7900gtx for osx snow, how?

[josje22]

hi there,

I just installed osx snow, and I want to use my old 7900gtx, but I can't get it to work. HOW do I do that? I read that some of you also have an 7900GTX, bios flashed to the bios available here for gtx 512 or the fx5500. I tried both bios-ses, but no luck. Is there anybody with a proper working 7900gtx on snow?

If not, or If you think it's not possible, then I don't want to waste my time with this anymore. So my last chance is this forum, pffffff.

my sys:
my system:
- asus a8n-sli premium
- leadtek winfast px7900gtx extreme
- osx snow 10.6.2 hazzard

I didn't load any injectors.
before biosflash :

So no resolution options and no quartz

What I tried is to use EFIstudio, and patch the com.apple.boot.plist with the 7900gtx 512 bios from aquamac. There was no fx5500 in the list.

During the 10.4 tiger times there was a way to change strings in the NVDAResman.kext, NVDANV20Hal.kext and some others, but I never read about them anymore since 10.6 SNOW

And what about the injectors in many tastes?

BUT, maybe my specific 7900GTX original rom must be modded from 256 to 512, to use it well in SNOW, But I asked aquamac to do it , like he did it to his own 7900GTX. but still no reply, I hope he's reading this mssg. (my original rom is attached)

Hey dudes, pleaz help me out, I'm getting CRAZY
IF IT'S POSSIBLE, HOW??

So is your card a 512 mb. Did it work/did you try in leopard?

hi there again,

I think I got some. I reflashed the card with your aquamac 7900gtx 512 bios. Then used the efistudio and selected the 7900gtx 512, and manually added the given hexcode into the com.apple.Boot.plist.

I have multiple resolutions and hardware accelleration I think.

Thanks for your interrest, I'll paint my own name on the wall, heheh

ps. thanks for the aquamac bios. Is it hard to change my own original bios from 256 into 512?
I tried to find the hex values, but couldn't find them. Well aquamac, still if you can do this to me, i would be very thankfull, I think with my own modified bios I can keep the overclocking features.

But for now, I can sleep finally, bye (nice forum)
