You have to mount the Linux device filesystem (so it can "see" the control nodes) but it is fully functional and gives you command-line interactivity to the board. You can absolutely configure and interact with it from FreeBSD. The program is annoying as heck as by default it writes a logfile on EVERY INVOCATION, but it does the job and allows you to configure and maintain the board, which is kinda important as if it detects an error (e.g. failed unit) it will start beeping - the board has an audible alarm on it. I have one of these boards - its quite nice and VERY fast - if someone wants it I would be willing to sell it (I've got the battery-backed RAM option on it too, which makes it MUCH faster; that's a usually-rather-expensive option) -- -- Karl Denninger karl@denninger.net --------------070604020003070909020801--
