Hi, the Nvidea 8800 is only in the 24" imac, the Nvidia 8800 is also nothing like the cards from the other models, if you wish to upgrade your 24" imac (the one with the Nvidia 8800) you have no choice but to replace it with the exact same video card another nvidia 8800. Several reason, if you are interested i will spell them out in my next post.
 
Can I also just add, if you dont understand what you are taliking about might I suggest that you do not offer advice as it is most off putting, the earlier White Imac had onboard video built onto the motherboard , that is all of them except the 24" 2.1ghs core duo this was fitted with an MXM card either the Nvidia 7300 or 7600.
 
The aluminium 20" and 24" core duo also have MXM cards but once again not all of them, the odd one was onboard graphics, I have managed to swap cards amongst most of these , except the nvidia 8800 , as the nvidia 8800 was a unique style of MXM, ( all the others were MXM II), I am at this moment in time trying to mod a newer version Nvidia GT130, I am trying to change this card to something beefier like the GT230 or GT250 with more onboard ram, if anyone can help with the EFi for one of these I would be very greatful even if they could point me in the right direction to create my own, I can do the rest once I have it.
 
the correct discription for the 24" Imac Nvidia 8800 GS is MXM HE, I do believe that you can now get a Nvidia 9800 GTX & a Nvidia GT280, both of these are the MXM HE type, I am guessing that as long as there bios is big enough to take the 8800 GS EFI firmware, then that could be an upgrade route, the card would report a slower clock speed (due to the 8800 EFI firmware) , but am pretty sure it will run ok , I no loger possess this version of the Imac , but would be very tempted to give it a try, you would already need to have windows on there so you were able to update the card, I am pretty sure trying to install this with a faulty card woud be a recepie for disaster.
 
You could always increase the bios size with a 1 meg bios chip, but again am pretty sure the original will be big enough to hold both the Bios and the EFI.
 
The 2600 Pro is an MXM II , no way will any other MXM card version work in the slot built for the Nvidia 8800Gs, don't take my word for it, there are plenty of other site's that discuss the compatibility of MXM card versions(you might notice that both logic boards have very different part number).
To be double sure I can confirm that I have tried to make it work without any success.
If you have the 24" Imac with an Nvidia 8800, then there is only the route I have mentioned, if you are lucky enough to have another card in there then you are more likely to have MXM II, you will be able to fit any number of cards in there, but then we are back to the EFI problem
