I've come to the conclusion that certain components don't get a full reset unless you turn the damn thing off and then back on a few moments later. I've seen the keyboard lock up after using Ctl-Alt-Del to reboot from DOS to FreeBSD, and had other things go wrong after a shutdown -r and tgen booting DOS or NT (like the scsi controller not being found, etc). None of these conditions persist after a full reset. I'm not really sure how the x86 hardware works - what's the difference betewwn Ctl-Alt-Del and pushing the power button? Ideally, both would have the same effect, but that seems to not be the case. Also, when Freebsd halts and says 'press any key to reboot' or whatever, is it doing the same thing as ctl-alt-del? I've noticed problems after this too when I reboot, say, DOS. Now the screwy part is that all of this happens only on my Dad's PC (a Dell 486dx266, Adaptec 2842, #9gxe video card) and it has never happened on my PC (a generic AMD 486dx266, NCR scsi, WD svga card) -- Jeff Aitken jaitken@vt.edu
