Hot-Plug PCI allows users to install and remove PCI devices while the computer is running. Microsoft Windows 2000 and the next release of the Windows operating system, code-named Windows "Whistler," support Hot-Plug PCI through ACPI. To take advantage of Hot-Plug PCI support on Windows operating systems, manufacturers of hot-pluggable PCI devices and Hot-Plug PCI controllers should develop standard Plug and Play drivers for their devices, and implement insertion and removal notifications as defined in ACPI 1.0b. Hot-Plug PCI controllers should also implement the _HPP object as defined in ACPI 2.0 for Windows Whistler, and follow standard rules for implementing ACPI events when connecting to General Purpose Events (GPEs), as described in this article.
