用击键序列强制内存转储，究竟是修改目标计算机还是主机的注册表？

各位大侠：
用击键序列强制内存转储：windows2000允许用户生成一个击键序列，Ctrl-Scroll Lock (同时按压键盘上的两个键)；修改计算机的注册表：
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters：
值名字：crashonctrlscroll；
数据类型：REG_DWORD;
值：1；
向诸位请教：究竟是修改目标计算机还是主机的注册表？
jerry在附录A.3讲的，但没明确是在哪里。
 

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).

This feature is disabled by default. To enable this feature, you must edit the registry as indicated below and restart the computer. After restarting the computer, you can generate a system to stop responding by holding down the right CTRL key and pressing the SCROLL LOCK key twice. Pressing left CTRL key does not generate the system to stop responding.

Please note that the steps below will not work on Legacy Free computers, i.e., those that use a USB keyboard. For those, you must attach a debugger.

Start Registry Editor (Regedt32.exe).


Locate the following key in the registry:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters
On the Edit menu, click Add Value, and then add the following registry value:


Value Name: CrashOnCtrlScroll
Data Type: REG_DWORD
Value: 1
Quit Registry Editor.
