Thanks. I was just puzzled by your notion about it being "completely pointless" :-)

Well then, to make it clear to anyone who might be wondering about the boot menu question... You don't need a boot menu to run MorphOS on a PCIE G5 machine with an R500 graphics card with its original (x86) flash. Thus modifying the flash on an R500 graphics card would be pointless for running MorphOS.

AND the Apple X1900GT is available which gives us an R500 based card capable of displaying Open firmware prompts.
I have one, but would probably use a PC X1950XTX instead.

If you want more power than the X1900GT you have to give up easy access to Open firmware, so I'll keep the X1900GT as a backup if I need to do that, and move up the ladder as our remarkable developers improve the drivers for the HD Radeon cards.

Oh, and a quick note, I have not found Mac Radeons to be hard to find at all.
9600 cards are everywhere at really low prices, 9800 cards are over priced but available, X800XT cards can often be had at better prices than the 9800s, and X1900GT cards can be had for about $100.

The simples solution is not dual video card? Original Apple card for OpenFirmware and Osx, and another card (normal RadeonHD pc card) for Morphos. With two monitors or switch.

P.s. second video card is also good for linux

That would depend on how MorphOS initiates video cards, as MorphOS can only use one Radeon card.
If the card you want to run OSX or Linux with initializes before the card you want to run MorphOS on, your solution won't work.

I have a PCIe riser with a molex power plug that I may modify for this use.
Add a switch to turn off the power, no card is seen and the OS will boot off the PC card.

You can swap the radeonhd on pcie 16x and original Apple Nvidia on 8x, linux go without problems with RadeonHD.

Look this tread:

Ubuntu Forum

Edit: the best for compatibility is use RadeonHd on 8x pcie

Which Powermac?

Quote:

That would work, Radeon PC card for MorphOS and Nvidia Apple card for OSX.
If you connected both to the same monitor you could probably limit your system to one display without using a VGA or DVI switch.

Splendid :-)

(original resolution)

Now that is a good photo (at least the resolution is pretty damned good).
But I can't pinpoint anything that would ID the system the OS is running on.

I can't see the picture.

TRy right mouse key and download picture as file.

Don't work.

Quote:

Yes I can confirm that we have it on AmiParty.
Rzookol show it . And system run nice and very fast .

ok, it seems that there was only one lame photo of my pmac g5 on this meeting so:

g5pcie.png

BTW. G5 PCIe port is highly experimental and for 99% won't be available in MorphOS 3.10 (3.11, 3.12, ...) because more important things have higher priority.

Quote:

It is a shame

Quote:

OK, that definitely IS a PCIe G5.
But what things would have higher priority?

Quote:

Probably polishing up the work done to make MorphOS boot on the X5000 and/or 3D support for some of the RadeonHD video cards.

If not those two reasons, then perhaps they are closer to having an x64 release and want to complete a first version of that, instead of spending more time on the last unsupported G5 PowerMac models.

Unless I missed some news recently, the video card support for RadeonHD to be used in the X5000 is/was not up to the usual release standards of the MorphOS Dev. Team, so it would make sense to me that they improve that area with a higher priority than supporting the PCIe G5 PowerMac models.

OK, I can understand the argument in placing priority on the Radeon HD video card drivers.
We already have a very good R500 driver, but why limit us to the X1950XTX as our best performing video card?

I think the projects is related, x5000 (pcie) and radeonhd is the same goal for G5 pcie work.

Well, it can be like with the iMac G5 port not happening: some crucial parts are not working properly and thus the port is on ice. Until the Team says that a PowerMac 11.2 port is on it's way it might as well not exist at all for all we care.
