Dell Hot Plug PCI, A00-00

The PCI Hot Plug (PHP) Filter Driver layers filter devices (FIDOs) into PCI adapter devnodes to provide PCI Hot Plug functionality in Windows 2000. The creation of these devnodes is initiated by the Windows 2000 PCI bus driver (pci.sys) during enumeration of the PCI bus. Because the PHP ASIC is a PCI device, the PCI Hot Plug Filter Driver also acts as a WDM driver, controlling the PHP ASIC. The PCI Hot Plug Filer Driver takes advantage of Windows 2000's Plug and Play support to implement hot addition, removal and replace (replace is actually a remove followed by an add) operations. The PCI Hot Plug Filter Driver is dependent on the Windows 2000 architecture and will not function on previous Windows NT versions.
