|Input||- none -|
|Output||- none -|
|Description|| This system service routine switches
off NMIs to the processor.
NOTE: As the NMI interrupt is used to provide the system clock the system time will be invalid. It is possible to switch off NMIs and still maintain a valid system time (see BT$NOF).
If NMIs are switched off with this service then they should be switched back on with the BT$NMEN service.
