Geforce 7600 GT EFI Strings & Snow Leopard

djspacee · November 9, 2009

Hi guys,

If anybody has got any gefore 7600GT working using EFI strings help would be very much appreciated. I've got snow leopard fully working with DSDT by following this excellent guide, (http://www.insanelymac.com/forum/index.php?showtopic=184367) but for some reason my no EFI strings that i try (which I have got in com.apple.Boot.plist in my /Extra folder), taken from two sources, will work.

The first source of EFI strings for my card is

http://www.insanelymac.com/forum/index.php?showtopic=113967

The second source I've tried is EFI studio and neither do the trick.

infact, the first source was the only string that gave me a working graphics for Leopard and not the one from EFI studio, but it was worth trying anyway.

I know that the 7600 GT does work with snow leopard and EFI strings because it has been confirmed here and in quite a few other places that I've read...

http://wiki.osx86project.org/wiki/index.ph...p;printable=yes

I've also tried modifying the com.apple.Boot.plist in SystemConfiguartion, tried using identical copies of them in both locations, nethier helped. Iv've also tried NVDANV50Hal.kext and 0.2.1 NVInject in my /Extra/Extensions folder but to no avail.

Any help would be very much appreciated.

Thanks

This is my current com.apple.boot.plist (the same EFI string working fine on my leopard installation).

Actually guys it will work fine if you switch to i386 mode in your com.apple.boot.plist

Here is my file

Adjust to your taste keep in mind this is with my custom dsdt.aml

I would like to thank scrax A true guru for all the help with dsdt.aml

Cheers, I need to figure out how to do a hardware signature

Hi djspacee,

Did you figure it out? I have also have 7600 GT (256mb) and am having trouble getting QE/CI to work.

Thanks,

I have the same card ge force 7600 gt , on xxx 10.5.6 perfect like in 10.4.8 jas , yesterday i have tried iportable snow on a usb key and , the gefoce don't go in extended monitor , i , can't change the resolution i can ave two desktop .

I have installed the classic nvidia driver , i don't . have efi , i don't have mach_kernel , someone can help me ?

i have patched DSDT, THE USB KEY WORK , but i want to fix audio and video .

The problem why your graphics card does not work is that you must put arch=i386 instead of arch=x86_32.

i have 7600 GT 256Mb and i am using it with snow leopard 10.6.3. QE working perfect even i can play call of duty 4 and tomb raider anniversary. So the problem is, this card is not working under 64 bit mode so you have to boot your OS in 32 bit mode. I am in search to fix this and make my card work in 64 bit mode.

Don't worry about 64 bit programs they will still work in 32 bit OS. I have tested a lot of applications and they work with no problem either 64 or 32 bit.

Here's my com.apple.boot.plist You can use it if you want.

Just add your graphics card EFI string if you have different card. This is for 7600 GT 256Mb.

Note: The easiest way to test if QE working or not is adding widget to dashboard. if ripple effect appears when you drop widget then you have your QE working.

My Specs.

OS

-Snow Leopard 10.6 Retail Disk. 10.6.3 Combo Update installed (with update guide provided by Netkas.org).

-Chameleon RC4 (installed with lizard.app)+ DSDT.aml (for CMOS reset fix)

HARDWARE

-MSI P965 NEO

-MSI NVIDIA GeForce 7600 GT

-TwinMOS 2GB Ram

-INTEL Core 2 du E6420 2.13 Ghz

Some APPLICATIONS

-Creative Suite Deign Premium CS5 (64 bit) - working perfect

-Ableton Suite 8 (32 Bit) - working perfect

-Kaspersky Antivirus 8 (32 Bit) - working perfect

-Toast 10 Titanium (32 Bit) - working perfect

-ILife (imovie, idvd, iweb etc.)- working perfect

-IWork (pages, keynote, numbers)- working perfect

Hummm... In your opinion, is there any hope of waiting for the right kext that will run in 64-bit under 10.6.3, for the 7600 GT ? I'm so disapointed !!!

U dont have to worry things if you dont have more than 4GB RAM. if you have less than 4gb either in 64 or 32 bits the OS will work the same way and the applications as well. And in addition most of the popular applications doesnt have 64 bit compatibility so 64 doesnt bother then just use it 32. those who have 64 needs more ram they also need more graphics memory and cpu power. so i dont think those 64 applications are stisfied with 256mb vga. but i think 32 applications are fully satisfied .in suumary if you can boot in native 64 with 7600gt and test it with native 64 app then go back to 32 bit mode and test it with the same 64 app --> No difference. Only thoes apps use more RAM power then VRAM will have diffrence. I mean if u use VGA powered apps than dont get disappointed about it. but if u use RAM powered apps than u can only use 4gb in 32 mode.

I think this little explanation helps you to see the picture.

I use 64 and 32 bit apps and i now updated to 10.6.4. Everyting works fine again.

but i will still looking for native 64 bit mode with 7600gt.not to see how well it works but to see it is possible.there is a chance because it is working in 32.

Instead of waiting u can use it and keep your eye on forums for the solution. or u can choose another alternatives like improving your vga which is compatible with 64bit or For real deal get a REAL APPLE MAC Computer and get more than you want (if you have enough $) --> thats exactly what i am going to do soon.

Hello:

I have an exactly same card with you, but I have been failed for dozens of time which can not install the driver for this graphic card, neither the resolution can not adjust or the QE/CI can not enable, now the system is crashed again in this early morning. I am wondering if you could help me on this. I am using Boot Think to load the snow leopard and try different kext which all failed. My email is: jerry88599@gmail.com and looking forward for your reply.

The hardware ID for my graphic card is:

0x0391

Thanks again.

Try to use chameleon rc4 and dont forget to configure your com.apple.boot.plist add your vga efi string as i hav written above or copy whole lines to com.apple.boot.plist. i will send u detailed info 2 ur mail when i have time to write it.

Actually it should work the same way with up to 32GB RAM, I think you must be confusing Snow Leopard with Windows.
