Or do you mean PCI hot-plug? FreeBSD currently doesn't support powering off PCI slots or re-probing the PCI bus after bootup, both of which are required for hot-plug. I don't know how hard it would be to add, either. You'll probably have to ask -hackers about that (cc and reply-to reset there). -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
