Introduction
Define Pin Address
#define WDT_ENABLE 0x600 #define WDT_DISABLE 0x604 #define DO 0x60C #define DI 0x608
Set the I/O privilege level
iopl( 3 ); //iopl() changes the I/O privilege level of the current process , level 3 can read/write to i/o port
Set DO
DO:
outb( 1 , DO ); //write data:1 to DO
Read DI/DO
DO: inb ( DO ); //read DO data DI: inb ( DI ); //read DI data
Enable/Disable WDT
Enable : outb ( 1 , WDT_ENABLE ); //set 1 sec to WDT enable port, system will reboot after 1 second Disable: outb ( 1 , WDT_DISABLE ); //set 1 sec to WDT disable port , the disable signal will break off WDT enable signle
