This card won't work in a PPC Mac (at least unless reflashed), as you were told 4 years ago (#27 and #28).

I do have a PowerMac G5 7,3

It has only one AGPx8 Slot in which a Radeon 9600Pro currently works.

I do have a Radeon X800 GTO AGP (in an older PC)

Does it work with the G5 and MorphOS then ?

The readme states yes, but does it need MAC OS firmware ?

Or is it the same as with the PCIe cards, so that only OF does not work ?

Try it... normaly yes working.
And no need MAC firmware (same as G5 PCIe)
On my old G5 AGP, i have X1950Pro AGP (PC Version inside)

@Trekman

1st question would be if this card has "AtomBIOS", if yes than it should work for MorphOS (no OSX, no OF).

But....

AtomBIOS seems to be hit and miss in AGP G5s.

I run a HD3450 without issue while analogkid had no such luck with an almost identical card.
Might be 3.19b vs 3.18, might be the difference in the card or even something random.

So, maybe wait till 3.19 change cards and see if you get a picture.

Is it somehow possible to see if it has "AtomBios" ?


:-)

No, while R400-based "PC" cards do have AtomBIOS (it started with them, actually), it's a too old version of that to be supported by MorphOS, which only supports the AtomBIOS versions starting at R500-based cards. This is what the MorphOS graphics driver developer told as of MorphOS 3.15 (#6), and I doubt it has changed since then.

> does it need MAC OS firmware ?

Yes, it does.

> Or is it the same as with the PCIe cards, so that only OF does not work ?

No, you'd need an R500-based (or newer) AGP card for it to work this way.

> Is it somehow possible to see if it has "AtomBios" ?

Yes, but it won't be of help (see above) :-)

One quick addendum to my prior post.

The X1900 cards I bought were branded G5 PCIe cards from a seller on ebay. They were brand new, but I suspect the seller may have flashed them.

Chris Edwards bought the exact card as seen on his YT.

It is truly plug and play for MorphOS.

The most important item is that you can get into early startup for the PowerMac, and you can't with a PC card...

It's not impossible that support for old AtomBIOS of R400 generation has been added in 3.19, yes :-)

You can get into OpenFirmware and the boot menu if you do as suggested in comment #6 and leave the original Nvidia card in place and add the card with AtomBIOS as secondary card for MorphOS :-)

I tried the Radeon X800GTO AGP card and can confirm :

It does not work ! (at least with my 2GHz G5 PowerPC)

I do not get any picture !

Did you have MorphOS installed previously (before the gfx card swap) or are you trying to boot an AGP G5 Power Mac from CD using AtomBIOS card? Because the latter won't work.

EDIT: I just figured out X800 is not an AtomBIOS card, so you won't be able to boot anyway. You need a newer Radeon (or Apple BIOS for this card).

Probably right.

> X800 is not an AtomBIOS card

But it is, just too old version of AtomBIOS for MorphOS (see comment #21).

Back again

I bought a X1950 Pro Xtreme 512mb from ebay, dont know anything about AtomBIOS, but some suggested to leave the original card in the Mac.

Should i put the new X1950Pro in Slot 3 which is a X8 slot ? slot 2+4 is only X4

The Fan on the X1950Pro is huge and the Clear plastic side won't fit
so i need to find another Fan/cooling solotion for the X1950Pro.


and last which PCIe Lan sould i look for ?

Peter

You should always put the Radeon in "main" slot, so the x16 one is the way to go. If you want to leave nVidia inside - use some other one.

You can get rid of the plastic deflector - the airflow should be fine enough without it.
Just make sure to put a piece of paper inside the right bottom hole for the deflector (notice the deflector had a white sticker there), there's an optical sensor you need to fool. Otherwise the fans will blow at full speed when the machine realizes there's no deflector present.

Take a look at this thread. You'll find a list of tested and compatible cards for your machine.

you can t use x1950 pro pc if the memory is 512m
and you have to buy a sapphire for pci-express
i d'ont test another card but you can try

> you can t use x1950 pro pc if the memory is 512m

Radeon X1950 cards with 512 MiB have been reported (#8) to work fine with MorphOS, just that only 256 MiB are recognized (which is expected).

Hi again

thanks for all info, very appriciated


The X1950 Pro 512mb works fine with MOS. except the Fan is huge so the clear plastic side won't fit anymore, so i have find another Fan/cooling solution.

Had some problems with installing MOS (no drive found), but found out the G5 is a little picky with use of new SSD, so i took and old Sata HD and it worked fine.


Next is to source a Wifi card for the G5 Quad...

is Wifi stable on MOS ? or is LAN realtek 8168 the best solution ?

which solution should i go for ?

i would love to have the "original" combo WiFi card from apple and the runway card to plug in the Mobo so i don't take up the last PCIe port and use the builtin antenna..

but will it work with MOS ?

I do think it will be hard to find


What's the alternative ?

and PCIe card with Wifi (older Atheros) ?

what about a USB solution ? is't posible ?


Looking forward to get a snappy MOS machine with network


regards

Peter

SSD: possible... some SSD are incompatible with old PowerMac

WIFI on PowerMac... i think LAN realtek 8168 is better solution...


Quote:

the x1950 pro pc i have (sapphire) 256 mega works perfectly and the fan too.
i read in fact that some cards have this problem with the fan
perhaps a resistance can help i don't known

Or cut a hole in the plastic deflector, or get rid of it completely (as I wrote in another thread).

Quote:

Yes, it's SATA-I after all. There's been some clues that the "B" harddrve bay cable is more tolerant, but most SATA-III drives still won't work.

Quote:

As for WiFi - it mostly depends on your network. Still, the same hardware seems to work better with the same network setup on OSX, so... I'd recommend Realtek anytime.

Quote:

Sure it will.

Quote:

It will be 100% hard to find and pricey as hell.

Quote:

A1027 with external antenna (or some adapter from MCX male to whatever type late G5 internal is using) or Atheros 5000 chipset based PCIe card.

Quote:

Not likely.

Hi

thanks, i have just ordered a Realtek 8168 PCIe card.
so i can get online

WiFi can come later....

hmm

i ordered a nic card (gimbird with realtek 8168b) but the shop sent me a :

Gembird NIC-GX1 with Realtek 8111C

is there any chance it will work with MorphOS ?

regards

Peter

I am thinking about adding a SATA SSD into "B" slot in my G5 PPC. So does someone know which

manufacturer works ? And which SATA should it be ? (SATA I / II / III) ?

It needs only to be a 128GB drive or so.

Anyone ?
