I have the Mac Pro Model 1.1 2ghz.

What sort of options do I have for a custom flashed card? I'm quite interested in the ZOTAC GeForce 8800GT AMP Edition.

Would I need to flash the card with a EFI32 image?

You need an EFI32 ROM and some way of actually editing that ROM so the card retains its BIOS clocks. When running in OS X you will only get the default clocks.

You need to check card you have now first.

The utility you need is nvflash 5.57

You will also need DOS to use it. You can Create a DOS bootCD with FreeDOS.iso that you can download here.

To see your ROM ID using the Nvflash tool the command is: nvflash --check

That should return information about your GPU, and your ROM ID.


But I think you have no chance of getting that card to work in that Mac. We are using cards that have the same GPU as the ROM from from our Mac's. It's just a ROM swap. Getting yours to work is a much more involved process, and I don't think it will work regardless of what you do.
 
I was under the impression the 8800GT would be released for the 1.1 Mac Pro in the future?

I'm not sure I know what Mac Pro the 1.1 is. You said 2GHz so it sounds old.

I did give you instructions on how to find out your ROM ID. Post your ROM ID, and we'll tell you what we think. :)

Wait what card do you have now?
 
if you have a 1.1 mac you have a pre 08 mac and will not be able to run 8800.

Thanks, it work :).

Last thing, what's the image you all used ? This one ?

That's the image everyone has been using; however I haven't been able to load it yet. My PNY card had a 64k flash so I sent it back immediately. I have an eVGA on order, and I'll report back on Wednesday if it works:

I saw a bunch of these at Frys but they wanted $280+tax. They have green PCBs... for what that's worth. :rolleyes:

I'm not sure that statement is the absolute truth to his question. What evidence makes you think that no Mac but an early 2008 is going to run a 8800?
There are hackintosh users using other solutions like nvinject to get non supported cards to run in x86 machines. He wont be able to use our method, but that doesn't necessarily mean there isn't a way to do it. THey have been using unsupported cards in their Hack Pro's for a while.

All the hackintosh's that have been able to run other cards have been modifying firmware from similar cards. The pre 08 mac pro's are running a older revision of efi that is no longer supported. So far apple hasn't made any signs that they are going to upgrade the efi firmware for the older ones to the 2.01 standard release efi. The 8800's are efi 2.01 standard release and will not work in the previous revision of efi that the older ones are using. How ever it is possible if a card was produced using the older efi type that i can be run in the new efi type. What remains to be seen is if it is possible to take the so called 64efi and turn it into a 32efi so that the older computers can run it.

Your pointing me towards a rumor thread, but Apple and Nvidia both said they are working to get the 8800 upgrade to the earlier than 2008 Mac pro. Apple didn't have any idea the 8800 upgrade kit wasn't going to work in the pre 2008 model when the listed it on their site. That's actually sad in a way, but funny in... well the same way. :)
 
I never said that they were not working on the problem. But what i got from what you said is that the current 8800's could work, which they do not. The thread also has the actual reason why the cards do not work.

I didn't mean could work right out of the box now if that's what you thought I meant.
 
Tried flashing a ZOTAC AMP! edition card but couldn't boot into OSX all the way.

Traded cards with my bro (he has a XFX PVT88PYDD4 w/ Black PCB) and it works great!
 
k

right well i have decided i will go with an evga 8800 or xfx alpha dog edition just waiting to hear back form overclockers.co.uk regarding my request to know rom size and returns policy.

So hopefully once i move in to my new house in a month or so ill have a dual graphics card mac pro yay

thanks for all your efforts guys

seems silly to pay apple :apple: £130 to take away the ati card when i can put that money towards a 8800 and have the ati :D as well
 
Hi all,

I just tried to flash a JETWAY 8800 GT and i am stucked.

After creating a FAT32 partion on which i copied the nvflash files ("_" + "cwsdpmi.exe") i plugged the 8800 card on my 2008 macPro with power plugged to the second DVD plug.

After reboot on a FreeDOS CD and typing "1" then "2" i typed in C: nvflash --check. I got this message "bad command or invalid filename".
I tried renaiming the "_" file to nvflash : didn't work.
So at this point i can't even check my card's EPROM size to see if i can flash.

Does anyone have a solution for this. Thank's
 
Try typing "1" then "3"

When you get the A:> prompt, just type

c:


Assuming you already have nvflash on your hard disk's FAT32 DOS partition, and that partition is mounted at c:, this should put you at:

C:>

You should then be able to type, after the C:> prompt,

nvflash --check


Or, just type c:\nvflash --check

I just reread this part of your message. There's no "_" file in the nvflash 5.57 archive. Make sure you copy over the file NVFLASH.EXE. Maybe you need to download the zip file again?
 
I heard of two successful flashes with Jetway 8800 cards. They correspond to the reference design and look like Apples card (and have a green PCB)
But this brand doesn't seem very popular...
 
Thank's thagomizer for your help.

I confirm, i finaly managed to flash the JETWAY with green PCB and it works like a charm. My difficulties came from the fact that i had aunzipped the nvflash folder with stuffit and it messed up the names, that is why nvflash.exe had become "_" :eek::eek:

I bought this card yesterday in a shop in Paris and another guy managed to flash the same model bought in the same place. In fact the JETWAY was used by Lionel from "macbidouille.com" for his online flashing tutorial.

Notice that i have used the second power plug in the optical drive with a "Y" molex cable. I have plugged only one of the plugs. It works but it obliges me to keep the side panel open... I have to find a way to fix this.

:)

thagomizer: Was the cable you got from ATI the correct one? Thanks.
