Get [solved] and set [unsolved] DVMT Variable Phoenix BIOS

[Mike7-7-7]

At Phoenix BIOS (Fujitsu Lifebook) there is no option to set DVMT pre-allocated memory and no one of these Applications works at Win10 to get them:
- WinPhlash 1.7.16
- Universal BIOS Toolkit 2.0
- WinFlash 3.2.5
- Secure WinFlash 2.0.3.4

Does anyone know another way to get the variable to set it at EFI-Shell?

P.S.: Seems not to be 0x432, because this variable I have tried to set without success.

There are some guides linked from the FAQ.

Unfortunately I do not have a variable at linux with efivar to unlock hidden or advanced pages in BIOS.
Efivar also does not show something about DVMT.
Many information are not applicable for Haswell.

You have to do a BIOS IFR extract.

You can try using a tool like "BIOS backup" or something to dump your current BIOS in your laptop.
Try 'Google' it.

On Windows7 I reached backing up the BIOS now ...
Unfortunately there is no module called "Setup" and all Modules including the word "setup" does not have the DVMT-Variables.

(I extracted the PE32 imge Bodies as text-files and searched the strings.)

Attached there is my BIOS-Backup - deleted -
May someone please check if there are DVMT-Variables?

Sorry, but I can't extract the PE32+ file.
It shows "UNKNOWN" when trying to extract by using IFR Extractor.

Which Module did You try?

Which Module did You try?

I'm just using Phoenixtool to extract the ROMs.
First I didn't found any file which title is 'FE32', so I tried to extract the ROM file which the same UUID contains PE32+.
But IFR can't extract it. Program can't recognize the type of image.
