Keep in mind:
- DVMT-prealloc must be set correctly (both of these ig-platform-ids require 64mb)
- once you change DVMT-prealloc, you must re-extract/re-patch ACPI
- each of these ig-platform-id values requires different LMAX settings (backlight control), 0x04260000 requires 0x1499, 0x0d260007 requires 0x7a1

No DVMT-prealloc option in BIOS. Only a "Total Graphics Memory" with 256MB or 512MB.
Should i try this guide even if my platform is Haskell:
https://www.tonymacx86.com/threads/...lensize-patch-with-32mb-dvmt-prealloc.221506/

With no ability to change the DVMT-prealloc, you would need to add an appropriate patch to change it to 32mb.
You can use the guide you mention as clues for what you need to do.
Also refer to the existing patches in my repo (linked from my Clover guide) for Haswell.

i shouldn't delete the original 9MB patch, it's still needed.
Solved.

Yes, typically it is needed, which is why it is default in all Haswell plists linked from my Clover guide.
