Re: BIOS settings, I recommend:

1) Ethernet = Enabled (rather than enabled w/PXE - you're not going to boot via a LAN image, are you?)

2) display: I would statically define iGPU (Intel HD) or dGPU (ATI Radeon HD) but not set the primary display to auto. Hackintoshes do not support GPU switching.

OS X supports VGA but it depends on GPU model or OS X version, sometimes a mix of both. For instance, VGA is unsupported with mobile Haswell HD4600 whereas I've seen it work OOB on HD4400-based laptops. IvyBridge HD4000 supported VGA output in ML but not since Mavericks. On my old Latitude D630, the nVidia NVS Quadro 135M supports VGA output all the way from SL to Sierra.

 

With your discrete ATI board, it should depend entirely on the framebuffer settings, i.e. the ATI Config personality you'll go for. The personality may also require binary patching.

i know on my 9010 the preallocated video ram is affected by what setting video mode is set to. if i recall auto gave me the amount needed for hd4000 to work in osx i would have to recheck that though as i am going by my memory.... and i am due for a new batch... lol

huge improvement!

 

I tried to install a i5-4590 in my PC.

And when the configure can install OSX in the 3020 I mentioned used, which also has i5-4590 cpu but H81 chipset and different video card. 

After a serial BIOS changes, the result is like the pasted picture.

 

In the normal boot procedure,

after this the APPLE icon should appear and install progress starts.

but on my 7020,

after this screen, the computer stop working.

 

I also noticed that on the 3020,

there are 2 more line about HDAxxxxxx (too fast to take pictures)

 

What should I do next?

Now I am seeing the install interface!

 

I am sure that

1. ES cpu prevents the install.

2. In optiplex 7020' bios (A07), someone option in "Preference" prevents the Install beside the common ones, such as VT-D and secure boot.

 

And the Inject-ATI option in config.plist is my last step.

Confused!

 

yesterday, after I installed OSX,

it has no audio device.

So I tried VoodooHDA2.8.5 first.

after failed,

I installed ALC1150,

added fixHDA in config.plist and then reboot.

The result is shown as 2.jpg the audio device works well and I pasted last reply.

 

Today, I removed legacy boot from BIOS,

this leads to many reboots because the display show nothing during boot procedure.

After the 7020 comes back,

I found the ALC1150 dose not work anymore.

After refresh cache, repair authority(with kext utility and kext wizard) and reboot many many times,

it never works.

 

I reinstall the OSX again, install ALC1150 and it does not work.

I found the AppleHDA is loaded, in 1.jpg, but it does work. 

 

And the efi in my install USB stick is also pasted.

I find the procedure but can not explain it.

 

I tried again.

If only install VoodooHDA285 or only install alc1150, after boot, the audio does not work.

When installed VoodooHDA285 and alc1150 both, reboot (for many times also), the audio works well.

 

After this,

When I install Xcode7, there is a warning. it says the AppleHDADisabler.kext has an error and cannot be used anymore.

After this, the audio will never work whatever I do. 

 

still confusing ...
