If you don't want to mod the BIOS as it might be difficult for some models, you could skip this step by adding 2 new kexts to /EFI/Clover/kexts/Other

Lilu.kext IntelGraphicsDVMTFixup.kext

 

Note:

While searching for the GUID  899407d7-99fe-43d8-9a21-79ec328cac21

I was able to find and extract the body of PE32 Image section

Converted it to text file

Able to search the text file for DVMT

0x795 and 0x796

Sorry missed search term DVMT.

 

So I have

 

DVMT Pre-Allocated, Variable: 0x795 {05 91 25 05 38 05 35 27 01 00 95 07 14 10 00 FE 00}

0x409C7         End If {29 02}
0x409C9         Setting: DVMT Total Gfx Mem, Variable: 0x796 {05 91 39 05 3A 05 BC 04 01 00 96 07 10 10 01 03 00}
0x409DA             Option: 128M, Value: 0x1 {09 07 3B 05 00 00 01}

0x409E8             Option: MAX, Value: 0x3 {09 07 3D 05 30 00 03}

 

What do I have to do next? I guess once the patch is applied I have to remove dvmtfixup.kext and restart and see if that works.

 

 

So I have to run code for EFI shell as per below

 

setup_var 0x795 0x3 or setup_var 0x795 0x2 (as I dont have 96M)

Hmm, give it a try with setup_var 0x795 0x3

 

 

There's another alternative, add to kernel and KextPatches the following (use Clover Configurator):

Name*= com.apple.driver.AppleIntelKBLGraphicsFramebuffer

Find*  = 00006002 00005001

Replace* = 00003001 00009000

Comment* = 0x591b0000, 32MB BIOS, 19MB framebuffer 9MB cursor bytes (credit RehabMan)

THanks. Ok will give a shot in 30 mins when I home. But bare in mind that I have intel HD 530 and patch above refers to 0x591b0000 which is intel HD 620.

 

Also after applying this patch should I remove dvmtfixup.kext?
