I've worked hard together with the Chameleon team to make this possible.
Big thanks go to Prasys for implementing the GMA GraphicsEnabler fix.
I devised the solution for getting CI/QE/OpenGL on the GMA card I'm using now...
I also fixed up some warnings in the GMA graphicsenabler.
This fix is for Snow Leopard 10.6.2...

Download:

Sources of bootloader:
Check it out from the Chameleon forge site (under branches/andyvand).

Enjoy this great solution... :cool:

New fix for 10.6.3 including 0x27A2 for those were it doesn't work (10.6.3):

Does this just allow us to replace GMA950 EFI String with GraphicsEnabler, or is it making it possible to work without bin-patching AppleIntelGMA950 & AppleIntegratedFramebuffer Kernel Extensions?

I tried to install this on my dell mini 10v and it failed to install the bootloader.

EFI injection is done by GraphicsEnabler.
But for Intel GMA945 (0x27AE8086) the id within the plist of the two included kexts needed changing, also there was the need to change 8680A227 to 8680AE27 within the binaries.
If bootloader install fails, extract it with Pacifist and install manually.
If you have Chameleon 2 RC4 installed you can just copy boot into /...

This fix also works for 0x27A28086.
In this case you do everything but KEEP THE STOCK AppleIntelIntegratedFramebuffer.kext and AppleIntelGMA950.kext

Would this work if patched intelgma950 kexts are in /E/E or do they have to be in /S/L/E only?

Is it possible to add 0x2592 (GMA900/915) to it? I am still using Elliot's driver.. I tried to put Elliot and patched AppleIntegratedGMA into Extra (I even tried to add the 3 extra dependencies..) anyway that didn't work so I had to put it in the /S/L/E...

Another problem was the mach_kernel.. put the patched one into /Extra but it didn't work..
Should be possible if you replace a compatible id (check Info.plist for wich ones are present).
For patching the binary replace the byte swapped id:
-- Example --
Thus in Info.plist:
0x27A28086

Becomes in binary:
86 80 A2 27

Replace the device id closest to your card with your one...
Checked...
0x25828086 in Info.plist becomes
0x25928086
for both plists

for both binaries use 0xED to search and replace (in hex).
86 80 82 25
to
86 80 92 25

Binaries are allways present in Contents/MacOS (if you didn't know it).
Install both in S/L/E instead of original kexts.

Follow other steps in tutorial and if the bootloader install fails install Chameleon 2 RC4 stock and replace boot with the attached one...
Hope this helps you out...

New version: This one also detects secondary display + auto patches (and it shows in System Profiler).
It also fixes resolution support for 0x27AE8086/0x27A68086 thanks to the VBIOS ROM dump I made + code changes...
Use RadeonPCI.kext and RadeonDump -d for dumping Intel VBIOS (only works for dumping VBIOS though, not for register read...)
Please dump as much other GMA VBIOS's as possible so I can get more cards supported (GMA950 / GMAX3100 style).
It also would help all of the Chameleon devs majorly.

New version available for 10.6.3 for these 2 cards:
0x27AE
0x27A2

Get first package too for new installers

Yeah but it is previous version.
New version fixes some OpenGL issues...

Would this help at all with sleep issues, I have no problems getting my gma950 working with stock kexts via dsdt but I still can't get sleep to work.

andyvand

04-24-2010, 08:29 PM

No idea since I still don't have sleep working on my machine either...

scififan68

04-24-2010, 08:48 PM

Do you have sleepenabler.kext in /Extra/Extensions ?

andyvand

04-25-2010, 05:23 PM

Yes SleepEnabler.kext = present and my machine goes to sleep but after wake it just boots up and fails to recover sleepimage...

Sleep enabler doesn't do anything for me.

@Andy

Maybe AppleLPC kext is not loaded on yours, and / or does the debug-version of IOUSBFamily let errors about UHCI appear at your dmesg?

I experienced those two things to be reasons for Wake from Sleep not to work on some setups...
Ah yes. Your right. I remember having problems with sleep because of my UHCI. To fix it add
<key>UHCIreset</key>
<string>Yes</string>
into your com.apple.Boot.plist

Hi experts.
I'm a total newbie in OSX86, but I managed to get a Hazard OSX 10.6.2 up and running on my Lenevo R60 laptop.
The only thing that's missing is the GMA945 videocard.
The pkg-installer faild, so I tried to replace the boot-file in /.. and install the two kext's downloadable in the first post. I included "Graphicsenabler" in the com.apple.boot.plist. No luck. So I have given up. The screen works, but only in 1024x768 resolution. And therefore the DVD-player will not work.

