I have no clue about cardbus, but for PCI hotplugging you need hardware specific support to power down the slots. But hotplug PCI is not a realm of specific machines, as you can attach add-on hotplug frames to any PCI system. -- B.Walter BWCT http://www.bwct.de [EMAIL PROTECTED] [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
