关于解除windows2000文件保护的问题

我在support.microsoft.com看到此文章
All registry settings for Windows File Protection/System File Checker are located in the following registry key:
HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon
SFCDisable (REG_DWORD)
0 = enabled (default)
1 = disabled, prompt at boot to re-enable
2 = disabled at next boot only, no prompt to re-enable
4 = enabled, with popups disabled

NOTE: For options 1 and 2: Both of these options require a kernel debugger to be hooked up for those options to become useable. If a kernel debugger is not hooked up, Windows File Protection is not disabled.

这里提到要使2选项有效，必须将一个kernel debugger 挂到该选项上，请问哪位高手知道具体怎么操作，我有softice，怎样挂到选项上呢？
