[RehabMan]

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.

If your BIOS locks the variables, you need to use the minStolenSize patch.

<key>Name</key>
<string>AppleIntelBDWGraphicsFramebuffer</string>
<key>Replace</key>
<data>

If you want to use a patch from another source, it is up to you to verify the correctness.

DSDT is not involved.
The patch must be enabled. Read the guide. Carefully.
