Kidding? There's a standard for hot-swappable pci cards. you fire up a
command to "take down" the slot in question and when the LED on the slot
lights up it is safe to pull the card out and enter the new one. afterwards
you are giving a command to reenable the slot. The slot is powerless in
between and it _is_ safe to swap the cards then. Hot-swap pci slots are rare
and usually only found on expensive server mainboards.
I don't think the "slot up" and "slot down" commands are implemented in
OpenBSD, but i don't really know.
