bios中没有这个选项， 我看了网上别人的办法。是这样弄的：

    下载虚拟软驱、SYMCMOS，把SYMCMOS.EXE放入虚拟映像，安装虚拟软驱
启动到DOS环境
    运行 SYMCMOS -LCMOS.TXT,编辑CMOS.TXT,比如联想3000 G430A-TSI(我把CPU换成了T7250,BIOS版本1.13)编辑REG35A的[0000]->[0001]
    然后运行 SYMCMOS -uCMOS.TXT
    重新启动至windows,用SecurAble测试一下，会变成LOCKED ON。

    我也这样弄了，最后symcmos -v2 -lvt.txt 出来的vt.txt不知道改哪个reg，那位大大指点下啊。网上都说在02xx-03xx之间，怎么分析啊。万分感谢
