When the power goes out, that will be the case... so, you get your break. There's not much you can do about that... Why is it that the power goes out on your 386 and not on your sun? Can you "plug" the PC into the same power source as your Sun boxes? Then, the PC won't go down until the Suns do... - Dave Rivers - To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
