GeForce 8600 GT and MAC Support

grandlorie · #1 12-13-2009, 11:11 PM

Hi All

i Managed to install IPC 10.5.6 on my Toshiba Qosmio G40 2 weeks ago, almost everything is running fine except :
The Vidoe Card, GeForce 8600 GT 512MB, i tried all the options included within IPC with no success..... all of them are giving me Black Screen.

for 2 weeks looking all over the forums and could not find one straight solution.

i am not here to Ask a solution because seems to me no one knows the answer.
i am just wondering if this Card not working at all with anyone why in the world they include it in the package.

Just make it clear and say GeForce 8600 GT 512MB not supported and whoever got a laptop or a PC with that thing {Do not even try}
Aam i right guys?

GeForce 8600 GT 512MB works just fine, as I have used one in my hackintosh,

BUT, I was using a Desktop PC, with a PCI Express Video Card, and had a
vanilla install from the retail DVD

So there are two things to think about,

(1) Could it be that because its a Laptop IGP and not a regular video card
(2) Could it be the Distro you are using,

Have you tried EFI Studio?

Hi will1384
First Thanks for you reply.

Yes, i tried EFI Studio and i choosed GeForce 8600 GT 512MB from the list and after that i restarted the laptop and booted with -v(and-f) and also started again normally and in all cases what i got is just black screen. the computer is running but with black screen (no mouse pointer shown).

so unfortunatly EFI studio did not work with me.

Also i tried to use ox86 Tools Utility by trying to add EFI and i choosed my card but when i tried to save i...t it gave me this message:
/bin sh not exist

any thoughts.

don't install your video card from within IPC, just use universal osx86 installer
it works great with it . For me, it worked on a laptop with a 8600gt 256mb.

" , just use universal osx86 installer " can you please explain more how to do that as i am not that MAC expert.
thanks

- Also if i installed something (talking video card) and i got black screen. how can i delete that and go back to the previous state? or do i have to make a new installation?

You may end up having to get your NVCAP info, you dump the
Video ROM under windows or dos and run it threw NVCAP Maker
on the mac, I use GPU-Z under Windows to dump Video ROMs

The NVCAP info, its info on the video output ports on you video card,
you will get a set of numbers like this

"04000000 00000300 0C000000 00000007 00000000"
or
"04000000000003000c0000000000000700000000"

Now go into EFI studio and select your video card, click "Add Device"
now click "Save XML" now open that file with ether "PlistEdit Pro"
or "Property List Editor" and add your NVCAP info and save the file
now open EFI studio and click on File then Open XML File, and install
like you would normally with EFI studio,

Or if you are worried about it not working, just edit your
com.apple.Boot.plist file in the /Extra folder, and use Empire EFI
Boot CD or the The myHack Installer installed to a thumb drive
to boot with if you unable to boot after the changes

This way is almost the same as before

Go into EFI studio and select your video card, click "Add Device"
now click "Save XML" now open that file with ether "PlistEdit Pro"
or "Property List Editor" and add your NVCAP info and save the file.

Now copy com.apple.Boot.plist from the /Extra folder to the desktop
open it with TextEdit and add

Code:

<key>device-properties</key>
<string>PASTE YOUR HEX HERE</string>

Like this

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Kernel</key>
    <string>mach_kernel</string>
    <key>Timeout</key>
    <string>5</string>
    <key>Kernel Flags</key>
    <string>arch=i386</string>
    <key>EthernetBuiltIn</key>
    <string>y</string>
    <key>Graphics Mode</key>
    <string>1024x768x32</string>
    <key>device-properties</key>
    <string>PASTE YOUR HEX HERE</string>
</dict>
</plist>

now open EFI studio and click on "File" then "Open XML" File, now click
on "Hex String to Clipboard" and paste were "PASTE YOUR HEX HERE"
was.

Code:

<?xml version="1.0" encoding="UTF-8"?>

</dict>
</plist>

And now copy it back to /Extra folder

I found some NVCAP numbers for you to try

Dual Display working through VGA and S-video on Go7400 on HP, NVinjectGO did it!

and

[DVI SOLVED] Gainward 8600GT 256mb VGA-DVI-HDMI

Yea that happened to me a lot, then I learned that trick about only putting
stuff into the /Extra folder and using something like Empire EFI or myHack
to boot.

When you use the CD or Thumb drive to boot it ignores the /Extra folder
on your hard drive, letting you boot if you have messed up.

But if you just install to the "/System/Library/Extensions" and or
"/Library/Preferences/SystemConfiguration" that boot trick wont help

And EFI studio installs to "/Library/Preferences/SystemConfiguration"

OOOh

easy on me i am lost now, i am not that MAC guru as you..
so now i need to ask you this:
-if i have a black screen like i am having now. can i still boot using any method or i have to reinstall?

- what do you mean by installing to extra folder? how can i do that? i kinda of smart i swear but i am a 20 years PC user and non in MAC so please explain it more to me? for example for the graphic Card where to get the file and where to save it because now i am confused?

sorry for that but thanks
Lorie
