The file may contain code and symbols, but using "-s=..." will cause gdb
to ONLY read symbols. This is why gdbtk was failing to disassemble
anything.

It would make sense that you could not disassemble (and maybe even not
see source). Like I said before, if you are not attached to a remote
target, gdb (and gdbtk) will look at the code you've loaded to do
disassembly. Since you didn't load any code, gdb couldn't show you
anything.

Cool! Not bad for my first guess. :-)

No, you should be able to invoke gdb/Insight passing the file on the
command line:
$ gdb [args, sans the -s one] myExecutable.cof

In general, the use of "add-symbol-file" and the "-s" command line flag
should be used to read ADDITIONAL symbols into gdb. (Purists will say
that this is not true, and they are correct. However, my experience with
gdb, this advice has never failed.)
