— Command: dhcp [–with-configfile]

Initialize a network device via the DHCP protocol. Currently, this command is just an alias for bootp, since the two protocols are very similar. This command is only available if GRUB is compiled with netboot support. See also Network.

If you specify --with-configfile to this command, GRUB will fetch and load a configuration file specified by your DHCP server with the vendor tag `150'.
