Don't try this at home...

Well it does see both the MorphOS CD and the SSD I had prepared on the AGP G5, it does boot them, but no display an any port of the R5 230. Actually not 100% sure if the SSD booted, but it did show up in the startup menu.

Hope the HD4670 will fare better.


@matt3

Good to know it would work that way if I get a 2.5GHz CPU, but what ThePlayer suggest is using 1 CPU in a dual socket Quad mainboard which might a different set of dice.

Up to installing 10.5 to make sure those SATA ports work for sure.

That one should work (#41). Don't know about the others.

The 2nd CPU is allegedly (#35) turned off automatically by MorphOS since 3.10.

@ Kronos - Just for info - the Airport Extreme A1027 works in the PCIe versions of Power Mac G5s (A1117/A1177 models).

I have this installed in my PowerMac DC 2.0 GHz system, though I haven't got the system running, but it is recognised in Mac OSX Leopard, just be careful which way you orient the card. I seem to remember it needs to be with the "Airport Extreme" wording facing upwards. There is no metal "keyed" slot to enforce correct alignment over the Airport/WiFi connector, as there is in the earlier PCI Power Mac G5 models, that is why you have to be sure you have it oriented correctly.

Most users try to find the "RUNWAY" card, which also plugs into that slot, but also allows (I believe) you to mount the Apple Bluetooth hardware on it as well as the Airport Extreme card (A1027), but as the "RUNWAY" card is as rare as "hens teeth" and sells for "silly" money I haven't bothered trying to acquire one, as I don't need it.

Also, if you want to use some Bluetooth keyboard (Apple A1016) or other Bluetooth hardware then if you have a dual-boot system then most of the mini-Bluetooth dongles available via internet online sales will give you Bluetooth capability if plugged into a USB socket on the PowerMac. Ideally they need to be compatible with Windows XP as those are the ones I have found to function correctly on Mac OSX Tiger/Leopard.

Hope this info is useful.

It's also worth noting that when placed incorrectly, the Airport Extreme card will stop your G5 from booting at all. So if you've just mounted A1027 and the machine won't even start (no reaction to power button) - you know where to look.

(this statement has been personally verified on no less than two Power Mac G5's to the unspeakable personal horror and then - relief of the one writing these words).

Well I did get 10.5 installed so SATA does work (it was sold as non booting with a HDD installed).
Only saw 512MB which I fixed by swapping places for the Apple 256MB and aftermarket 1GB modules. Corrosion? Badly seated? Dunno seems to work.

Got a new (NOS?) NIC coming in at 9.99€ which should work.

Quick google suggests that the A1027 can be found in (non US) PowerBooks so I might dig through my pile of spare parts, but not a priority.

Kinda unrelated side note:

Putting in a RadeonHD from a MacPro will make the G5 fans spin hard, it will boot, but MorphOS still won't use the card.
Not that I expected anything more ;)

Quote:

Early PowerBooks G4 and most iBooks G4 used A1027 cards for WiFi.

Alas, you will also need an antenna that fits (as the internal antenna connector won't work without some kind of adapter). The connector needed for A1027 is MCX male AFAIR and the internal antenna connector is U.FL (needs double-checking).

Well quick rumble through the heap only showed 1 card installed in a 5.8 which only misses the upper case/display that I might want to recover at some time.
Thats not "early" so, no idea if it would fit at all.

Oldest one would be a 5.5 but thats in parts and I haven't found that module yet.

Antenna should be no problem as I have at least 2 broken 17" displays where I could pull them out.

5.8 is using an AirPort/Bluetooth combo card (AKA A1127) - the same the Mac Mini is using. Sadly, to use this one in a PCIe G5 you'd need a runway card to fit it into the slot.

I believe 5,5 (A1085) also utilized the same model. For A1027 you'd have to go back to something 2003 or earlier.

In the 15-inch models you'd need to open the battery compartment. The Airport Extreme card should sit there behind a tiny flap (as seen here).

In the 17-inch models you'd need to look inside (and I mean inside) as the said card sits beneath the PCMCIA cage. If there are no white "Airport Extreme" letters visible through the cage - it's not worth the effort to dismantle it.

Well so I don't have any of those.

Just for fun I bid 1€ on ebay (+1.1€ shipping).

Pricey stuff.....

@ Kronos & koszer - the Airport Extreme cards in the earlier Aluminium PowerBook 17 inch versions have a membrane connector in any case, which is incompatible with the mini-PCI type connector slot in the PowerMac G5 PCIe models or even the other PowerMac G5 PCI models. So, only consider buying the Airport Extreme cards with a mini-PCI double-sided type edge connector.

That said, I am sure I have a spare Airport Extreme A1027 card of the type that would fit that I could let you have for 10 Euros, plus shipping costs (thin small padded envelope postage) to where you are, if that's the way you want to go with WiFi in your PwrMac G5 PCIe. The card cost me at least that amount so I would not be making any profit from letting you have it you are unsuccessful in your bid on the card you're interested in acquiring. Just PM me if your interested in buying it.

The one I bid on does look like it would fit into the slot, so I guess it is the right one.
I typed in 5.55€ and I don't plan to increase the bid since it is more of a gag than something I would really use daily.

Hmm i would try to remove one of the 2,5 dual Core CPUs. It should be the lower as the 2,3 has the upper installed. And then put the Air cooler from the 2,3 on the 2,5 CPU and hope it will work.
Do i need the ADC CD or how this tool is called to calibrate the fans? I remember i had to do this with my old 2,7 G5 after moving from water to air cooling.
