You can also try setup_var2. But your BIOS has likely locked the settings, which means you won't be able to change them.

You can use the minStolenSize patch if you can't change DVMT-prealloc.


how to change minStolenSize please help

Use setup_var to determine current DVMT-prealloc value.
Windows is not reliable to determine DVMT-prealloc.

Dear Mr. Rehabman

My Laptop is Lenovo Zhaoyang E40-80, the bios is insydeh20.
CPU:Intel i5-5200U;
Graphics:Intel HD 5500 (1366*768)
Eth: Realtek 8168/8111
SoundCard: ALC233

It's installed the OSX 10.12.3 use for UniBeast 7.0.1. The keyboard & Ether is perfect, but the Graphics isn't performance,The VRAM is 4MB. I set "setup_var2 0x18C 0x4" like picture #1, "setup_var 0x18C 0x01" isn't change.
The Method isn't fit OSX 10.12.3?

Attach IFR BIOS extract.

Note: I don't know why the output of setup_var2 shows two different values for the index 0x18c.
