Hi.

I'm currently operating a PowerMac7,3 and it's working well.
However, I have 2 PM11,2 sitting here as well and as I recall there was some work being done for supporting 11,2?
What's the state there?


Cheers,
Manfred

They are pretty much supported.

You need:

- a Radeon GFX card, either a genuine Apple one (rare) or a PC card with AtomBIOS (X1?00, HD???? see list on morphos-team.net
With a PC card you want to keep the Apple NVIDIA card in the system.

- A NIC, RTL8168 is the common solution

You get (compare to an older G5 at the same clock):

- little more performance
- a little less power consumption


You can go all in and install 1 CPU from a Quad into a 2.0 or 2.3 model which will not only give you 2.5GHz but also the 1.25GHz system clock of the Quad without the insane noise and heat of a real one.

OK, cool.

I'll check out what's in those G5s (don't know exactly, one runs Linux the other MacOSX 10.5).

Is it just supported with MorphOS 3.19 and can/could I just swap the HDD (SDD) (theoretically if the gfx card works, they're both just 2Ghz versions.)?

If there is any supported Radeon present it should just boot.

Since you last asked 6 years ago right after the MorphOS 3.12 release, a least the following was improved:

"Devs/Audiomodes/I2s
- Disable internal amplifier if device is connected to HP/line out of PMac11,2/PMac12,1/iMacG5
- Control headphone mute based on plug status on PMac11,2 as well"
https://www.morphos-team.net/releasenotes/3.15

"Quark
- Fixed detection of some MacOF Bios R500/X19xx PCIe cards on PMac11,2 G5 machines"
https://www.morphos-team.net/releasenotes/3.18

> Is it just supported with MorphOS 3.19 [...]?

What do you mean?

Quote:
Yes, you don't need to do anything extra and all the "unofficial" support is there build-in, so swapping or cloning the HDD/SSD should work (except for the registration of course).

For the least amount of headaches, find a 1900 PPC Mac card.


PM 11,2 and MorphOS.


The 1117 single processor systems can be updated to a 2.5GHz processor:


2.5 update.

Excellent. At least someone has the overview. I asked pretty much the same question. :D

> 2.5 update.

Unfortunately, he keeps repeating his "G5 has SATA2 and SATA3 ports" nonsense, while in reality they are both SATA1 with one of them seemingly being more forward compatible than the other. Why doesn't he ask himself the question how a computer from 2005 should be able to support a standard published in 2009?
Also, opposed to what he tells in this video, there was never a 2.7 GHz PCIe-based G5.
And why is he running Elude's Dust demo directly on MorphOS yet he claims it's running through WHDLoad (thus UAE)?
Besides, to nitpick, the MorphOS demo mode is 30 minutes, not 20, and it's also slowing down in addition and not just showing the nag requester.

Seems this one has a NVIDIA A386 installed.
So I take it this is not supported and I need a card from the supported one at the link you posted?
I think I didn't get what you meant with "With a PC card you want to keep the Apple NVIDIA card in the system"?
You mean there would then be two gfx cards in there?

> 2.5 update

In that video he doesn't seem to have another NIC installed. Does the internal NIC not work?

There is a small card installed in the top slot.

Even if that is not a NIC he still has other options:

- just don't go online, no NIC needed
- USB-NIC, some actually do work
- Airport module, expensive and rare for the official G5 part, dirt cheap if you go full jank.

OK, just found this useful thread: https://morph.zone/modules/newbb_plus/viewtopic.php?forum=53&topic_id=13932
Looking for a gfx card. The X19xx cards seem really noisy, but I guess it doesn't really matter as the whole thing is noisy.

Regarding NIC, I mostly find RTL8169 or RTL8139 will they also work?

Quote:

Ah, sorry, forget the question. Seems RTL8139C is supported (on that page you linked).

Quote:

Sure, you would put the Radeon in the bottom slot as that is the fastest (x16) and the Nvidia 2 slots above.
What card? You can go to the list I linked before and select what kind of card you want.
Any PC X1300 or better should work.
If you want 3D support you should stay at X1950 or below as that is the limit both for the stuff on the ISO and the latest TinyGL beta.

Some of the HDxxxx and R5 cards do offer higher bandwidth and/or HDMI ports which might be a good choice if running high resolution is your goal.

I do run a R5 230 in my G5 at 3440x1440 which should work with public 3.19.
In the Mirari I run a X1900GT with 2x 2560x1440 something you might have trouble on 3.19 (but 2x 1920x1080 should work).

Bought a HD4350, but also a X1950 Pro, I'll check out both. Was quite cheep.

PCIe NIC with those chips are hard to find. But I just looked in the G5 and it might be that it has an AirPort Extreme module.
There is a grey thin card-like thingy above the RAM slots. Is that the AirPort card?


[ Edited by asrael22 10.10.2025 - 16:41 ]

Yep that should be airport.

Just install a GFX card, start MorphOS and checks wether it offers WLAN.

> R5 230 […] should work with public 3.19.

Half a year ago you wrote it showed "no display an any port" (#17) and "no display but the CD booted to the language/ kbd selector" (#36) and "did not work with 3.19" (#44) and "did not work at all with 3.19" (#104). Did you somehow get it to work with public 3.19 after that?

Well if we are pedantic I could point out that this another R5 230.

But I never checked that one with 3.10, so...

The 1st card was a bit of an oddball with 2GB, 2xDP and DVI which might have been the reason. Point is if he wants to go for higher res newer cards are the better option, older X1??? cards if 3D is what he wants.

> if we are pedantic I could point out that this another R5 230.

Thanks for clarification that this is about two different Radeon R5 230 cards where one doesn't work with MorphOS 3.19 and the other may work. Nothing pedantic about that.
An RV910-based R5 230 working with 3.19 on PCIe-based G5 Mac would be splendid news as highest so far reported working card has been RV810-based HD5450, while cards reported as non-working include RV910-based HD6450.

Well as usual I forgot that it's not an X1900GT, but a X1950GT.

Doesn't matter, both cards asrael22 bought should work (tm) and he will have to decide if he prefers 3D or a modern connector and less noise/heat as the 4350 should be fanless and come with HDMI.

Not sure right now what I would use the 3D for, supposedly mostly TinyGL based games?

I'll report back next week when cards arrived.
Thank you.

FYI

The 1900 and 1950 GT are quiet cards.

The 1950 XT is not, even when MorphOS spins the fan down it still is somewhat noticable.

Also, one clarifying item.

Even with a PC based 1900/1950 you can still boot from CD and install the OS. But be warned that Mac OS firmware might require a few reboots to get the PC card to "hook up" and start booting so MorphOS can take over. So still your best bet is the 1900 PPC variant. That is bullet proof and works without issues.

At the end of the day, the A1117 is still not officially supported, but a bunch of us use them as daily drivers and they work great... But you may run into issues with video cards because of this. There is only one video card that works as expected with this system. So keep all that in mind...

To get the PPC Mac to boot from CD first, you need to modify the firmware to boot from CD first and then you don't need the PPC Video card.

[ Edited by matt3 11.10.2025 - 09:31 ]

So seems the HD4350 doesn't work.

Could also be the card is defect. But no display on either port.
And there is a mechanical problem. The heat sink goes around the card to the bottom which doesn't make it fit on the x16 slot. So I had to put it to the x8 slot.
Something to keep in mind.
