Hi,
Noob here. Found this thread and it's awesome, so thanks!
I'm trying to change the DVMT allocation and am a bit puzzled on how to proceed. I'm trying to do this with BIOS 2.5.1 without going through the rigamarole of downgrading it. I extracted the BIOS using Universal Backup Kit 2.0, found and extracted the DXE Core to a txt file, and found the DVMT settings. What I DON'T see, is a setting for anything above 64M. Was the BIOS extraction truncated or something? Am I missing something or misinterpreting something?
Edit: Oh, I should say that I have the QHD screen. Couldn't find the FHD version...
Thanks for any help or insight you can provide!
Here's what I found:
