Once you are in the BIOS, you need to enable virtualisation. This may vary between PC models and brands, but common keys are : F2, escape or del. If your processor supports virtualisation, then you can boost the performance of your emulator ! To do this, you need to restart your computer and access your BIOS at startup:
