Abstract: A methodology by which a host computer can dynamically rebalance PCI-to-PCI bridges to overcome Operating System/BIOS and Chipset limitations in order to allow multiple level PCI buses. This methodology also allows hot-swappable PCI buses to be added and removed without failure. Additionally this method allows for proper I/O resource allocation where previously alliasing preventing this. The present invention overcomes the limitations of an Operating System, such as Windows 2000 and Windows XP, to allow a PCI bus segment to be added by rebalancing the PCI bus tree and resource requirements as needed in order to fit the new PCI bus segment.

Abstract: A dual input battery assisted power converter (10) which provides a continuous, regulated DC voltage output to a user-connected mobile device, such as, a lap top computer or a cell phone, for example. The power converter (10) comprises a power supply circuit (12) and a separate, detachable power storage circuit comprising a battery pack (14) having a re-chargeable battery (36). The power supply (12) is adapted to deliver a pair of regulated DC output voltages, of opposite voltage potentials, to a pair of respective output terminals. Preferably these output voltages are derived from two external input voltages: an AC input voltage and a DC input voltage. Advantageously, if both of the external input voltages are temporarily removed, the battery pack (14) will advantageously serve as a substitute DC input power source, thereby allowing the power supply (12) to deliver the same regulated DC output voltage to the user-connected mobile device without interruption.
