//set time counter register: 0xac, 0xab, 0xaa
outb

outb (( wdog_time >> 8 ) & 0xFF , 0xab ); //D15...D8
outb ( wdog_time & 0xFF , 0xaa ); //D7...D0
//set trigger: 0xa9
trig
= inb ( 0xa9 );
trig &= 0x0F ;
trig |= 0xD0 ; //0xD0 = system reset

//enable wdog: 0xa8

Please note that this source code example is provided for a system running Linux. For
other operating systems, it may be necessary to adapt the source code regarding include
files or headers and the syntax of I/O out commands because Linux is using outb(value,
address) instead of outb(address, value).
