# PCI Hot Plug Support for Windows NT* 4.0

Intel® PRO/100 and PRO/1000 network adapters are enabled for use in selected servers equipped with PCI Hot Plug support and running Windows NT 4.0.

| NOTE: If you replace an adapter in a PCI Hot Plug slot, do not place the removed adapter back into the same network until the server has rebooted. The two adapters may have the same Virtual MAC address and create a conflict.
| NOTE: PCI Hot Plug will only work when you hot-plug an identical Intel network adapter.

For more information on setting up and using PCI hot plug support in your server, see your server's documentation.

## Using Hot Plug

To use Hot Plug on Windows NT 4.0 systems, you must install the Intel DMI 2.0 Service Provider. See DMI, WMI Management Software Support for installation and configuration information.

To install an adapter using the HotAdd feature in Windows NT 4.0 on servers using IBM's Hot Plug, you must first replace the OEMSETUP.INF file in the root directory with the OEMSETUP.INF file in the Winnt\Intel directory of the Intel CD.

| NOTE: On some systems, replacing the OEMSETUP.INF file will cause a short delay when an adapter team is reset.

Use the MAKEDISK utility to create a Windows NT 4.0 driver diskette. After you have done that, replace the OEMSETUP.INF file on the floppy disk with the OEMSETUP.INF file in the Winnt\Intel directory on the Intel CD.

Use the driver diskette to install the network drivers to be used with Hot Plug.
