Your bios chip is rewrite protected
Bios mod can be flashed using SPI-programmer+SOIC8 clip only

Ok, I can help you.
If you upload the variable dump from step 1 of the guide, I can modify it.

Also, here's the EFI-table of your BIOS that shows which settings are available: https://drive.google.com/file/d/0B4NHIBM...JkeG8/view

Ok, here you go: https://drive.google.com/file/d/0B4NHIBM...RxN0E/view
I've included two files: one with 96MB DVMT and one with 128MB DVMT.
Choose the one you want and continue with step 3 of the guide.
