Phase 1: Beginning the Process
Depending on whether novell-proxydhcp is configured on the same server as the standard DHCP
server or on a different server, the imaging process begins differently. The following sections
illustrate how the process begins for each configuration, then the phases illustrated in
through 8: Continuing the Process" on page 342

Standard DHCP and Novell Proxy DHCP Configured on Separate Servers
For this example, the DHCP server and the Preboot Services imaging server are two separate servers
on the network.

Processes:
1. When the device boots, the PXE BIOS issues a DHCP request with PXE extensions. The
request is broadcast on port 67.
2. The DHCP server responds with IP configuration information on port 68, and the Proxy DHCP
server responds on port 68 with the name of the bootstrap program (
address of the TFTP daemon where it can be found.
3. Continue with
Standard DHCP and Novell Proxy DHCP Configured on the Same Server: Part A
For this example, the DHCP server and the Preboot Services imaging server are configured on the
same server on the network. See
