Yes, I guess it was pulled in working order from a serverroom. It boots 
IRIX as long as i don't put netBSD over it. I can't do anything with the 
IRIX-install as i don't have the rootpass... But anyway, I guess it's 
correctly terminated and such...

I also read this on this mailinglist:

http://mail-index.netbsd.org/port-sgimips/2001/11/14/0004.html

..seems there's no solution since? Maybe any one a clue for a working 
(older) kernel for the Challenge S? I don't mind the mezz-board and my 
phobos G100 card won't work(for now) ;-)
