Yep, link only works when coming form google, no idea what Nvidia has messed up there... 
It's the "Device Control Block 4.0 Specification".

link not working for me

The URL got modified :

Code:

url=http://ftp://download.nvidia.com

maybe a ftp link in not supported on this forum which automatically adds http:// 

Anyway it is nice to see some progress here, for my part nothing relevant found.

Hey guys,

just a short question (mainly @ MVC/netkas):

Do you know if it's possible for Nvidia cards to make a 'hybrid' EFI which will show boot screens but doesn't have any injection, so the driver will pick the card up in auto-init mode?
With AMD cards this was rather simply done by injecting some garbage as framebuffer, but the Nvdia driver seems to be less robust (keeps crashing). I'm currently removing all ioreg injections from the Kepler EFI (about two thirds done), but I'm currently taking a short break after having bricked my card again

In theory this should reduce the necessary work when building a new ROM quite a lot because you wouldn't have to do any modifications to the vBIOS part (DCB, Upper DVI issue, GT640 issue, ...), so have you ever tried that approach?

[Fl0r!an]

Okay, after having patched out every single ioreg injection from the Kepler-EFI the drivers are still crashing 
Maybe the drivers are irritated by the handful of ioreg entries which will be set by the Mac's EFI, or there is a problem when handing the display over from EFI mode to accelerated mode in OS X.
AMD drivers are a lot more robust in this case, as they'll just fall back to auto-init mode when something is wrong with the injected keys.

Any modified the gtx 680 rom to work on gtx 770?

There is not, nor ever will be a "one size fits all" Mac 770 rom.

While the 680 and 770 are based on same basic core, by the time the board partners made the 770 they all went in their own direction with components. Most notably the VRAM, fan(s) and power management varied from card to card. In comparison, most 680 cards, expecially the 2GB ones, used similar parts, hence the ability to use the "Mac rom" on those.

MVC has a partner now in Europe who will be able to write rom and flash your card in a few months.

Whatever you do, don't try to flash 680 rom on it. Could easily lead to a brick.

Ooo nice if mvc flash cards on europe.....but wher is this mvc partener and how to contact him??
