# PCI Hot Plug Support

The Intel PRO/1000 network adapters are enabled for use in selected servers equipped with PCI Hot Plug support, running

- Windows NT* 4.0

- Windows* 2000, XP Professional (32-bit)

- NetWare* 4.11 and Above

- UnixWare* 7 with ddi8 and Open UNIX* 8

- Sunsoft* Solaris* 7 and Solaris 8

- Linux

| NOTE: PCI Hot Plug is not supported in Microsoft Windows 98 and Millennium.
| NOTE: If you replace an adapter in a PCI hot plug slot, don't 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.

## Windows NT 4.0

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.

## Windows 2000, XP

Check with your hardware and/or Hot Plug support documentation for details.

## NetWare 4.11 through 6

Make sure you have the latest NetWare support pack installed before using PCI hot plug (see System Requirements to download the support pack). If your server uses any teaming features (with iANS), the driver will be loaded persistently. If teaming options are not used, the driver will unload when the slot power is off and reload when the slot is powered again. The keyword, PERSIST, can be used to control this behavior, as follows:

0 = Never persist
1 = Always persist
2 = Auto persist (default). Base driver remains loaded only if iANS loaded.

| NOTE: If you are not using teaming (iANS) or VLANs, use parameter 1 – always persist.

## UnixWare 7 with ddi8 and Open UNIX 8

Software Requirements:

UnixWare 7 DDI8 driver.

UnixWare 7.1.0 or later with appropriate PCI hot plug controller driver and UnixWare 7.1.x hot plug patches installed.

Open UNIX 8 driver.

For installation and configuration see the UnixWare 7 and Open UNIX 8 driver instructions.

Hardware Requirements:

PCI hot plug capable server with latest BIOS installed to support PCI hot plug.

## Sunsoft Solaris 7 and Solaris 8

Software Requirements:

Solaris 7 11/99 or later operating system.

Hardware Requirements:

Four processor AC450NX class machines support PCI hot plug in Solaris x-86 operating systems.

For additional Solaris hot plug details, see the Driver Installation Notes.

## Linux

PCI Hot Plug is supported by the Intel network driver for Linux. However, PCI Hot Plug also requires that the system hardware and operating system support PCI Hot Plug.
