If you try to debug by using a 1394 PC Card, debugging may not be turned on in some cases.
This problem occurs because the hardware abstraction layer (HAL) may not wait long enough for the CardBus bus to be initialized. Or, in other cases, the HAL may not wait long enough for the card to be initialized after power is applied. When this occurs, Windows does not actually start in Debug mode even if you use the correct Boot.ini file switches and Kd1394.dll is loaded.

You can verify whether Debug mode is in use by building a program that contains the following sample code:
void main(void)  {     _asm {  int 3 }     return 0;}				
If Debug mode is in use, the program hangs (it breaks into the debugger) when you run this code. If Debug mode is not in use, you receive a Dr. Watson error message.
