How is it that BIOS settings can affect this? Do they fiddle with some battery-backed switch on the motherboard? I have an ATX system that must be looking for a keyboard-located power switch of some sort. It won't power up unless I unplug the (PS-2) keyboard, and then plug it back in again. That seems as though there's something fairly complicated in the system that _is_ being powered up. I think I'll try your hot-wiring trick. -- Andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
