Thank you for the response and the vars_mod.txt file
... followed instructions about loading modded vars.txt
using Win 10.. PowerShell as admin..
rebooted about 3 times to both Wind0lt & Linux
no new options available in BIOS,
no VT-X enabled
there were a bunch of failed loads.
posting 3 files
1. vars.txt
2. vars_modded.txt
3. vars_load-errors.txt

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:
0x1C40B Setting: SVM support, Variable: 0xEE {05 91 54 02 55 02 54 00 34 12 EE 00 00 10 00 01 00}
0x1C41C Option: Disabled, Value: 0x0 (default) {09 07 27 00 10 00 00}
0x1C423 Option: Enabled, Value: 0x1 {09 07 28 00 00 00 01}
but here is my vars.txt my laptop is an Acer E5-553G-F79R. can you help me? I need AMD-V for school assignment

I have a copy of your vars_mod.txt file but things seem to be sequentially different.
Hi!
Your mod vars.txt i sent you via PM.
Can you also help me? Will be very glad if you did. Please i need AMD-V for Vbox and college assignments!!

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.
Just wanted to say this tutorial was very well written, thank you im_ryan. I would like to ask a question about how that bit was known. Here is the table information:
"Form Set: Advanced" implies that I'm looking for the "Setup" section and then "SVM support, Variable, 0xEE" tells me where in that block this is pointing which, in dec is 238 or the 14th line or line "000000E0" on the example below:

I have the attached the var.txt file that I need updated to allow my acer laptop to enable the AMD-V option so I can use virtual box in 64 mode. Thanks in advance.
