    Wondering how lucky we could get

    Within the Setup variable array, offset 0xdddd contains the User Access Level byte.
    The values for User Access Level are:
    0x00 - View Only Item
    0x01 - No Access
    0x02 - View Only
    0x03 - Limited
    0x04 - Full

    This User Access Level byte is checked on almost every EFI configuration value available to display in the Setup utility. Changing it from the default 0x02 - View Only value to 0x04 - Full Access might allow more EFI values to be viewed and/or changed, but I'm too tired to attempt that tonight. (I'm happy just to have gotten this far in one day.)

    The image attached below is the output of the vtenable.py script. The highlighted bytes show the VT Support and User Access Level flags.

    VT was successfully enabled

    This morning I backed up the installed factory BIOS and flashed the patched BIOS. Unfortunately the default InsydeFlash options didn't flash the updated Setup data values into the BIOS. I enabled the Options dialog in platform.ini and re-ran the flash process. This time I selected to flash ALL BIOS segments and after rebooting VT is enabled :D in the Locked On state. Attached below are screen shots from the GRC SecurAble utility showing the VT state disabled before and enabled after the complete BIOS flash.

    Do you still have the files(*.py, *.fd) used to enable VT-x? I have an identical laptop(Acer Aspite 5315 ICL50, Insyde Bios v1.34) and I want to do some comparative tests.

    I am a malware analyst and I use VMware to study viruses, worms, trojans, spyware, etc.
    VT enables almost real-time execution.

    VT enable on Aspire 4925 please HELP

    I've got an Acer 4925 Aspire with a T7500 proc. I've gone inside the BIOS which seems the same as most of the type and versions mentioned here - InsydeH2O ver 3.5.

    Like most I cannot access the advanced menu features or even the VT enable setting. I've read the posts here and by marcansoft and some others but none of those have mentioned a universal Aspire solution.

    I'd like to get the full feature set of my Aspire 4925 BIOS. Can anyone help please?:help2:

    Thanks.


    Aspire BIOS name: AL90_122.fd (DOS flashing)
    JAL90122.EXE (windows)

    Could this or a similar method be used to activate virtualization on my NE72214u. GRS Securable says that my AMD Quad-core A4-5000 offer hardware support for virtualization. Could I get some help?:confused:

    Depending on the CPU/etc., enabling virtualization will enable (at minimum) either the basic VT-x (Intel Core series and AMD equivalents of the same era) or Hyper-V (superset of VT-x; applies to Core i-series (all generations), Intel 4th-generation (LGA1150) down to Pentium-G32xx, and AMD desktop and mobile CPUs and APUs back to and including Turion II).

    No - I didn't stutter when I mentioned either APUs or the Turion II (which said APUs replaced); just to my right I have an HP Pavilion dv4 2045dx that I have reconfigured into a mobile development platform via the tag-team of Windows Server 2016 (Technical Preview 2) and Visual Studio Community 2015 RC. For some reason, later versions of Windows 10 have issues with Hyper-V, while Windows Server 2016 (which gained the SLAT requirement) installed sans quibbles - hence the use (once again) of server OS as workstation OS (something I did with Server 2012R2 on my desktop before 10 came along).
