4.1.5 Watchdog Timer for Booting
The BIOS of Nuvo-3000 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 responsibility 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 A Using
Watchdog Timer & Isolated DIO
.

1. When Nuvo-3000 boots up, press F2 to enter BIOS setup utility.
2. Go to
[Boot]
menu.
3. Disable or select timeout value for
[WDT for Booting]
option.
4. Once you give a timeout value, the
[WDT Stop Option]
option appears. You can select
“Automatically after POST”
or
“Manually after Entering OS”
.
