| 摘 要： | 通过对IBM PC/XT286微机CMOS RAM的简单分析,介绍了一种方便,实用,有效的计算机硬盘保护方法。此法通过对CMOS RAM的内容进行重新设置,使硬盘在CMOS RAM中的参数发生改变,硬盘无法与系统进行通信,从而起到了保护作用。其特点是不需要对硬盘上的文件或信息进行修改,就能实现对硬盘的加锁,加锁后的硬盘不能做任何读写操作,且可以防止计算机病毒的入侵。

| Abstract: | In this paper, throrgh the analysis of the CMOS RAM in the IBM PC/XT286 microcomputer, a simpleand effecfive method for protecting compicter's harddisc has been presented. By seting the CMOS RAM'scontent and thus altering the harddisc's parameters retaining in the CMOS RAM, theharddisc will not be allowed to comnumicate with the system and thus the harddisc is protected. Itis the main feature of this method that without modfying the files or information in the harddisc,the harddisc can be locked, that is the resd and write operations will be inhibited and the contami-ation by computer's virus will also be prevented. |
