You need to put the vars_mod.txt file in the folder with the H2OUVE.exe file and execute the following command in an administrative command prompt in that folder: H2OUVE.exe -sv vars_mod.txt
H2OUVE will update the NVRAM area of the BIOS and after a reboot the new settings should be active.
Unfortunately there's no setting in the BIOS that allows unlocking of the advanced tab.
However, with disabled SMM Code Lock it might be possible to flash a modded BIOS using flashrom on Linux (there's no suitable Windows flasher for AMD Insyde systems), but I don't have enough knowledge regarding this matter.
Thanks. I was trying to figure out the mapping from the acer reference file to the vars.txt...not seeing it yet.
Is everything there under the setup block in the vars file?
Applied, confirmed amd-v is now enabled! Fantastic, now I've got the laptop I thought acer sold me....thanks mclarke2355 and Dudu2002

I'm glad that it worked properly!
Yes, all the current settings are saved in the setup block of the vars file. It's the only block that we need to change.
The variable tells you at which position the setting is saved (e.g. SVM Support has the variable 0xEE, so its setting is located at position EE (Hexadecimal) in the setup block).
So, if you want to change something else, you just need to look up its variable in the EFI-table and then change the according value in the setup block of the vars file to the desired one.
