    I have a Toshiba Satellite C655D-S5302, with AMD-V support or was anyway. I had updated my bios to Insyde Version 1.80 which had removed the option for the AMD-V. I just noticed this and I want to install Mac OS X Mountain Lion VMware image from the souldevteam website. It said "VMware cannot access this Machine because your computer does not support this option, or is disabled. I checked in my bios and It was there before the update. Strangely it disappeared in the latest update. Is there an way to modify or downgrade at all to a previous version that I had it, I really would like to know. Also I am I the only one who has this problem If not that's okay, but if anyone found a fix for this or there is a safe way to have this option back on the bios please let me know. I tried to reinstall VMware but it still could not find it, I have looked at other ways such as bios mods but I am new to the whole bios options. Please Let me know if there's a workaround or hack for this I am running VMware Workstation 10 but not sure what version. However I am a registered developer for Apple and Microsoft and would like to get this working again so I can test my apps and software again.

    Any help is greatly appreciated. Thanks Also Have a Happy New-year.

    did you go into bios after flash and press "Load Setup Default" or something similar.
    then reboot and check if the feature is now available in the bios?

    I suppose if you backed-up your old BIOS while flashing the new one you could reflash w/ the old one.

    it supports VT / Virtualization technology but does not mention if it supports
    vt-x or vt-d or both

    here is some info
    [h=3]AMD[/h] Segmentation support is missing from the initial AMD64 processors (that is, revision C and earlier) while running in long mode. As a result, AMD64 processors prior to revision D do not have an efficient mechanism for isolating the virtual machine monitor from 64-bit guest operating systems. A limited form of segmentation was reintroduced in long mode, in revision D AMD64 processors. As a result, AMD64 processors must be revision D or later to run 64-bit guest operating systems.
    Note: Because AMD Opteron and Turion processors do not ship in revision D, AMD Opteron and Turion 64 processors must be revision E or later to run 64-bit guest operating systems.
    When reading AMD's documentation, revisions may be given in decimal format (rather than hexadecimal format). For example, Revision F may also be referred to as Revision 15.

    Do you have an original Turion x64 or the later Turion II (which is actually closer to the Phenom II/Athlon II).

    I have two HP notebooks with AMD CPUs - the one with the Turion x64 does NOT support Hyper-V, but the Turion II-powered version does (in fact, it has Server 2016 10074 on it for use as a mobile developer platform).

    The difference is (of course) AMD-V (the AMD version of SLAT).

    The quirkier part is that Windows Server 2016 10074 installed fine - Hyper-V and all; however, Windows 10 Pro or Enterprise later than this same build will NOT run with Hyper-V enabled in the BIOS - all attempts to install it as a feature in those builds fail or lead to black-screen failure/instant reboot heck.
