Hi,

I thought G5 quads were all PCI express - no AGP slot to fit the card in !

Don't forget to flash the ROM on the 7800 - you need access to a PC with an AGP slot and a PCI graphics card to drive the monitor so that you can see what you are doing. Full detail are in the above link, and they work well - I have done 3 of them so far.

If installing in a G5, details on how to get a Molex power feed to the card are here:

Easy to do in a G4.

Nick

Nick,

Thank you!

At MAC Elite their directions implied this would work in a G5. No, I did not know G5quad was all PCI! Wow, guess I better be more careful.

I have a five year old PC tower, and if I recall it has an AGP card in it already. I also recall that I have a new PCI card for that in a box somewhere.

I'll try putting that PCI card in it and get it to work with an old 15" LCD monitor. If that works OK then I'll pull the current AGP and substitute this 7800 one, then follow those directions.

I'll try to get that working first.

Thanks again,

eValuone.

You don't use ADC monitors do you? If so you will have to buy converters or special apple only video cards.

I am glad apple did away with that technology.

tLarkin,

No, we do not and as I recall haven't used ADC monitors.

G5quad was our first apple tower since about 2000. We used all laptops prior.

Thanks,

eValuone.

A couple of things I feel like I should probably clarify about that paragraph, just so everybody is on the same page.

There were five generations of Power Mac G5s (give or take, depending on how you count a generation). The first four generations of Power Mac G5 had one AGP slot (precisely, an 8x AGP Pro slot) for video cards, and three additional slots. These additional slots were either PCI-X (on the high-end machines in any generation), or PCI (on the low-end machines in any generation).

The last generation of Power Mac G5s, in which they introduced dual-core G5 processors, including the first "quad" machine with two dual-core processors for a total of four cores, used four PCI express slots (also known as PCIe slots, but completely different than PCI). The video card, of course, was PCIe as well. The last generation of Power Mac G5s did not have any AGP slot at all.

So, the first clarification is that those directions will work in a Power Mac G5, just not in any of the dual-core (including the "quad") Power Mac G5s.

The second clarification is that the last (dual-core) generation of Power Mac G5 machines did not use PCI, they used PCIe, or PCI express.

If putting "that PCI card in it" means putting a PCI card into the Power Mac G5 "quad", then that won't work. PCI does not equal PCIe. And a video card with Windows firmware will not work in Power Mac G5 until you reflash it with the appropriate new firmware. If putting "that PCI card in it" means putting a PCI card into a Windows box with PCI slots, then that's probably the best way for you to do this.

Trevor, Nick, tLarkin, et al.,

Trevor thanks for that rundown. It helped me, so likely it will help others.

No I did not mean I was going to try plugging a PCI card into a PCIe slot.

Nick (macsolver) is helping me use a PC tower environment to 'flash' ROM in a 7800s graphic 4x AGP card which can be made compatible for use in a G4 dual 1.25 MDD with 2GRAM.

I just successfully installed a second (new) e-g-force4 mx 440se card in a PC tower. Its current display card is a more powerful g-force AGP card. According to Nick I need to have a second display to use since I will pull PC's current AGP card and plug in that 7800s card which needs its ROM flashed. Then I can use second, just installed display, to do actual flash programming scripts.

That's my next step. I'll post soon (within next day or so) when I have some results from that.

Sorry for any confusion on my part.

Thanks so much, Nick, Trevor, and tLarkin, for this superb assistance,

eValuone.
