正在获取CPU或主板序列号?

您需要使用CPUID指令。

CPUID

大多数C编译器都支持内联程序集,但您需要知道自己在做什么。

在Linux下,可以使用“lshw-quiet-xml”并解析其输出。您可以在这里找到大量的系统信息:cpuid、主板id等等。

你可以得到CPUID。 也许linux命令“dmidecode”可以帮助您。 可以执行此命令,也可以加载“dmidecode”的源代码。 接下来是“dmidecode-t处理器”的输出:

>dmidecode -t processor
# dmidecode 2.7
SMBIOS 2.2 present.

Handle 0x0004, DMI type 4, 32 bytes.

        Version: Intel(R) Pentium(R) 4 CPU
        Voltage: 1.5 V
        External Clock: 133 MHz
        Max Speed: 3066 MHz
        Current Speed: 2800 MHz
        Status: Populated, Enabled
        Upgrade: ZIF Socket
        L1 Cache Handle: 0x0008
        L2 Cache Handle: 0x0009
        L3 Cache Handle: No L3 Cache

在Linux中,主板信息可以在/sys/class/dmi eg下找到

$ sudo grep '' /sys/class/dmi/id/board_*
/sys/class/dmi/id/board_asset_tag:
/sys/class/dmi/id/board_name:30AD
/sys/class/dmi/id/board_serial:
/sys/class/dmi/id/board_vendor:Hewlett-Packard
/sys/class/dmi/id/board_version:KBC Version 56.34

…但并不是所有的主板都能通过dmi提供序列号…如图所示。

CPU不再获取序列号,现在已经有一段时间了。对于CPUID-它是每个CPU模型唯一的,因此它对许可没有帮助。
