The appropriate system management driver must be loaded in order to properly differentiate an NMI caused by the jumper pins or dump switch from a PCI SERR NMI. The jumper pins and dump switch operate even if the appropriate driver is not loaded. If present, the driver disables the Automatic Server Recovery (ASR) feature so that the server does not reboot when a debug session is in progress. The NMI Crash Dump jumper pins or switch may not work in all situations: after another NMI has already occurred in the system, when the OS crash handler is incapable of running properly, and following some hardware failures.
