[Guide] Alternative to the minStolenSize patch with 32mb DVMT-prealloc

what is the suitable kext for high sierra intelhd620 kabylake? is it AppleIntelKBLGraphics ? it looks like it is missing in my sle can i get it somewhere?

From where did you download macOS?
On what hardware did you create your USB installer?
 
I have a question Whic one patch are better minStolenSize patch with 32mb DVMT-prealloc or
Disable minStolenSize less or equal fStolenMemorySize assertion, 10.13.2/3 (credit PMHeart

Your choice. Test both, if you wish, to see which strategy works best for your hardware.
 
Is it possible that computers that don't have the DVMT-prealloc setting in BIOS actually do have it but it's hidden? If the BIOS uses UEFI then the setting might be listed in the IFR which can be extracted using Universal IFR Extractor which includes ifrextract which can be compiled for macOS and is a command line tool so it can be scripted. There are some compatibility issues I needed to fix to make it work with the macOS compiler. https://github.com/LongSoft/Universal-IFR-Extractor/issues/4

The following post describes a method to change the DVMT prealloc setting if the necessary information for it's location is in the IFR:
https://www.tonymacx86.com/threads/guide-intel-hd-graphics-5500-on-os-x-yosemite-10-10-3.162062/

Maybe an EFI or Clover command could be created to find all the IFR information (if it's located in more than one module). Maybe Clover could get such information (either from the IFR or from config settings) to change any or specific settings. The BIOS for my computer lists around 3000 different settings in the IFR...

It would be interesting to get a list of computers that don't have the DVMT-prealloc setting available to the user, and then see if any of them have the setting information hidden in the IFR.

Most desktops can change DVMT-prealloc in BIOS (and that is the preferred thing to do)...

Yes, but Dell'BIOS don't provide that option. :crazy:
