I'm testing kext..

Ok without modified info.plist,kext boot in 1024x768,now im modifying info.plist..

- Don't work,only 1024x768 with right replication...D:

[G62]

the added feature is just user input in info.plist so its the same kext as before except that everyone can put his own panel timings the issue of res needs framebuffer which is what am trying to figure it out

[jaller]

ok..good luck!

[Duncan Leo]

Sorry but I only know basic coding
How does IOGraphicsFamily affect the back light and how does it cause the black screen when fb is loaded? Thanks

Is there a kext that tells osx what connector the gpu has? as in a kext that does only that and works for any graphics

[G62]

download sources of IOGraphics from apple opensource website and have a look at IODisplay.cpp IOBacklight.cpp and others you might find what am saying

[iWin32]

Just thought I'd give you a little update: Your new Kext with my EDID information works like a charm!!  Any progress with the Framebuffer?

[jaller]

News?

[G62]

framebuffer is not a one day work am trying my best to get it up as soon as i could if after all it will be a success

So what works? Native Res? Graphic Acceleration?

If you need it, i have extracted the AppleIntelHDGraphics kexts from Mountain Lion 10.8 Retail.

The Archive contains:

• AppleIntelHDGraphics.kext
  
• AppleIntelHDGraphicsFB.kext
  
• AppleIntelHDGraphicsGA.plugin
  
• AppleIntelHDGraphicsVADriver.bundle

All the kexts have the version 8.0.51

If you need other kexts from ML 10.8 Retail, please, let me know.

A pity that ML will be dropping 32-bit support... Maybe we should work on SL/Lion kexts since those are both archs (32/64)

Keep up the good work!
@G62 There is no rush for this to work! Take your time

Ppl don't rush him as well....

I don't know, but it is so hard (knowledge level) to (re)write a framebuffer for this card. That I really thinking, just don't buy a laptop with Intel 2000 HD.
I haven't tried, but would it work if you just replace your Intel CPU with one that don't has a GPU inside? (So just the core only?)
Or does the display out really needs the Intel HD?

[Duncan Leo]

Argh... the common misconception...
There are 4 Intel HD graphics. HD 1000,2000,3000&4000. 1000 is also known as the GMA HD or 5700MHD which were included with First Gen Core I cpus. 2000&3000 are Sandy Bridge gpus. 4000 is the Ivy Bridge. We are talking about 1000. 2000 might hopefully get support thru a mix of 1000&3000 kexts but our main focus is 1000.

[G62]

i think GMA HD 2000 and all the way up to HD 3000 are supported natively in AppleIntelSNB kexts so guys with those chipsets should  check other forum topics there are plenty of them in this site the device id of HD 1000 or arrandale or GMAHD 5700 are 0x0046 or 0x0044 for desktops i believe, if ur ids are something like 0x01xx or something like that ur probably using sandy bridge chipsets and not arrandale the decent way to know is the model of ur cpu if it starts with core ix 2xxx it is not a arrandale/clarkdale/ first gen core cpus

the framebuffer thing seem to be challenging more than i thought in the beginning but i will keep on working on it for the next couple of months till i have enough or i solve it eventually on the way.

[Duncan Leo]

@G62 what are the values for AppleSamplePCI? For a 1280x800 display? Or is there a program to extract it?

[G62]

@Duncan Leo the values depends on your panels properties and to know those values you should have ur EDID and or have a program to interpret it " it will give you all that values the priview should be like this from linux

So, is this finally working??? I dont get it!!!... why is the topic named as [FIXED]???/...  thnx to all that are working on it... GOOD LUCK!!!

Read the first post

[irako]

Sorry, but still dont get it... i did that guide a long time ago, and yes i get some acceleration but no custom res, but without it i cant work as i would like to, and erase my partition.

So, i read the entire post and what i understood was that G62 is still working on a framebuffer to get custom res, so we have to wait to our genius get it... if im wrong let me know please, also if need tester or if you make a complete guide, thnx once again

Yes.  You need to do that first.  Then, what you do is, like the post says, set up screen sharing (through VNC), and use Chicken of the VNC on the same computer to view your hackintosh.  After that, you can minimize the window and watch all former problems with QE/CI disappear (like distortions using Finder, Kernel Panics when loading full screen in applications, etc.)  This fix does NOT enable custom resolution.

Yes, G62 is working on a framebuffer.  He has made great progress in enabling our Graphics Card (still with 64 mb of shared VRAM) and getting it to our custom resolution.  Using a newer version with my EDID information, I got the kext to work.  The problem: Mac OS X doesn't know our graphics card has a new resolution, and it still is outputing 1024x768.  And before you ask, SwitchResX doesn't work.

However, I do have something new to report: When using this card with all fixes above, I was able to extend the amount of VRAM from 64 MB to 1280 MB!!  Here's what I did.  I did all fixes I mentioned (QE/CI fix, Chicken of the VNC fix, AppleSamplePCI.kext by G62), HOWEVER, instead of enabling Chameleon's GraphicsEnabler, I used manor's EFI string in my com.apple.Boot.plist.  This got it up to 1280 MB of RAM and getting the card name right in System Profiler.  I think it saying "IntelHDGraphics" in System Profiler is only a cosmetic fix; I'm not sure if the GPU is detected by OS X.  How can I know for sure?  And is anyone able to replicate my result?
