5.1.2 Disabling the boot watchdog
The boot watchdog determines whether the operating system boots within a
preset time frame. If the watchdog timer expires, the system will automatically
reboot.
If the system is to be started from removable boot media for firmware upgrade
purposes, the boot watchdog needs to be disabled before starting maintenance
task. Otherwise, the boot watchdog might initiate a system reboot before the
flash process is complete.
V CAUTION!
An incomplete firmware upgrade process may render the server
inaccessible or result in damaged/destroyed hardware.
Timer settings can be configured in the BIOS or using the ServerView iRMC
web interface.
Disabling the boot watchdog in the BIOS
Ê Enter the BIOS.
