Other potential problem areas and checks:
* Can you use tftp to read your BDI-new.cfg file from the tftp server
(i.e. tftp localhost)?  If so, you have your server basically
functioning.  Good.

* Can you use tftp to read it from _another_ machine?  If not, you have
a permissions problem likely relating to firewalling (TFTP not allowed
to the ethernet).

* Depending on your tftp server setup, you may need
/tftpboot/BDI-new.cfg or /BDI-new.cfg (the later configuration is
strongly recommended).
