Hard disk serial number
Question
Is there anyone who knows how to obtain the hard disk serial number?
Answer
I have an unit to get the Hd Name and the Hd Serial number for Borland
Pascal 7.0. I don't know if it's working with Delphi and the other thing is
that it is in dutch and I don't have time to translate it in englisch. Mayby
you can use it, otherwise drop it out of the window.
Unit HardDisk;

//CPUID：
用CPUID指令，首先你可以确定你用的CPU是Intel的。
然后执行：
MOV EAX,01H
CPUID
如果返回的EDX中，低18位为1，那么这个CPU就是支持序列号的。
此时EAX就是序列号的高32位。这32位对同一型号的CPU是一样的。
再执行：
MOV EAX,03H
CPUID
此时的EDX:ECX就是序列号的第64位。
回复人：westaf(2000-7-28 21:22:00) 得80分
不敢当。
要想关闭这个ID，可执行下列代码：
MOV ECX,119H
RDMSR
OR EAX,00200000H
WRMSR
不过，一旦执行上述代码，cpu将一直不能取id，直到下次reset。
