Here's my config. I'll try removing that driver as well.

Devices/FakeID/IntelGFX=0x80861616 is invalid. The vendor-id is LSW, device-id MSW. Unless it was your goal to prevent the drivers from loading, you probably meant IntelGFX=0x16168086. Read the Clover wiki: http://clover-wiki.zetam.org/Home. Also, no need to inject device-id when the native ID is supported by the driver's Info.plist.

Note: It also appears you have a patch masking the assertion. That is a very bad idea. The assertion is trying to tell you something is configured incorrectly. Address the root issue, patching the assertion will only move the problem to somewhere else.

I'm assuming the root problem is the stupid DVMT not being set to 96MB, but I just cannot set it no matter what I try, I've tried setting it through EFI Shell, I've tried to patch my BIOS to reveal the hidden settings, I've tried to hex edit the efivars through ubuntu, nothing seems to work. Also, the patch for the framebuffer kext doesn't seem to work either, neither does directly hex editing the binary. I'm not sure why none of it is working, I feel like it's probably something simple, as usual.

I think you'll need to fix the DMVT issue. Everything I read so far points in that direction.

Or make a solid attempt to patch the framebuffer so that the framebuffer configuration (associated with the ig-platform-id you're using) matches your real BIOS configuration. This is not the same as masking the assertion. It will require real research and understanding of framebuffer configuration.

Is there a solid way to see if I've correctly changed the setting? I stupidly took the easy way and just dedicated my whole SSD to this OS X install, so now I don't have a windows partition to check, but I assume if I get it correctly changed things will start to work.

That's the other thing I was just looking into, I was trying to find what the change from 39CF763C to 39CF773C means, and how it was reached, I know that my DMVT is currently set to 32MB (or at least it was by default, not really sure if I've successfully changed it since then but I know windows always reported 0MB of dedicated memory). I'm really hoping I can just find a way to change the DMVT, because researching the framebuffer seems infinitely more complex...

If you've been reading along like I have, you should realize the only way to check that has been mentioned is by checking in Windows in the Intel graphics control panel app. If you wish to check, you should probably re-install Windows.

Hi, I was wrong, it's running native 3200x1800 :)

However, yesterday I was still experiencing some freezing problems. few minutes after start, osx just froze. I tried few other versions of fakesmc as suggested, but it didn't help. Then I changed the DVMT few times, and after last change to 96mb, my dell was bricked. I always checked 2-3 times if the setup_var command is written correctly, so I don't know what happend, it was just bricked.

Today I got brand new xps13 replacement and I decided to do NOT any BIOS modifications, just disabled secure boot and enabled legacy support. And guess what, after patching the AppleIntelBDWGraphicsFramebuffer (Find 39CF763C and replace it with 39CF773C) it started without any problems! And no freezing issues (got it running a few hours).

Regarding the IOKit patch I used this command
Code: 
sudo perl -i.bak -pe 's|\xB8\x01\x00\x00\x00\xF6\xC1\x01\x0F\x85|\x33\xC0\x90\x90\x90\x90\x90\x90\x90\xE9|sg' /System/Library/Frameworks/IOKit.framework/Versions/Current/IOKit
		sudo codesign -f -s - /System/Library/Frameworks/IOKit.framework/Versions/Current/IOKit

If someone is interested, there's my entire EFI folder as attachment. I've got WIFI working with asus usb n10, sound with latest voodoohda, touchscreen is also working. I'll continue to work on other functionality.

Ugh I don't understand at all how you got the graphics patch working, I have the exact same system as you, minus the screen resolution, and when I do the exact same thing you did (patch the framebuffer through config.plist), absolutely nothing happens. Is that literally all you did? Just what's in your config.plist? And it worked? I've copied your plist and used it for my computer and it doesn't work, and I cannot think of a single reason why it wouldn't.

Could you possibly post your patched AppleIntelBDWGraphicsFramebuffer binary?

As I've stated previously, I don't think that patch is a good idea.

And if you wanted to create the patched binary (no reason to do so with Clover because Clover can do it via KextsToPatch), you can simply follow the steps I show in my post.

OK, I have no idea why it's not working for me then. I've copied it exactly the way it is in other's configs, and it still isn't working, so I guess I'll just hope that someone who has my same computer can reply here.
