What needs to happen is } for if_ex to a little more selective about which addresses it } probes. While it is using a non-destructive probe (see } look_for_card()) it should also use the resource manager to check and see } if a port is assigned before it does anything else. Unfortunately the GENERIC kernel doesn't have a driver that could claim the ET card. Also ex_isa_identify() is called before the legacy ISA probes are done. IMHO, the best way to fix this would be for the dual-mode PnP/legacy drivers to identify any cards in PnP mode, then do legacy ISA probes using the old hard-wired port numbers, where legacy ISA probes can be controlled by userconfig. This is really ugly, but then we all agree that ISA sucks. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
