hardware hardware-type hardware-address;

In order for a BOOTP client to be recognized, its network hardware address must be declared using a hardware clause in the host statement. hardware-type must be the name of a physical hardware interface type. Currently, only the ethernet and token-ring types are recognized, although support for a fddi hardware type (and others) would also be desirable. The hardware-address should be a set of hexadecimal octets (numbers from 0 through ff) separated by colons. The hardware statement may also be used for DHCP clients.
