     1= DHCP Service =

     3The Dynamic Host Configuration Protocol (DHCP) provides a way to automate and manage the network configurations of all ORBIT attached devices. It has two main functions:
     4
     5  1.) Assigning networking (IP) configuration
     6  2.) Support for PXE booting

     36=== PXE Support ===
     37
     38The PXE protocol uses a very complex set of extensions to DHCP and/or BOOTP but most of the newer implementations seem to be able to boot with standard DHCP configuration. 
     39
     40A DHCP configuration for PXE support is:
     41
     42{{{
     43        allow booting;
     44        allow bootp;
     45
     46        # Standard DHCP configuration directives...
     47
     48        # Needed for PXE
     49        filename "/pxelinux.bin";
     50        option option-150 code 150 = text;
