On my server for the diskless I have

inetd.conf:
<..>
tftp    dgram   udp     wait    root    /usr/libexec/tftpd      tftpd -s
/tftpboot
<..>


dhcpd.conf:
<..>
filename "/tftpboot/kernel";
<..>


exports:
<..>
/    -ro -alldirs -maproot=root: -network 192.168.168.0 -mask
255.255.255.0
<..>


Make sure that you also have along your lines, the previous lines!
