    Default BIOS Setting: Should I disable CPU Secure Virtual Machine Mode?

    I would like your help regarding this:
    When I ventured into BIOS setting to disable the onboard network controller, under CPU setting I happened to see something like this:
    Secure Virtual Machine Mode: Enabled.
    I do not know what it is and there is not much info about it on Google either except:
    http://www.mimuw.edu.pl/~vincent/lec...cification.pdf
    which stated that:
    "AMD security and virtual machine (SVM) architecture,
    codenamed “Pacifica,” is designed to provide enterprise-class
    server virtualization software technology that facilitates
    virtualization development and deployment. An SVM enabled
    virtual machine architecture should provide hardware
    resources that allow a single machine to run multiple operating
    systems efficiently, while maintaining secure, resource-
    guaranteed isolation."
    My CPU:
    AMD Athlon 64 X2 4200+
    Motherboard Model:ASUSTeK Computer INC. M2N-MX SE Plus
    Motherboard Chipset: nVidia nForce 6100-405/430

    I do not run dual boot or multiple OSes on my pc, nor using any virtual pc software.
    Do you think it is safe to disable it?
    Will disable it render my pc unbootable?
    Sorry for sounding too cautious but due to my ignorance with BIOS settings I dare not
    change it without asking you first.
    My pc is stable at the moment, but I wonder if I could improve cpu performance if I disable the mentioned feature.
    Thanks and Regards,

    It will make no difference either way. Intel also use a similar technology (Intel VT). It allows the CPU to be proportioned a lot more effectively without 'toe treading' when resourcing Virtual Machines.

    Welcome to the age of virtualisation
