Currently only Ultra workstations can use this feature.

DHCP installation clients do not require a boot server on the local subnet because the DHCP is routable. Ensure that the system s boot PROM is at least at version to perform a DHCP boot. Performing a Configuration When you add clients using the add_install_client -d script on the installation server the script reports DHCP configuration information to standard output. Use this information when you create the symbols and macros needed to pass network installation information to clients. For example instructor . add_install_client -d -s instructor export install -c instructor export config -p instructor export install 10 sun4u To enable in the DHCP
