4.1.9 Watchdog Timer for Booting
The BIOS of Nuvo-5095GC series has a useful feature which allows users to use the
watchdog timer to secure the booting process. You can specify the timeout value for
watchdog timer. Once the watchdog timer expires, the BIOS issues a reset command to
initiate another booting process. You can also set the behavior of how to stop the watchdog
timer. 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 to OS, otherwise another booting process will
be initiated. For information about programming watchdog timer, please refer to
Appendix
