摘要： Bus numbering management for an information handling system, such as a personal computer, is provided by interfacing one or more selectively hidden devices with one or more buses through either a hardware or software implementation. If an inactive bus becomes active, then disabling of a selectively hidden device interfaced with another active bus provides a bus number to the newly active bus. For instance, if a graphics capability is added to a computer system through a PCI bus, a PCI bridge associated with a second PCI bus is disabled so that the PCI bus number for the portion of the second PCI bus between the chipset of the computer system and the PCI bridge is available for use as the PCI bus number for the PCI bus associated with the graphics capability. The PCI bus number for the portion of the second PCI bus between the PCI bridge and existing peripheral devices is available for use for both portions of the second PCI bus. Thus, peripheral devices associated with the second PCI bus will continue to be recognized by the operating system as associated with the same PCI bus number. Alternatively, instructions associated with the PCI bus controller enables or disables a virtual device by handling input/output accesses.

摘要： An information handling system (“IHS”) includes a processor and a memory device for storing instructions processable by the processor for causing the IHS to determine whether configuration of a basic input output system (“BIOS”) has been modified. The instructions are also processable by the processor for causing the IHS to, in response to determining that the configuration has been modified, determine whether a previously stored configuration is likely a valid configuration. Moreover, the instructions are processable by the processor for causing the IHS to, in response to determining that the previously stored configuration is likely a valid configuration, store the configuration that has been modified in a new location of a storage device. Furthermore, the instructions are processable by the processor for causing the IHS to, in response to determining that the previously stored configuration is likely not a valid configuration, store the configuration that has been modified in a location of the storage device that stores the previously stored configuration.
