Can't use setup_var (offset out of range)

[OmarRod1314]

I'm trying to reduce the Max TOLUD of my Lenovo M72e (Ivy) BIOS so I can get 2 GB worth of PCIE address bar for my graphics card... Unfortunately, even with the identified 0x2D1 offset in my GUID file and the "1 GB" 0x3 value from there, I keep getting this error in the end of the sequence. No changes were made as I still had 256 MB of ReBar like before so... What's left to do?

Here's the file just in case, extracted with Universal-IFR-Extractor and UEFITool beforehand. The command I used is "setup_var 0x2D1 0x3" and the setup_var_3 version of it. Same results.

Can you try setup_var.efi for better error information?
The IFR info does show 0x2D1 in Setup, so the command should be right.

Do I need to use the same command? And if the case, can I just reset the CMOS or load BIOS defaults to revert these changes? Just making sure before changing this out.

The command is changed a little, but the README in setup_var.efi describes how to transform the grub commands to the newly ones.
Clearing CMOS usually will reset changes to default, as long as only operating with varstores used to store settings (i.e. shown in IFR txt). But it's very implementation-dependent and thus doesn't have a definite answer.

I tried to boot this one but when I choose my device it just doesn't and boots the system instead.

That tool needs to be used in a UEFI shell for showing results.

What's that? I can't just put it into a Windows install efi folder like the another?

You need to boot UEFI shell, and use the setup_var.efi inside the shell.
