    It may work but you need to read all you can about Editing CMOS Settings in Memory, I have never seen it done but good luck.
    You would have to set it up so that memory setting was edited every time the PC Boots.

    Why not just set the menu item to Normal in ModBin and save it then flash the BIOS with the new menu item shown ????

    Bacause I'm a bit scared for a badflash. This is our only pc at home except for an old crappy one without internet connection (upt is port borken), so if I brick it everyone will be really angry at me... And why would I need to change it on every bootup? Isn't the cmos only cleared when you take out the mainboard batery or when you load setup defaults?

    I don't need to change the setting in memory at every bootup, neither I have to flash the bios.
    If I use symcmos to make another dump of the cmos then I have to find where the option is in that dump (disassembling the bios). The I use symcmos to place the edited cmos dump back to the cmos chip. No bios flashing and nothing needed every bootup.

    But the guide is for intel cpus ans I've amd, so I don't know after which values I have to search in the bios.

    I don't think it actually works without the BIOS Settings getting changed.
    It looks like by using symcmos, you are technically Flashing (clearing and Rewriting) the CMOS Settings of the BIOS.
    I think it would be safer and easier to just enable the setting in ModBin.
    Just be sure to read the ModBin Guide linked in the Bios Tools thread.

    OK what's the risk for a bad flash when I make a dos cd with award flash tool and moddid bin file, and disconnect all hardware except for keyboard and screen?
    And is there any chance the bios gets corrupted because the bin gets corrupted during modding?

    My bios screen shows "Pheonix technologies AWARD 6.00GP", so deos it matter what tools I use (award or phoenix)?

    I think I'm just leaving it as it is, afterall I've heard that amd-v and intel vt don't bring very much performance improvement over software virtualisation.
