Rolling a rack on carpet

I was thinking about how you switch back on, post pulling the power cord
out. When I put mine back in they don't all start back up until you press
the little ATX on/off button on the front. I guess it may be a BIOS thing,
but I can't find a setting that works.
I agree kickstart is ace.

Yanking the power cord works with nearly all past and present machines.
If you are patient and willing to wait for some machines internal UPS
(our AT&T 3B20 has biga** truck batteries in the back) to run down, the
percentage goes up. Of course it isn't really the best way, but it
works. I have no problems with it because any computational nodes that
get irrepairable software type problems from such an approach just get
reinstalled with "Dean's Magic Disk" (read "aint kickstart great"). ;-)
