Hello,

I saw the code in CE source. I was intrested in the kernel mode debugging file, how can I use this? Just call the Start one + the SetBreakpoint? Is that all or do I've to do a lot of things in usermode to?

Hope anyone can help me,

Not that easy at all.
First you need an interface with the driver so you can give it commands
Then you need to hook the specific cpu's interrupt handler (setting the correct cpu is done in usermode)
Then when the debugging has started you must handle all the debugging mechanisms yourself in usermode. (Setting the trap flag, resume flag, telling it to continue handled or unhandled, etc..)

Look at kerneldebuggerinterface.pas and dbk32functions.pas
