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： Plural information handling systems interface through a KVM switch with a DVI display with the KVM switch supporting selection of the information handling system providing display information to the display. A hotswap switch initiates a hotswap signal to the information handling system that is selected to provide display information to the display. Receipt of the hotswap signal at the information handling system results in the driver of the selected information handling system redetecting the display with a communication through the DDC channel and transfer of EDID information from the display to the selected information handling system so that the selected information handling system drives a desired display port, such as by sending display information through a TDMS channel instead of default VGA channel.
