Abstract: A power supply architecture combines the benefits of a traditional single stage power delivery, when there are no additional power losses in the integrated VR with low VID and low CPU losses of FIVR (fully integrated voltage regulator) and D-LVR (digital linear voltage regulator). The D-LVR is not in series with the main power flow, but in parallel. By placing the digital-LVR in parallel to a primary VR (e.g., motherboard VR), the CPU VID is lowered and the processor core power consumption is lowered. The power supply architecture reduces the guard band for input power supply level, thereby reducing the overall power consumption because the motherboard VR specifications can be relaxed, saving cost and power. The power supply architecture drastically increases the CPU performance at a small extra cost for the silicon and low complexity of tuning.

Some embodiments may detect events associated with high power demand and may preemptively configure the power circuit of the IHS for providing high-power outputs upon detecting such events.

Abstract: A BIOS image can be selectively updated. An image loader of the BIOS can be configured to detect whether a BIOS image to be loaded includes a selective update capability field, and if so, employ a value defined in the selective update capability field to determine whether an updated BIOS image exists. When an updated BIOS image exists, the image loader can load the updated BIOS image rather than the BIOS image. In this way, an individual BIOS image can be selectively updated without needing to update the entire BIOS.
