Sorry.  I should have been more clear.  What I meant to ask was, do you
have an overview for the syntax used by the DS5K/200 boot PROMs to
communicate with the tftp server?

I could always attach the HDD to the baseboard controller, install,
upgrade to -current then attach to the TCDS and boot, right?
