netboot doesn't work for hp c360

I am going to use as a server my FreeBSD machine and
use bootp to do the insallation. I have a tutorial
about DHCP servers and also the OpenBSD hppa
installation guide, but their application has been
unsucessful.
As far as i understand the isc-dhcp package can be
used to setup a DHCP sever and can also serve bootp. I
followed the OpenBSD guide instructions and created
the /etc/dhcpd.conf, which contains the following:
-----------------------------------------------------
subnet 10.0.0.0 netmask 255.0.0.0 {
host boron {
filename "lif36.fs";
hardware ethernet 00:10:83:03:3F:55;
fixed-adress 10.42.42.42;
}
}
----------------------------------------------------
I enabled dhcp, did "sea" (search for boot devices) in
the c360, but without success.
In the tutorial i edited /usr/local/etc/dhcp.conf, the
generic configuration file with only the above (the
same i had put in /etc/dhcpd.conf), but also without
success. "boot lan isl" doesn't work either. Any
ideas?
Thanks
