More the PnP protocol works exactly in this way: a card is idle until it is woken up in some way. Now, if a manufacturer devises a different wakeup protocol which is run _after_ the PnP conflict probe, you are in trouble. And many pre-isa-pnp cards had proprietary soft-config procedures. luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
