Even without a watchdog this could be useful since if a system fails to
boot off the primary kernel the system locks up. The user would press
start again or the reset button since the system had failed to start.
This second time up LinuxBIOS would be aware of the last failed boot
attempt and try a secondary kernel location or wait for user interaction
via key combinations to redirect to jump to load a good kernel.