Now I have the pre-boot verbose PCI UUid list with "press any key to continue" before the chameleon logo-screen.
How do I get rid of this verbose (and "press any key to continue") during bootup ?
I have no "-v" in com.apple.boot.plist.
I think this PCI-list shows up before com.apple.boot.plist is read. Is this correct ?
I did not make a backup of my old boot-file in /.., so I can't get back to my old way of boot.

Hope you can help.
I'm sorry for my "newbie-question", but I'm ready to learn !

Regards
Stha

Wow. Thanks for this - finally found a way of getting some support for my Vaio W in 10.6.2. I'd tried a few fixes and this one gave me the most success.

One big issues - when I follow all the steps except updating the bootloader the only output I can get is via VGA, the netbooks LCD goes black - but when I install the new bootloader (from first post and the one a few posts later) it causes the computer to sleep after the gfx initialises - and from what I can tell still only works to VGA too.
Any pointers?

==================

going to reboot now.

Edit: Just rebooted, NO KERNEL PANIC FOR FIRST TIME AFTER REBOOTING YUHOO ( sorry, i got excited for not seeing stuck at boot thingy).

but no resolution improvement, idont have com.boot.plist thingy, i tried to install chameleon R69 version i got from some rapidsharefile you posted in chameleon mailing list, it failed to install sadly :( . how to go about this now? :(

EDIT After 24 hours:-
So this time after reinstall, I came across NetbookInstaller (http://code.google.com/p/netbook-installer/) , It took some 20 mins to finish its job on a plain iAtkos S3 installation on my MSI U100 netbook, asked me password more than 2-3 times, after it finished, i rebooted and viola , i got hi-res desktop, but its just weird res. check attached images.

Andy, how to go about installing your files now? should i also replace boot file that you have attached in later replies? waiting for your kind reply.

Don't you have any problem with the mirror mode?
My screens get with vertical horrible lines...

krrr

06-26-2010, 06:27 PM

I just used my LCD monitor as second monitor (which is extended space,I can move one window from 1st monitor to second) ,so no issues there. is this what you mean by mirror mode?

y333

06-26-2010, 07:43 PM

krrr> In fact this is extended mode :) Your 2nd screen acts like an extension of your deskopt. I asked about mirror mode that is the mode where the 2 screens shows the same content :) You could find the checkbox in the Monitors Settings (on the middle tab when the 2nd screen is connected): "Mirror Displays".
http://farm4.static.flickr.com/3214/2592015479_9ed49788ba_o.png
Take care, If you have some scratchy screen like me, when unplugging the monitor, you will be able to use your computer again but anytime you will plug the monitor again, you will see those beautifuls artifacts. To disable the mirror mode, you could use this tool from a terminal http://www.fabiancanas.com/Projects/MirrorDisplays/ (or delete your monitor preferencies). As a result you will be able to use your extended mode again :)

@y333, ya the mirroring didnt work, gave me stripes , i was scared that i might have to reinstall because the utility you posted doesn't work.

fortunately, i found http://eruvia.org/software/osxmirroring/ and this one worked from terminal. phew.

HEy Andy, as i already say you on insanely, i did these modification:

i changed all 86 80 72 27 to 86 80 AE 27 for ae27 but mirror doesn't still. Solutions? Thank you

EDIT: i've try to change all id, 86 80 72 27 to 86 80 AE 27, then 86 80 82 25 to 86 80 AE 27, then 86 80 92 25 to 86 80 AE 27 , but mirror never work. You sure that the patch is only this here?

Is there any solution for mirror ?

Yes, use one of the 0x25XX series inside it to swap it.
Remember you need to swap your bytes inside binary (e.g. 25928086 becomes 86809225).
Check Info.plist for a card ID and swap it like I told you.
Next replace that with the swapped ID of your card.
Last but not least you need to adapt the Info.plist in order for it to work.
This must be done for both kexts (and then installed ofcourse)

It appears to me that this is already built in though. Like it looks like my device ID is already in there.
