thinkpad DVD/CD-ROM HL-DT-ST GSA-T50N 升级SP3后丢失驱动问题

前几天XP升级了SP3,导至thinkpad的光盘不可用，光驱型号HL-DT-ST GSA-T50N。找了很多资料都不行，就是微软自己的这个检测工具都不行:
http://diagnostics.support.microsoft.com/diagprov/provision/MicrosoftFixit.dvd.RNP.160282074827208017.3.1.Run.exe?_tenant=mats&diagid=dvd&entrypointid=RNP&logsessionid=160282074827208017&eventseqno=3&buttonclickno=1&_ext=.exe

最后在http://forums.driverguide.com上找到了解决方法:

step1: 卸载自己的光驱驱动,
step2: 解压以下附件文件,导入那二个文件到注册表
step3:重新扫描驱动，搞定。




XP的SP3补丁包升级后好像会导致一些设置出现莫名其妙的问题，比如我的就出现过：
键盘无反映、声卡莫名丢失驱动，光盘无法使用等等问题
