Removal of a Board

The ENUM# signal is detected by the HSC device driver. This event is passed to the PciSwap driver, which detects which slot to remove. The parent PCI bus driver is notified for each removal. The PCI bus driver sends the device shutdown event. The PCI device closes its connection to the PCI bus. The PCI bus driver or PciSwap (or both) invokes the PCI enumerator. The dynamic (enumerated) device nodes are deleted or static nodes are deactivated. When the last connection to the PCI bus driver for the slot is closed, the PCI bus driver invokes the method of the PciSwap driver. The slot is declared FREE and can be removed.
