Author Update #1 @shadowsa 2010-12-28

the version im currently using is the latest from the website

Author Update #2 @shadowsa 2011-01-04

took some time, i tried and no lo¥uck 7800 gtx is not working with the suggested method, maybe its not supported?

Author Update #3 @shadowsa 2011-01-06

so here is what i achieved till now, i installed iatkos 10.6.3 s3 v2 and after installation i have qe/ci enabled BUT if i update then it wont work anymore or even without update only if i modify the extension and the Extension.mkext Cache file gets updated then it doesnt work anymore, so i was thinking i can extract the cache file and just use those extensions, which i tried but after all i tried i cant get it to work anymre but if i put the Extensions.mkext cahe file inside then it works. so the 7800 should work but the question is how, btw. how do i use dsdt file? i never used it, or at least not that i am aware of or at least not concious.

AHH btw. it is PCI-E

Author Update #4 @shadowsa 2011-01-18

i didnt get anything to run yet, almost everything is running in 10.6.6 but qe/ci is not running on my machine with 7800 GTX strangely even dual screen is working

Field Note #1 @ozziesironman 2010-12-27

just run graphicsenabler=y. my old 7900GS was immediately picked up by it and worked FLAWLESSLY. make sure you use the new chameleon bootloader. hope this helps

Field Note #2 @ozziesironman 2010-12-28

r683 or whatever, right? remove any enablers, (NVInject, Natit, NVEnabler, etc) and reboot, and at the disk selection screen, (chameleon screen) type "GraphicsEnabler=Y" without the quotes, and if it works, go into your chameleon preference pane in system preferences, and check the box next to 'graphicsenabler' and click back then you're done. thats how my 7900 was picked up, which is obviously a tad newer than your 7800, so yours should work. good luck

Field Note #3 @ozziesironman 2011-01-05

That's weird. Do u get a black screen at boot with graphicsenabler?

Field Note #4 @lemonsoda 2011-01-06

you will get this working

is the card agp or pci express?

you will definately get this working using dsdt and you can match the same id's as a apple 7800 card. It does sound like you need to patch the nv4 and geforce kexts with your id which is not needed if you fake the id in dsdt (a smart trick i might add)

let me know

LS

:

also you can ask the guy here what he did with his 7800gt card. however, that is definately pci express

dsdt is kinda a PITA unless you know your hardware in and out, but is the absolute best way to achieve hardware injection, and if you can do it, then DO IT. you will not regret it.

if not... try an injector, such as silent natit_64. (its both x32 and x64, dont worry) . thats how i got my old 7950GT 512MB recognized and fully operational under 10.6.3. (but have since upgraded to a GT240 (though downgraded in OSX openGL performance seems to work better... plus the 7950 blew up cuz i had it overclocked to the moon in windows).
maybe NVInject will work for you.

if you want to stay away from injectors (as they get modified every update and you have to reinstall them) use EFI studio. i believe it has a string for your card. (cant check now because im on my ancient iBook G3 while windows 7 is installing on my hack... osx drive unplugged, of course,)

but if you want to try the DSDT, check out this link. http://www.google.com/search?hl=en&client=safari&am… ↗

take off the second monitor and reboot. i had that problem with my 7900GS

Field Note #7 @krillinballz 2011-02-04

Try Multibest 3.1.0 or Higher Use thier Enabler for the nivdia cards and see if that works got my 8800gts working like a dream. Maybe it will work for you.
