Hello,
there will be plenty of users looking for some way to enable using AMD-V feature on Acer Ex- series notebooks, if virtualization software vendors or Acer will not take an action soon. I have bought one of these and I was very surprised, that even Windows 10 reported virtualization features as supported, but disabled in firmware. As I can see so far, from all sites I have searched through, it has something to do with the way, how softwares like VirtualBox are detecting virtualization support. On the AMD site I have found, that from some version AMD-V feature should be accessible no matter of BIOS/EFI settings state. But obviously some software isn't ready for change yet and instead of detecting AMD-V feature directly, they still use NVRAM state bit. I have found this mod howto:
http://www.cnx-software.com/2015/03/22/a...p-utility/ , but I was unable to write changes to NVRAM. Tried few ways to do it (mounted efivars and editing files directly under root account, used newer efivar aproach), but even efivar -f doesn't changed stored value Setup-a04a27f4-df00-4d42-b552-39411302113d.
So does anybody know other posible way to write NVRAM? Found some Python and C libraries for it, but first of programming own tool, I want to be sure that it's not like reinventing wheel. I think, there should be an tool allready programmed.
