  • Patent number: 11789820
    Abstract: A system and method for preventing a hang up after initiation of a watch dog time out in a computer system. A start-up routine is run via a basic input output system (BIOS). The routine applies settings for hardware components. It is determined if a watch dog timer triggered a restart from timing out when the start-up routine ran previously. The system checks a database storing settings for each of the plurality of hardware components for a proper setting for the hardware components if the watch dog timer triggered the restart. The system applies the settings from the database for the hardware components to avoid another hang up.
