I bought it used.  Didn't get a manual.  It may be online, but odds are
it wouldn't say jack about how to configure a TFTP server.

That's because my question was "how do you configure a TFTP server", not
something about this router or DHCP.  It's an Actiontec MI424-WR rev D,

http://dd-wrt.com/wiki/index.php/MI424WR is "Prep a TFTP server or
install one for use.".  Installation and (re)starting one I got.

The JTAG port was removed in rev D.  If I brick it, looks like I'm hosed.
