Certain BOOTP host software implementations will not respond to BOOTP requests if you have not included a download filename in the configuration file; if this is the case, simply create a null file on the host and specify the name of this file and its path in the configuration file.
As with rarp, the Print/Fax server will load its IP address from the BOOTP server when the machine is powered on.
