I never updated my bios , was already updated from the guy I got the laptop , but is the same bios used from my service tag , should I maybe flash this bios first ?

There are tools you can use to backup your current BIOS. Then you can do IFR extract from that...

that would be smart , what tool should I be looking for ?

Also , using the tool directly on the .exe of the bios , should that have something to say ? Cause in guide is to extract it , and use a .fn file from it , but I have no such option to extract the .exe , forcing it to winrar says there is no archives in the file .

 

[norocel]

could you please check if can be extracted ? and how should I do it? here is the Bios .

You will find out when you do the IFR extract and attempt to set DVMT-prealloc with setup_var (or setup_var2) in the special UEFI shell.

what is the diffrence from var or var2? But would AMI bios accept such changes ?
Wondering what are the chances to mess it up .

No idea. But some have reported success with setup_var2 where setup_var failed.
I'm sure you could obtain the source code to that shell and analyze...

But would AMI bios accept such changes ?

I cannot predict the future.

Changing options not intended to be changed always a risk.
If you don't want to risk it, why not use the minStolenSize patch?
