics/window server initialisation, but borrowing the 10.3.9 NDRV seems to have solved that issue
(graphics acceleration itself works OOB )

I thought there was a thread for this but I mixed it up with “The Jaguar Thread”. Shoulda posted my eMac results here.. oh well🤷🏼♂️
indeed I did think that!, hence one of the reasons I posted the above, to give it a bump back up the to the top
ill quote over all the recent Jag on newer hardware posts from that thread to here, so everything is one place for easy reference
(on getting graphics acceleration working on the Mac Mini G4 in Jag I think that will require some hex editing of the Driver binary itself as I think the Device ID has to be in both the plist and the Binary itself)
that will likely be an NDRV issue
and you "just" need to move the NDRV over from a supported version of OS X to 10.2.8 and hope it works
like what I did to boot 10.1.5 on my 800Mhz iBook G3, PowerBook4,3
The Puma Thread (Mac OS X 10.1)
Got 10.1.5 booting on the 800Mhz iBook G3 :) , got it booting after I transplanted (and renamed) the ATI NDRV file from 10.2.8 into 10.1.5's AppleNDRV Folder and added ATY,Bee to the plist file (in 10.2.8 the NDRV file is in a bundle in the NDRV folder and is called ATIDriver but in 10.1.5 its...forums.macrumors.com
very pleased to see it worked
this should also in theory also get 10.2.8 Working with the Mac Mini's Radeon 9200, ill give that a bash tomorrow me thinks
now we just need someone to compile a 10.2.8 kernel that recognises the 7447A properly
(note that it does not say PowerPC G4, 10.2.8 non G5 build was the last version of OS X to run on unknown CPU's and ran in a generic PowerPC mode, so G4 specific applications may not run FYI)
I think it should in theory be possible by re-using the 7447 code and just tweaking the PVR value from 8002 to 8003 where necessary and maybe looking at 10.3.5+'s source code if needed
(and while at that also doing the same for the 970FX so we can boot 10.2.8 on a 2.7Ghz G5
yep worked just as I thought

I dont think Graphics acceleration is quite working yet 5962 is not a device ID in Jags Radeon 9200 driver and even when added although I see the kext loading in verbose mode I still get tearing when dragging a window around and I dont see any of the acceleration bundles loaded when I check in ioreg
but im pleased to have at least gotten the low level stuff like resolution changing etc working
sound will involve playing with kexts and plist files I imagine
NDRV's is generally a video/graphics specific thing
It's best to use the kexts from a full OS X installation since the OS X that boots from the restore disc is pretty barebones, and to replace them in OS X just to be sure, as well as fix ownership (root:wheel) and permissions (755) after replacing them (in OS X) - if these got mangled the kexts won't load. Also try loading them manually with sudo kextload /path/to/whatever.kext in Terminal and check what it says in the system.log. Maybe the newer kexts depend on something that just isn't there on 10.2.8, or require other (newer) kexts as dependencies.

Yep just as I thought I had peak inside the Binary itself and the same device ID's that where present in the Kext's plist file where there, so I took the device ID for the Radeon 9200 that is present in the 10.2.8 kexts, 5961 and changed it to 5962 the device ID of the Mac Mini's Radeon 9200, in both the plist file and the binary itself
and Bingo lovely smooth Graphics acceleration along with the previously enabled fully working frame-buffer by way of NDRV transplant as per above
no more window/screen tearing and I can see the Acceleration bundles are loaded in ioreg I am very pleased to see this worked as I thought, as It opens the possibility enabling graphics acceleration for other such unsupported hardware and software combinations

This is great news. I can’t wait to try this out after my work stretch this week.Yep just as I thought I had peak inside the Binary itself and the same device ID's that where present in the Kext's plist file where there, so I took the device ID for the Radeon 9200 that is present in the 10.2.8 kexts, 5961 and changed it to 5962 the device ID of the Mac Mini's Radeon 9200, in both the plist file and the binary itself

I wonder if it would be possible to get my G5’s Geforce 6800 Ultra to work…
sadly the 6800 Ultra requires an entirely different set of drivers
its an NV40 based card (in fact the original NV40 card!
)10.2.8 only has drivers up to NV30 based NVDIA cards sadly
I kinda figured because of the KP I get when trying to boot it.sadly the 6800 Ultra requires an entirely different set of drivers

Oh well.
How did you get this to boot? I have the same Dual 2Ghz Power Mac G5 model and tried booting from this G5 10.2.7 disk. It booted but said that the computer was incompatible. (Also fans ramped up to 100% as expected)The newest hardware I've had Jaguar running on is a Power Mac G5 7,2 (dual-processor 2.0 GHz). Mine was manufactured in 2004 based on the serial number (meaning it shipped with 10.3 Panther originally) and is unsupported by the retail / normal version of Jaguar, but works fine with the special G5 build that only came on gray restore disks.
As far as I know none of the newer / more powerful G5s will run it, so this is as good as it gets for Jaguar with the classic pinstriped Aqua look.
I see you are on 10.2.8. Did you use the same disk or another one?
Patch the installer to remove the model identifier check.
