If you are using bootpd, you must have in
/etc/bootptab the lines:
<client_host_name>:hd=/tftpboot:\
                  :bf=/tftpboot/vmlinusz:[\...]

But if you are using the dhcpd - which also offers
bootpd services, than you must have in etc/dhcpd.conf
a subnet section like:
subnet <yor.net.add.0> netmask 255.255.255.0 {
    host <cl_host_name> {
        hardware ethernet hh:hh:hh:hh:hh:hh;
        fixed-address <yor.cl.ip.add>;
        filename "/tftpboot/vmlinusz"
    }
}

The last one is what I am using and it works!

Hope it will help you,
