So one of the bytes gets updated, then apply to running system?
Is it possible to enable the advanced tab in the bios this way too?
Thanks,

Ok, here's the file with AMD-V enabled and SMM Code Lock disabled: https://drive.google.com/file/d/0B4NHIBM...JoSU0/view

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.
 can you help me here a little? i run ubuntu, would like to try flashing. but i need the unlock over vars file first?

Hello mclarke2355, first, thank you SO MUCH for this effort, it's incredible Acer just sold a bold thing without one of the most important features in a processor... but well, their loss...

I followed your instructions for creating a vars.txt file, and I'm uploading it here, in hopes you can help me enable AMD-V in my system (I only need that). I'm posting my whole specs in case you need my complete information:

Laptop: Aspire E5-553-1786
OS: Windows 10 64 Bit Home Build 1607
Bios Version: 1.13
16 Gigs RAM (15.5 available)
AMD A12 APU 9700P
Radeon R7 Graphics (512 MB)
Currently, AMD-V is disabled, task manager says so, and VirtualBox doesn't let me install 64bit OSes, VmWare Player cannot use AMD-V for faster operations.

I'm uploading my vars.txt for you to check it.
.txt   vars.txt (Size: 110.08 KB / Downloads: 11)

I have a little doubt tho, will this process change any other BIOS settings in the laptop? (specially messing with the hardware reserved memory, I want it like it is currently) Will this revert the fix this version of BIOS has regarding display banding? (ver 1.13 fixes a severe banding older revision was having, right now I have no issues) If I have any trouble with this, is there anything I can do to restore it to a previous state?

Sorry to pester you with this questions, but I wanna be sure before patching my system... it was an epic victory to force Acer to fix my problems with the display...

Thanks in advance for your ENORMOUS help.

See ya!! Big Grin

If you still need AMD-V enabled, follow the instructions in this post and upload the vars.txt file: https://www.bios-mods.com/forum/Thread-R...#pid127706

Hi,
here's your modded vars-file with AMD-V enabled and SMM Code Lock disabled: https://drive.google.com/file/d/0B4NHIBM...RTU2c/view

Before you try flashrom, you should apply the modded vars-file first as the disabled SMM Code Lock is important.

You need to put the vars_mod_--seb--.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_--seb--.txt
H2OUVE will update the NVRAM area of the BIOS and after a reboot the new setting should be active.

I'll write more regarding flashrom later as I don't have much time right now.

Hi,
here's your modded vars-file with AMD-V enabled: https://drive.google.com/file/d/0B4NHIBM...A5SXM/view

You need to put the vars_mod_FerchogtX.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_FerchogtX.txt
H2OUVE will update the NVRAM area of the BIOS and after a reboot the new setting should be active.

This method will only enable AMD-V and not mess with any of the other settings of your BIOS.
In case you want to revert to default, you can go back to default with the following command:
H2OUVE.exe -sv vars.txt
Using the reset to defaults option in the BIOS would work, too.

H2OUVE.exe -sv vars_mod_yoshh1999.txt
H2OUVE will update the NVRAM area of the BIOS and after a reboot the new setting should be active.

Hello, I found this thread while searching for ways to update/fix this laptop I bought. I've followed your instructions and attached my vars.txt file. *edit - I only need AMD-V enabled so that virtualization will work.

Still trying to figure out which bits to change but I have no idea.

Aplied your file... AND THIS IS JUST AMAZING! Thank you so much for this, you have no idea how I appreciate your help and you being able to fix this setting for our systems. This worked wonders! Now I can use AMD-V for WMware, and the virtual machines work blazingly fast!
Thank you, THANK YOU so much for this, you are an angel! Angel
Cya!  Big Grin

Proof:
   
   
   

Virtualizacion: Habilitada = Virtualization: Enabled

Ahh, also, even if you reboot your system or shut it down, the status remains the same, at least for me, it always says enabled, as well as in my software.

Again, thanks a bunch!!!!!! Big Grin

After looking further into flashrom, I have to say that it is probably too risky here.
There's a good chance it would brick your laptop: https://www.flashrom.org/Laptops
If you want to use it anyway, keep the risks in mind and always create a proper dump of the chip first!
Links to get started on flashrom: https://www.flashrom.org/Board_Testing_HOWTO https://wiki.archlinux.org/index.php/Fla...x#Flashrom

The safer alternative would be to use H2OUVE to change the settings you want.
It's not as comfortable as making the changes directly in the BIOS, but it is also usable for all settings.
This file shows you which settings are available for this notebook: https://drive.google.com/open?id=0B4NHIB...WI4LW14bE0
Tell me which settings you want to have changed and I will modify them for you.

Hey mclarke2355!!

I have a little doubt! One person with the same model of my laptop tried the BIOS update from acer site to fix their display banding problems... but sadly, besides having that fixed, they get their RAM cut half (7.45 GB instead if 15.5 to use) and the processor doesn't seem to achieve the correct speed (3.40 GHz with turbo instead of the max 2.50) Is there any chance we can change this settings in the Bios so he can get back the normal behavior of the RAM and processor?

If so, I assume you need the vars.txt file, correct? Ill ask the user to generate one so you can evaluate his problem, and post back to you.

Thanks in advance Big Grin
