HighWire HW400c/2 User Reference Guide Rev 1.0 
If you don’t already have one, the easiest way to create a bootp server is to have it 
reside on the same LAN subnet as the HW400c/2. Creating bootp relay agents for 
 LAN segments is beyond the scope of this document.
 
 
o set up a server with BOOTP with TFTP ability in a standard Linux box, 
uncomment (or add) these two lines in inetd.conf) 
 
tftp    dgram   udp     wait    root    /usr/sbin/tcpd  in.tftpd 
bootps  dgram   udp     wait    root    /usr/sbin/tcpd  bootpd -d 4
 
ou may also run bootpd from the command line by entering; 
bootpd –i –d 4
 
See the man page bootpd(8) for details. To run bootpd from the command line it 
ill be necessary to disable the bootpd service if it has already been enabled and 
 /etc directory. See the man page bootptab(5), and the example below.

This section describes the processes necessary to boot using each of the three 
methods. In each case, the boot firmware U-boot, loaded in on-board flash, is 
necessary to initialize the HW400c/2. The boot instructions for three methods 
mentioned above diverge slightly from that point.
