How well does setting the serial console help in this case? I've not used it, as my remote admin experience is with hardware that lets you talk to the mobo rom via a serial line. If the appropriate serial flags will let you work in single user mode over a serial line, then you can do the installworld in single user mode. If they let you boot an alternate kernel over a serial line, then you're set, aren't you? http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
