    摘要: In accordance with the present disclosure, a system and method for a managed BIOS is disclosed. A software for a BIOS in an information handling system is provided on a computer readable medium. A first code, for execution on a central processing unit (CPU), is operable to initiate a connection to a management controller through a controller, send a message to the management controller through the controller, and receive a message from the management controller through the controller in response to a system management interrupt. The first code is also operable to stall a power-on procedure if it is able to determine a plurality of bootable devices before the connection to the management controller is ready. The first code is further operable to stall the power-on procedure before releasing control to an operating system if the management controller is active.

    摘要: A method of using a counter stored in flash memory includes providing a base value field, a selector field, and a plurality of increment fields. The base value field represents a base value for the counter, and the selector field indicates a first one of the increment fields. The method further includes changing a bit of the first increment field from an erased value to a written value to indicate a change in a value stored in the counter.

    摘要: Audible noise related to power state transitions of an information handling system processing component, such as the central processing unit, is reduced by randomizing the time between power state transitions. Random power state transitions are managed by an operating system module that tracks the transitions and selects random times for subsequent transitions within a predetermined time range. Alternatively, an arbitrating circuit intercepts power state transition commands and arbitrates their communication at random times. Random power state transitions reduces audible noise by spreading the frequency of the noise-causing power transition events over a wider band.

    摘要: A switched power rail monitor compares voltages provided by a switched power rail and a power source to detect a predetermined differential indicative of a fault at the switched power rail. A switched power rail fault is communicated to a power manager to take corrective action, such as cutting off power to information handling system components. In one embodiment, a pair of bipolar junction transistors monitor the voltage differential to send an enable signal if the differential is within limits and a disable signal if the differential exceeds limits.
