Will this piece work for MOS 3.2?

Pro's & Con's?

PCI-E Powermacs won't work with 3.2

Seems to be the model in the middle on the webpage linked to therein.

@zukow

There were only 2 PMacs running at 2.5GHz.

- a dual with AGP and PCI-X, this one was the very first model to use liquid cooling ->leaking guaranteed

- the quad with PCI-E, the last topmodel of the G5s, clearly not supported

The Dual processor (PCI-X) one will work, the dual core (PCIe) one won't.

As far as I can tell.

@stephen_robinson

There is no such thing as a DualCore PMac running at 2.5GHz (well unless you'd nick the 2nd CPU from a Quad).

You is correct, in which case, looks like a good G5 then.

Baring in mind 3.2 not out yet, and you'd have to be mad (like myself) to buy a computer before it's released.

Any idea on 3.2 release?
I miss Neverball.

Sometime between now and the heat death of the universe.

PCI-e models might be supported in the future.
But what video cards would work?
I don't know of any Mac compatible ATI PCIe video cards.

Then you must have forgot about it ;-)

I didn't forget it Andreas.
I haven't been able to find PPC compatible roms for the X1900.
The X600 was used onboard in the G5 iMac, but not as a card in other systems.

I'm having trouble finding any ATI based PCIe cards that will work in later G5s (plenty of Nvidia cards).

Note - check these listings

http://themacelite.wikidot.com/wikidownloads2

Only Intel based roms

Maybe we can modify AGP roms for the R400 to support PCIe (the problem with that being the different interface and slightly different R400 cores).

Or drivers could be created that support non Apple cards (the drivers we created for ET4000 cards used in PT68K computers in the 80's didn't use the video bios, so I assume it could be done).

Since Frank has previously stated that he had the X600 in an iMac working, he must have some kind of beta driver.

And now that he is working on a SAM460 port, PCIe support will be something the team has experience with.

@Jim

Some "facts":

- first screenshots of MorphOS running on an iMac appeared shortly after those for the PowerMac G5

- http://geit.de/deu_geitmeeting10062011.html on the 3rd picture you see my unit .... not running MorphOS, but that was changed the next day (only for about 30min and noone bother to make a picture), GFX seemed to working on the same level as shown by Bigfoot in BadBramstedt half a year earlier.

So it seems that atleast from a 2D point of view the X600 is quite similar to the 9600/700 used in PowerBooks or PowerMacs.

Wether thats also true for 3D *shrug*
Wether that holds any water for chips beyond the X800 or PCIe *shrug*
Wether anybody in the team is interested in working on the iMac port or starting one for the PCIe PMacs *supershrug*

Maybe Frank could be talked into it.
After all, it would give us smaller profile systems then the Power macs

Then I'm wondering why you said you didn't "know of any Mac compatible ATI PCIe video cards" when in fact you do know of them.

You don't need to find ROM files when you can find genuine Mac cards, do you? :-)

> The X600 was used onboard in the G5 iMac, but not as a card in other systems.

The X600 isn't mentioned in any of the 2 postings I linked to.

eBay lists at least 5 offers on G5-compatible X1900 PCIe cards right now.

> Or drivers could be created that support non Apple cards

Even if that was possible you'd have to say goodbye to OpenFirmware then.

> Frank has previously stated that he had the X800 in an iMac working

X800 in an iMac?

>X800 in an iMac?

typo - X600

And there do appear to be PPC X1900s, since people are selling them.

Also, since we've exchanged message with people claiming to be using X1900s in G5s I can't question their availability.

So why aren't there available rom files?

"Pulled from a working G5 MacPro unit! Guaranteed to work! 14 day money back guarantee! Happy biddings! :)"

Enough said on that then.

But I'd still prefer drivers that don't rely on card roms.

That way we could do something more modern.


[ Edited by Jim 15.04.2013 - 00:25 ]

Of course, we'd still need R500 drivers.

OK Guys!
Stop beating me up about this.

The fact is the we probably will see support for this combination eventually.

Although, personally, I'd prefer an HD4650 or higher.

I've never seen one with more than 256MB of ram, and that's a XT not GT so that might be worth paying a bit more for. heck, if I didn't already have a 256MB 1900 I'd be temped myself!

edited to add, hang on, tThat is Intel macs only, the G5s have to use the 256MB X1900 GT model.

Now that you mention it, Andreas can probably dig up a comment where I mention the G5 compatible X1900 as being a GT (with 256MB of vram).

Well, I've just wasted half an hour I should be bed trying to re-find this website

http://www.jcsenterprises.com/Japamacs_Page/Blog/71BBF3EF-9713-4C53-8B80-26771F8A4087.html

And now I found it, it's not half as informative as I remember it being... Oh well..

"Radeon X1950 flashed WinPC"

Hmm...what rom would you use to flash this?

Would you have to use a modified version of the X1900 rom?
What about the reduced number of pixel shaders and ROPS in the GT?

I already did in posting #11 :-)

Good thing I have you here Andreas, as it limits my premature senility driven attempts to re-investigate topics I've already researched.

Still looking for an X1950 rom for G5 use.
Haven't found one yet.
