Pratically, giving the OS hints about ressources used instead of wiring down the PnP configuration gives me three advantages: - I expect to have only a few ressources that would need to be entered (that proverbial ArcNet card) - I can add additonal PnP cards without having to do the configuration chores again. - Most importantly: in the current scheme, there is no way of storing information about "reserved" resources (taken in h/w, but otherwise unused by FreeBSD) inside FreeBSD. So when you add an additional card half a year later, you already might have forgotten that ArcNet controller. Having it's resources listed as "reserved" might be helpful. Would it be so hard to have one or more "reserved" ISA devices, which you can add like any other device, and update throught the usual mechanisms? I'll take a look on the weekend...
