This patch "0x59160000, 80MB framebuffer 12MB cursor bytes (credit RehabMan)" requires 128mb DVMT-prealloc.
Make sure you set DVMT-prealloc to 128mb in BIOS.

i am unable to change dvmt-prealloc in bios and i can't seem to find a guide on how to do it through shell

Hey. I don’t think you need the patch considering your laptop was booting fine without one earlier with skylake. I'd say remove it and try again. Mine would hang with it. Although my bios is already set at 128 so I probably didn't need it.

To get kabylake working, I literally did exactly what you told me to do except with the kaby ID's instead. When you first change everything, use the 0x12345678 id and the bootflag -f to boot. Afterwards run the kextcache command and remove the bootflag. Then set up the proper id's etc... according to the link I shared and reboot.

I installed Lilu.kext IntelGraphicsFixUp.kext FakePCIID.kext FakePCIID_.kext and FakePCIID_Intel_HD_Graphics.kext then i used Fake ID for IntelGFX (0x19168086) and put 0x19160000 for the ig-platform-id

dont forget to reboot with an invalid platform id (0x12345678)
run sudo kext cache -u /
then reboot with the valid id (0x19160000)

My laptop is Dell Inspiron 7370 with intel's CPU 8250U (w/ UHD 620). I did the above: installing kexts and boot with platform id 0x12345678 - kextcache - reboot with 0x1916000, but still cannot boot once I put IntelGFX (0x19168086) and platform id 0x19160000.

Do you have any idea about what specific mistake one could possibly make during these steps? Thanks!

Hi just wondered if you can Link the kexts and config file you used to get your intel UHD 620 graphics working?
As I can't find all of the kexts or the ones I'm using don't work.
Thanks
