Abstract: An information handling system includes an embedded controller to capture a current battery power level of a battery that is a sole source of power of the information handling system. A service module may update a configuration table with anticipated power consumption associated with a component of the information handling system, wherein the anticipated power consumption is based on an operation, and predict whether the current battery power level is sufficient to complete the operation, including comparing the current battery power level with the anticipated power consumption of the component. If the current battery power level is sufficient to complete the operation, then the service module may execute the operation. If the current battery power level is insufficient to complete the operation, then the service module may provide one or more options associated with the operation based on a power management policy.

Abstract: A boot option system includes a pre-boot execution environment system coupled to a server device through a network. The server device creates a device placeholder boot option including a device path terminating at a storage controller in the server device. During a first boot and based on first boot instructions received from the pre-boot execution environment system, the server device moves the device placeholder boot option to a desired location within a boot sequence for the server device. During a second boot and based on second boot instructions received from the pre-boot execution environment system, the server device provides an operating system on the server device. The server device then replaces, at the desired location within the boot sequence, the device placeholder boot option with an operating system boot option that was provided on the server device in response to the provisioning of the operating system on the server device.

Abstract: Examples construct a bootloader address space using a page fault exception. A bootloader executing in machine address (MA) space determines the MA at which the bootloader has been loaded into memory. The bootloader calculates a difference between an expected virtual address (VA) and the loaded MA. The bootloader defines a page table mapping the bootloader MA to an expected VA, and sets an exception handling vector to point to the expected VA. When a memory management unit (MMU) utilizing the defined page table for address translation is enabled, a page fault exception occurs. The page fault exception handling resumes execution of the bootloader at the expected VA via an exception handling vector pointing thereto.
