\ Diagnostic loading feature.  Directly loads a named file using TFTP,
\ instead of first loading the boot file that the server provides.
\ Also reads the symbol table if it is present.
\ The server must be configured for "non-secure" tftp; i.e. the tftp
\ daemon must be started without the "-s" flag.  See /etc/inetd.conf
