4.1.10 Watchdog Timer for Booting
The Watchdog timer setting in the BIOS ensures a successful system boot by
specifying a timeout value. If the Watchdog timer is not stopped and expires, the
BIOS will issues a reset command to initiate another boot 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 stop the watchdog timer after POST (Power-On Self Test) OK. When
“
Manually after Entering OS
” is selected, it’s user’s liability to stop the watchdog
timer when entering OS. This guarantees the system can always boot into OS,
otherwise another booting process will be initiated.
