Hi Justin, sysctl hw.ncpu shows 2, so I would assume that the former is the case. Unfortunately, there must be something else going on here. I tried set kern.smp.disabled=1 at the loader prompt. It doesn't matter if I then 'boot -s' or simply 'boot', in both cases, the system never reaches the stage where I am prompted for the shell - it just hangs. If I detach and reattach peripherals, such as the keyboard, the console tells me so, but there is nothing else. I remember something (probably) similar happening a couple of years ago while trying to netboot NetBSD from the same box, and M. Dillon from DFly giving me the advice of setting the '-2' and '-r' mountd flags in rc.conf - which worked like a charm for NetBSD but didn't help at all in this case so I am kind of out of ideas. Does this sound remotely familiar and/or do you have any other suggestions? Thanks a lot, BR.- * Justin Hibbits <jhibbits@FreeBSD.org>: > Is this an SMP XServe, or a single CPU?
