4.1.12 Watchdog Timer for Booting
The watchdog timer secures the boot process by means of a timer. Once the timer expires, a
reset command is issued to initiate another booting process. There are two options in BIOS
menu, “ Automatically after POST ” and “ Manually after Entering OS ”. When “ Automatically after
POST ” is selected, the BIOS automatically stops the watchdog timer after POST (Power-On
Self Test) OK. When “ Manually after Entering OS ” is selected, the user must stop the watchdog
timer once booted into the OS. This guarantees the system can always boot into the OS,
otherwise another booting process will be initiated. For information about programming
watchdog timer, please refer to Watchdog Timer & Isolated DIO .

1.
