常有一些微机的CMOS配置被人无意或恶意改动,或受到病毒攻击而将密码改动导致机器不能正常工作。而用户由于没有密码又不能启动setup程序重新配置,一般只能是拆开机器切断充电电池对CMOS存贮器供电以使其丟失信息。但此种方法非常麻烦,原有信息会全部丢失,许多普通用户更是对拆机望而却步。也有用测试软件(如QAplus)修改的,但其修改内容范围非常小,往往不能满足要求。 Often some CMOS configuration of the PC has been unintentional or malicious changes, or by virus attacks and password changes lead to the machine does not work. The user can not start the setup program because there is no password to reconfigure, the general can only be opened to cut off the battery charge to the CMOS memory CMOS memory to lose information. However, this method is very troublesome, the original information will be lost, many ordinary users is even more prohibitive on disassemble. There are also test software (such as QAplus) modified, but the scope of the amendment is very small, often can not meet the requirements.
