How to find the right side in the value table for editing in mod.txt?

I have an Acer E5 553 13AB laptop with an AMD A12 9700P APU that I would like help with.
I'd like to know if there are hidden options to be unlocked in this BIOS such as disabling PSP, fan speed control, Virtualization (The chip actually supports it), and overclocking, and if not, is there a way to add them?
It's a pain to enable VT through windows and thermal throttling is horrible.
Here's the link to the BIOS. I am currently using V 1.19 as V 1.31 caused issues and I had to revert to this one.

Although, I figured out how to enable virtualization on my laptop by reading through this thread, so I will share what I did in hopes that it helps others like yourself.
For reference, my laptop specs:
Aspire E5-553G-1986
Windows 10 (Version 1703)
AMD A12-9700P Processor
8GB RAM
BIOS version 1.19
Step 1: Download this tool: https://drive.google.com/file/d/0B4NHIBM...RtQXM/view
Step 2: Extract the tool into a new folder on your desktop. Name it BIOS.
Step 3: Open Windows start menu, type in "cmd", right click "cmd" and click on "Run as Administrator".
Step 4: In command prompt, type in "cd " and then the directory to your file on the desktop. You can find this by right clicking the folder, clicking on properties and copying the location. Go back into the command prompt and press CTRL and V at the same time on your keyboard to paste it. Then add "\BIOS" and press ENTER. For example:
Code:
cd C:\Users\Ryan\Desktop\BIOS
Step 5: Type in "H2OUVE.exe -gv vars.txt" and press ENTER.
Step 6: Open the newly created vars.txt in the BIOS folder with notepad and press CTRL and F at the same time on your keyboard and search for "Setup". It should look something like this (the numbers will probably be different - note that it may take a few searches, the file is huge):
Step 9: Save your change as a new file called "vars_mod.txt".
Step 10: In the command prompt window (refer to Step 3-4) type "H2OUVE.exe -sv vars_mod.txt".
Step 11: Restart your computer when the command prompt finishes execution (should take only a few seconds).
Step 12: Let Windows do its thing and fully shut down. For me, this took longer than it normally did, just a heads up. If your screen turns black and does not restart, then you can manually power it back up.
Step 13: Open task manager, click "more details", open the "Performance" tab and check that virtualization is enabled. If it is, you're good to go. If not, you either changed the wrong value or something went wrong. If so, then open up command prompt again as admin (Step 3-4), go to your new file and then type "H2OUVE.exe -sv vars.txt" and restart your computer again. This should revert whatever change you did.
As a side note, I saw something about this mod cutting the usable RAM in half... not really sure what they were talking about, but I did not experience this issue using the above steps.
As a second side note, it appears that if you upgrade your BIOS you will lose your virtualization setting. You will have to manually enable it again using the above method to make a new vars.txt and new vars_mod.txt.
Lastly, I made an account on this site to specifically thank mclarkke2355 and others on this thread that allowed me to force enable AMD virtualization on my laptop so I can finally use it for college. Hopefully my instruction set helps others that view this thread in the future.
After hours and hours of searching, researching, broken h2ouve.exe downloads, etc... This worked for me! Thank you so very much Ryan.

HI there, I don´t know if every laptop needs an specific file to modify the bios and enable VT and V-memory. Mine is Aspire E5 553-1786. Serial NXGESAL00261806470****. Bios v1.31. i don´t know what do,. i need to enable VT and how. please if someone already did this need your help.

the flashing of the modded BIOS might not work because the recovery checks the signature of the BIOS file.
However, you might be able to enable AMD-V using this method (needs to be adapted): http://www.geektech.co.nz/how-to-unlock-...enovo-y700
This method requires Windows as a system as the necessary tool is only available for Windows.
First, you will need the tool: https://drive.google.com/file/d/0B4NHIBM...RtQXM/view
Extract the archive and go to the folder with the extracted files.
Then, you need to open an administrative command prompt in that folder (google it if you don't know how).
Execute the command from step 1 of the linked guide in that command prompt (H2OUVE.exe -gv vars.txt).
After that, you'll have the file "vars.txt" in that folder.
You need to upload this file, so that I can make the change.
For reference, here's the EFI-table with available settings for this notebook: https://drive.google.com/open?id=0B4NHIB...WI4LW14bE0
And here's the setting that needs to be changed:

Hi Mclarke,
My laptop is Acer E5-553-T4PT model and my OS is Windows 10 Home. Please enable virtualization for the laptop.
