Preboot Services Setup

This section provides information on how to check the configuration of ZfD 3.2 Preboot Services after it has been installed.

Before you can configure Preboot Services, you need to use the Preboot Services CD (or the downloaded CD image) to install the PXE components on either a Windows NT/2000 or a NetWare server. For detailed ZfD 3.2 Preboot Services installation and setup instructions, see Administration in the ZENworks for Desktops 3.2 Preboot Services documentation Web site at http://www.novell.com/documentation.

Checking the Setup on a Windows NT Server

If the NT/2000 server where the Preboot Services components were installed is also a DHCP server, refer to the instructions for configuring the DHCP service to work correctly with the PXE Proxy DHCP service in Administration at the ZENworks for Desktops 3.2 Preboot Services documentation Web site at http:\\www.novell.com\documentation.

When the ZfD 3.2 Preboot Services components are installed, the following services should be installed and running on the server:

• Proxy DHCP Server
• MTFTP Server
• TFTP Server
• Transaction Server

You should not need to change the default configuration of these services unless the default multicast IP is already in use in your environment or you moved any of the PXE-installed files from their default directories.

Checking the Setup on a NetWare Server

If the NetWare server where the Preboot Services components were installed is also a DHCP server, refer to the instructions on configuring the DHCP service to work correctly with the Preboot Services Proxy DHCP service in Administration at the ZENworks for Desktops 3.2 Preboot Services documentation Web site at http:\\www.novell.com\documentation.

When the ZfD 3.2 Preboot Services components are installed, the following services should be installed and running on the server:

• PMAP.NLM
• TFTP.NLM
• PDHCP.NLM
• DTS.NLM

You can use the PXESTART.NCF file to start Preboot Services with a single command.

You can use the PXESTOP.NCF file to stop PXE services with a single command.

You should not need to change the default configuration of these services unless the default multicast IP is already in use in your environment or you moved any of the PXE-installed files from their default directories.

Configuring a PXE-Enabled Workstation for Preboot Services

To image a workstation by using ZfD 3.2 Preboot Services, you need to find out if the workstation is PXE capable, and then make sure that PXE is enabled. (When PXE is enabled, it can lengthen the time of the boot process slightly, so most NICs have PXE turned off by default.)

To enable PXE, open the workstation BIOS and analyze the boot up options. The PXE activation method for a workstation varies from one manufacturer to another, but generally one of the following methods is used:

• Some BIOSs have a separate entry in the BIOS configuration to enable or disable the PXE functionality. In this case, set either the PXE Boot setting or the Network Boot setting to Enabled.
• Some BIOSs extend the entry that allows you to configure boot order. For example, you can specify that the system should try to boot from a diskette before trying to boot from the hard drive. In this case, set the system to try Network Boot before trying to boot from a diskette or from the hard disk.
• Workstations that do not have the network adapter and PXE integrated into the motherboard will use the installed NIC management software to prompt you to start PXE configuration during the boot process. For example, many network adapters that are PXE aware will prompt you to press Control+S during the boot process to allow you to configure the PXE functionality. Other network adapters may prompt you to press Control+Alt+B or another key combination to configure PXE.
• If PXE is not listed and if the NIC is embedded in the motherboard, refer to the integrated devices section of the BIOS, which may have have an option to activate PXE. PXE may be called by another name, such as MBA (Managed Boot Agent) or Pre-Boot Service.

After you have activated PXE, it will become available in the Boot section of the BIOS. PXE is correctly enabled on a workstation when the workstation attempts to establish a PXE session during the boot process. You can see this happening when the workstation pauses during the boot process and displays the following on the screen:

The actual message displayed will vary from one manufacturer to another, but you will be able to identify it by the obvious pause in the boot process as the workstation searches for DHCP.

Configuring a Non-PXE-Enabled Workstation for Preboot Services

Some older workstations might not support PXE and will require you to install PXE on them. There are several ways to do this:

• Update your NIC or NIC driver. Most network adapter manufacturers will supply a PXE Boot ROM chip that you can fit into your network adapter to enable PXE on the workstation. Contact the NIC manufacture or a supplier to see if they sell a PXE Boot ROM. It is also possible that your current NIC may need an upgraded driver to become PXE-enabled.
• Update your BIOS version. Most manufacturers that supply motherboards with the network adapter embedded in the motherboard will offer a BIOS upgrade that will PXE-enable the workstation. Check the manufacturer's Web site or contact a supplier to check for a BIOS upgrade.
• Use the ZfD 3.2 Preboot Services PXE-On-Disk utility if no PXE is available for your workstation. With this utility, you can create a boot diskette that enables the workstation to participate in the PXE environment.

  You can access the PXE-On-Disk utility with the Create PXE Disk button in Imaging Boot Disk Creator. (To start this utility from ConsoleOne^TM, click Tools > ZENworks Utilities > Imaging > Create or Modify Boot Diskette.)

  For more information about using PXE-on-Disk and for a list of supported network adapters see the PXE-on-Disk User Guide. To access this guide on a Windows machine that has PXE components installed on it, at the desktop click Start > Programs > ZEN Preboot Services > PXE on Disk > PXE on Disk Manual.

  You can also access the PXE-on-Disk User Guide at the ZENworks for Desktops 3.2 Preboot Services documentation Web site at http://www.novell.com/documentation.

Setting up Standard DHCP and Proxy DHCP Services on a Windows 2000 Advanced Server

Use the following steps to set up Standard DCHP and Proxy DHCP Services on the same Windows 2000 Advanced Server:

1. At the command prompt, enter netsh.

2. At the netsch prompt, enter dhcp server.

3. At the dhcp server prompt, enter the following:

   add optiondef 60 ClassID STRING 0 PXEClient

4. Add the definition type in the DHCP setup menus.
