Enabling the Watchdog NMI
To activate the NMI feature, enable it in the watchdog register (Port 79h). The code to do this
might look like the following:
#define WD_NMI_EN_BIT_SET 0x10
void EnableWatchdogNmi(void){
unsigned char WdValue;
WdValue = inb(WD_CSR_IO_ADDRESS);// Read the current contents of the
WdValue |= WD_NMI_EN_BIT_SET;
outb(WD_CSR_IO_ADDRESS,WdValue); // Assert the enable in the watchdog
}
