Can't install HD4000 Graphic kext

Question

First of all, hello guys and thanks in advance for your support.

I desperately need your help.

 

I have a laptop, Acer E1-570 where I successfully managed to install Niresh Mavericks 10.9

 

I have Chameleon bootloader and at first the system didn't want to boot.

It only booted with -x boot flag that's it safe mode.

 

After some advices around forums, I removed all the kexts files relating the graphics from /System/Extensions/Library and now it's booting fine without any boot flag but I have no internet and no graphic acceleration.

 

The graphic card is correctly identified but no kext are loaded.

 

As I said, I have the HD 4000 integrated graphic card and I don't know what to do to install the correct kext file. I tried everything but every time I install the AppleIntelFramebufferCapri.kext , Mavericks won't boot and I don't know which boot flag should I use but I tried almost anything.

 

Could you please, please, give a hand with this? :(

 

Thanks again guys

Solved. Just had to update BIOS to v. 2.06 and then Mavericks booted fine with GraphicsEnabler=Yes without touching or installing any custom kext file.
