Picked up two 2005 G5's for $80, untested with no power cords.

A little love with some wire, and I got one running, a G5 Quad.

The other DP 2.3Ghz powers on but makes no beeps or bongs, just sits awhile and the fans ramp up.

Not sure the trouble with that one, but I only wanted the quad;-)

Let me know if anyone needs parts for an '05 DP?

Congrats on the quad!

very nice find :)

I look forward to seeing what you manage to do with it

time for some linux QEMU KVM PPC Fun? :D

I got the Dual 2.3ghz working, bad video card and corrupted NVRAM.

Also @LightBulbFun I got OS 9 to boot to the NanoKernel in Qemu KVM-pr.

Hopefully we can one day get OS 9 to boot on a G5........

very nice work :) get a FireGL X3 for the DP2.3 and run Xenon OS? :D


sadly I have not been able to boot OS 9 at all in QEMU KVM on my PowerMac G5 even when using a G4 CPU option

I wonder if it would boot on a G4 Mac running QEMU-KVM but IIRC you have to recompile the linux kernel and disable SMP to get KVM working on G3/G4 CPUs for some reason...

I'm still trying to figure out how to run Linux on my PS3 Slim, I was thinking of an MMU side channel attack to load the kernel in memory and then jump there in real mode.:p

OS 9 does not load in KVM on a G4, I forget the reason, I debugged it a while back, I'll see if I can find the info I posted about it....

Install a custom firmware, it can patch and re-enable your OtherOS support. Even on a Slim :) .

Meanwhile a tech guy named René is working on GPU acceleration for that ps3 and maybe a more native boot solution.

Oh if you can grab a cheap (200$ ~) "PS3 TOOL" development console -> Sony have doubled the RAM. So do it ^^

I believe as long as you have the original card in, a second AMD card would work under linux. I would put in a RX560 and try out vulkan and 4K hevc decoding on that ancient harware. Would be fun...
I think it's only been tried with old TeraScale AMD cards.
If a cheap G5 Quad appears I'll probably get it, when I do I'll put my GTX 1060 in there and try to get it working under Linux.

Are the open source AMD drivers ported to LinuxPPC?

I know the nouveau drivers can init a PC nVidia card on Linux PPC, so any nVidia card supported by nouveau can be made to work with a powermac under linux, you just don't get any boot screens on that card.

I've successfully run Debian 10 on a G5 with a PC bios Radeon HD 2600 Pro.

Cool, if you could offer a howto or link that would be great?
I didn't have to manually load any modules or anything. I just installed the card, turned the machine on, and it worked. Of course, you won't see anything on the screen until it reaches the login manager, though.

Yes. They’re part of the kernel. The talos computer is a ppc64 and comes with a polaris card.

Not possible. Nvidia drivers are proprietary and only compiled for linux x86. The nouveau driver would be your only option but it provides abysmal performance and feature set.

Did you get anything in a console (Ctrl +Alt +F1), maybe with the AMD drivers installed?

I can't remember, as it's been a few months. I can give it another go this evening though. Is Debian PPC64 still broken? Which distribution should I install?

Sadly yes, as the ppc64 port is a sort of chicken and egg problem. It's too buggy, so people won't use it. But it's only buggy in the first place because there aren't enough people to test and bug report to make it not buggy so people will use it.

I'd try Ubuntu 16.04. Give the new USB flashing guide & premium desktop route a go while you're at it. ;)
