Sun Ultra systems must have PROM version 3.25.xx or later to use the Dynamic Host Configuration Protocol (DHCP) network boot.
On Sun Ultra systems, you can install an updated version of the PROM's firmware to keep your PROM (and your version of OpenBoot) up-to-date. Updating your PROM is not covered on the exam, but if you would like more information on performing this procedure, refer to publications listed at the end of this chapter.
