如何用程序实现“启用、禁用、修改CMOS的开机密码?”
 
我想CMOS里面的功能就是所有了,如果你可以在CMOS里面的菜单做到,
那你就可以去完成。当然了,如果你可以更改CMOS里面的指令,那就是
另外一回事了。
 
CJF:我在这里提这个问题,肯定是想用Delphi代码来实现,你说呢?
 
设计了一个CMOS .PAS的程序,它可以将CMOS内存中的信息直接写入文件,也可以把文件中
的信息写入CMOS 内存,同时可以对CMOS内存中的信息进行编辑修改,并重新写回CMOS内存。
不仅解决了没有SETUP程序的计算机在加电时不能设置CMOS内存的问题,同时解决了CMOS信息
的保存和恢复问题.

该程序的使用很简单,在DOS提示符下打CMOS,即显示该程序的使用方法,具体使用
方法是:
CMOS [/开关]
开关有3个:
R --- 读取CMOS内存信息,并将其存入CMOS.DAT的文件,共占64个字节。
W --- 从CMOS.DAT中读取信息,并将其写入CMOS内存。&127;注意这样写入的CMOS信息,其
时间和日期是不正确的,写完之后应当用DOS命令DATE和TIME&127;设置正确的日期和时间

M --- 从CMOS中读取当前信息,进行修改,然后将其写入CMOS内存和CMOS.DAT的文件。

其体情况我还要测试。先感谢tyn[:)]
 
修改我想倒是可以的(修改CMOS的数据),启用、禁用我就不明白你要的是怎样一种情形了。
 
启用、禁用指的是开机密码。
 
什么意思?指使用和不使用开机密码?即开机时要输入密码,或者不需要?
 
我在D7下无法编译!!!
出现如下错误提示:
[Error] Project2.dpr(90): Operand size mismatch
[Error] Project2.dpr(111): Operand size mismatch
[Error] Project2.dpr(193): Undeclared identifier: 'CMOSRe'

你能给我传过你的 CMOS。PAS 这个文件吗??谢谢!!
