Dear RehabMan,
thanks for your excellent guides!
I want to install Mojave on my Elitebook 820 G3 (Intel HD Graphics 520) according to your other guide (currently running Sierra). But there is one point that's not fully clear to me concerning DVMT and config.plist patches. You wrote:
If your laptop has DVMT-prealloc set as required (64MB or 128MB), you should disable or remove the 32MB patch. You will find such patches in config.plist/Devices/Properties/PciRoot(0)/Pci(0x02,0).
My BIOS settings include:
Advanced => Built-In Device Options => Video memory size = 64 MB
So I can disable the 32 MB patch. But what entries have to be removed?
I'm viewing your config_HD515_520_530_540.plist using Clover Configurator Pro (just found a note from RehabMan: DO NOT edit your config.plist with Clover Configurator) and also in vim. To make this posting simple I'll post the xml code, not a screenshot:
<key># DVMT-prealloc</key>
<string>32MB BIOS, 19MB framebuffer, 9MB cursor bytes (credit RehabMan)</string>
<key>framebuffer-patch-enable</key>
<integer>1</integer>
<key>framebuffer-stolenmem</key>
<data>AAAwAQ==</data>
<key>framebuffer-fbmem</key>
<data>AACQAA==</data>
Clover Configurator of course shows four equivalent key value pairs. Now the question:
Do I have to remove all four of those key value pairs? Or is it sufficient to change "framebuffer-patch-enable" to 0? Or do I have to remove even more entries in the config.plist?
Your previous config.plist I used had a different format that was clear to me. But I'd like to use your updated config.plist.
I would highly appreciate any hints about what to change in the config.plist!
Thanks a lot!

Edit:
After some more googleing I found two postings that probably answer my above question, so I want to share those links:
[Guide] Alternative to the minStolenSize patch with 32mb DVMT-prealloc
[Guide] Intel Framebuffer patching using WhateverGreen
From those posts I conclude (but not 100% sure yet - so no guarantee) that all of the above xml code can be deleted to remove the DVMT-prealloc patch. In a plist-editor this would mean to remove the four keys:
- # DVMT-prealloc
- framebuffer-patch-enable
- framebuffer-stolenmem
- framebuffer-fbmem
They are found in RehabMans config.plist (as of June 2019) under: config.plist/Devices/Properties/PciRoot(0)/Pci(0x02,0)
