Abstract: A method for registering and initiating a pre-boot environment for enabling partitions. The method provides a basic input output system (CIOS) with an application program interface (API) that accesses a Logical Clock Address (LCA) sector number when a boot configuration flag is set, the LCA sector number stores an operating environment manager which then boots the information handling system to an appropriate partition.

Abstract: A method of preventing windup in a PID controller when using a nonlinear gain parameter is disclosed that is used in the PID controller of a process control system. The PID controller is arranged to produce within a current execution cycle a Control Variable (CV) to a device that is controlling a process responsive to an input Process Variable (PV), a setpoint (SP), and a gain parameter (K). The present invention receives the PV, the SP, and the K and generates a proportional, integral, and derivative component of the deviation of the PV from the SP. The components so generated are used to calculate an incremental output CV for the current execution cycle. A current value of gain is next calculated by subtracting the value of the gain for the current cycle from the value of the gain from the previous cycle. Testing for a linear or nonlinear gain parameter is done next and, responsive to a nonlinear gain parameter, a nonlinear gain change component is calculated and added to the incremental output CV.
