[K12OSN] Passing Parameter to kernel :- option option-129 "DPORT=1067";

[Jim McQuillan]

Pap,

You also need to include option-128.  It should look like this:


   option option-128   e4:45:74:68:00:00;
   option option-129   "DPORT=1067";


The value for option-128 is a special 'Etherboot signature', NOT
a mac address.

If you put the lines in your dhcpd.conf file exactly as I've shown
above, it should then pass the DPORT parameter on to the kernel and
initrd.
