4. After selecting the bundle for all hosts being updated, open the Select Items to be Installed screen to complete the

following tasks:

A. Select the components for installation.

B. If necessary, configure the components. The Configure Now link is not available when running

Windows Server 2012 with the Server Core option. To configure components:

i. Access the system as a remote host using HP SUM, where HP SUM is running on a system with a supported

Windows OS.

ii. Configure the components and resolve any failed dependencies before deploying the OS.

C. Review the revision history of the components.

5. After selecting the components, click Install. When the installation finishes, the Installation Results screen displays. If

the Supplement installs successfully, the process is complete. If one or more components did not install successfully,

complete the following steps:

A. Exit HP SUM.

B. Make the required update to the environment.

Configure Server Manager

To configure Server Manager, complete the processes in the following sections.

Add “IOVEnableOverride” key to the Windows Registry (on servers with an AMD processor)

If you server has an AMD processor, complete the steps in this section. If your server has an Intel processor, procede to the

2. Type the following to add the registry key:

IOVEnableOverride /t REG_DWORD /d 1

See Figure 5 for a sample of a successful addition of Windows Registry key.

3. Restart the server after you add the registry key successfully.
