.Sh EXAMPLES
When netbooting diskless SunOS/Xkernel SPARCstations the booted SunOS kernel
also broadcasts to the all-0 address. The SunOS kernel hangs until it
receives a reply. To accomodate this behaviour add an alias address
that responds to an all-0 broadcast. So, add something like 'ifconfig xl0
192.168.200.254 netmask 255.255.255.255 broadcast 192.168.200.0 alias'
on the relevant network interface on your bootparamd server. The alias
address must of course be free for use.
