In any case there are two major problems in my view: 1) to do automatic resource assignment you'd need to know which resources are available. Maybe the bios knows (more or less, since legacy isa devices with no driver cannot be easily detected, and the PnP detection of conflicts i am not sure how well it works), but i have no idea on how to fetch this info 2) providing a configuration in the kernel config file via "device..." entry is hard, since a single pnp device can have 8 io ports, 2 drq, 2 irq, 4 memory addresses ... how do you fit this info in the few bits available on the "device" line ? luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
