4.1.10 Watchdog Timer for Booting
The BIOS of Nuvo-6000 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 B
