PCI Hot Plug

Windows NT

Windows NT requires additional software from the vendor who makes the system. Since this software is not a part of NT, the software needs to be installed after the operating system is loaded. Refer to your system or server vendor's PCI Hot Plug documentation.

￿Caution

GAM drivers can stop PCI Hot Plug Boards from unloading. If this problem occurs, stop GAM and unload the GAM drivers before attempting to unload the PCI Hot Plug controller.

Known Windows NT Issues

•Mylex Software Kit 2.1 or greater is required to support your system vendor’s PCI Hot Plug utility.

•The macdisk.sys driver should not be loaded with a Mylex PCI Hot Plug board; if macdisk.sys is loaded, the system will hang upon shutdown.

•When you install a Mylex controller as a boot device and a Mylex Driver has been installed prior to the installation of the Windows NT OS, NT will not recognize the Mylex controller as a PCI Hot Plug device. To fix this, the driver must be reinstalled, and the system rebooted.

This problem occurs because PCI Hot Plug information does not get loaded into the Windows NT registry for the Mylex controller upon installation of Windows NT.

Windows 2000

Windows 2000 supports the PCI Hot Plug capability. No additional software is required.

Please refer to the Windows 2000 documentation for instructions on how to use the PCI Hot Plug feature.
