Abstract
Embodiments of information handling systems and methods are provided herein to selectively control ownership of a hardware watchdog timer (WDT) provided on a system platform of an information handling system (IHS), which is configured to store and execute boot firmware, an operating system (OS) and one or more user applications. One embodiment of a method disclosed herein may include receiving user input in a boot setup utility of the boot firmware to select between OS-ownership and user application-ownership of the hardware WDT during OS runtime, and controlling ownership of the hardware WDT during OS runtime based on the user input received in the boot setup utility. Another embodiment of a method disclosed herein may authorize one or more user applications prior to controlling ownership of the hardware WDT during OS runtime, so that only authorized user applications are enabled to use the hardware WDT.
