PCI Hot Plug Operating System Support

PCI Hot Plug slot. Activating or deactivating a PCI Hot Plug slot can also be
accomplished through the operating system PCI Hot Plug software application.

Plug Operating System Support" in the following section, and the PCI Hot
Plug Important Facts in the online PCI Hot Plug Administration Guide on the

Software support is an integral part of PCI Hot Plug. Compaq, in partnership
with Microsoft, Novell, and SCO, has developed PCI Hot Plug software
support for each operating system.
You can use either the PCI Hot Plug Button on the server or your operating
system PCI Hot Plug software to control the PCI Hot Plug slots. You can use
the software to indicate that you want to replace a card in the hot-plug slot or
configure a board that you have already added to the system. The PCI Hot
Plug software also allows you to enable or disable specific slots in the system.
NOTE: IBM OS/2, Sun Solaris, and Banyan Vines do not support PCI Hot Plug.
