@vivek_jindal  Is it possible in your BIOS to disable either of the graphics cards ? 

 

Otherwise try these steps : 

Try these flags one at a time, if nothing  works try different combinations of these flags:

 

1) Boot with GraphicsEnabler=Yes

2) Boot with GraphicsEnabler=No

3) IGPEnabler=Yes / No

4) IGPlatformID=0166000A

 

If still nothing works try this kext package. Install both kexts with kext utility and reboot.

@vivek_jindal If it's possible in your BIOS to disable the Intel HD 4000, then do it and inject GraphIcs through Clover for the Ati 5850 (you can find a list of framebuffers and other resources online). Otherwise you may be stuck with the Intel HD 4000 Graphics which is not nearly as good as the ATI.

@vivek_jindal I think you should start a new post for that separately. 

As for the Intel Centrino wifi it will never work unless apple starts including those cards in their own computers.

The Realtek should work fine, just search online : Your Model No. + kexts
