IMPORTANT!: Contrary to many of the guides you will read, Windows is NOT a valid way to determine what DVMT-prealloc is set to. There is no correlation, especially with Windows 10.

Follow the Clover guide linked from the FAQ.

Pay attention the Skylake info in the FAQ. It is important.

You can try the minStolenSize patch, but it will likely not be stable.

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

Mobo: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

Note: When specifying your bootloader, if using Clover legacy, please be sure to specify "Clover legacy"). Specifying "Clover" will be assumed as "Clover UEFI"

minStolenSize patch not recommended. Best to purchase a laptop where setting DVMT-prealloc is in BIOS, and if not, is at least possible via Linux efivars or setup_var in UEFI shell.

But i dont search linux efivar use.
Exist only setup_var method.
Already i tried to command setup_var.
I cant change value. Because bios is locked
So i want to use linux efivar.
