Abstract: A halt event separates a boot up operation from a run time operation. A controller grants a request from a baseboard management controller for an electrical power associated with a boot-up operation. As the baseboard management controller completes the boot-up operation (such as a power on self-test), the baseboard management controller predicts the electrical power that is required for a run time operation (e.g., executing an operating system). The baseboard management controller is then required or forced to submit a subsequent request for the additional electrical power that is required for the run time operation. The controller compares the electrical power predicted for the run time operation to a power availability from a power supply (such as a safe or maximum operating condition). If the power supply can provide the electrical power predicted to be required during the run time operation, then the controller may permit or authorize a transition from the boot up operation to the run time operation.
