Well, that's how UPS's are supposed to be used. In addition to Wake-On-Lan mentioned by Shimi, there are also: 1. Boot on AC power - i.e. if the AC power comes back then start reboot. That's a BIOS setting. 2. I think the smarter UPS's and BIOS also have something around "power X seconds/minutes after AC comes back", to avoid booting on spikes. --Amos _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
