吐血奉献，在Windows XP/2000下直接读写访问端口，并演示了保存恢复CMOS信息的功能，演示了破解CMOS/BIOS密码的一种算法。基于DirectPort.dll。 并详细分析CMOS数据信息。 -direct I/O access,read and write cmos data,can save to a file and restore from a file in Windows XP/2000.

本程序通过在内核下访问I/O实现对CMOS读取、删除、恢复、备份的操作。-The procedure to access the kernel I/O implementation of the CMOS read, delete, restore, backup operation.

独享一个CMOS/ NV-RAM的Linux上驱动程序，原型不提了，经过本人无数次修改已经非常完美-Exclusive driver of a CMOS/NV-RAM on Linux prototype is not to mention countless revisions after I have been very perfect
