If you have a non-PnP motherboard with ISA, your ISA slot devices that are not PnP *are active*. Period. If you are talking about PnP devices for which you don't have drivers, then you missed #7's "that were not marked disabled". This is the problem with continuing to use older ISA hardware.

Well, if you run out of interrupts and it doesn't let you disable on a per device on the board basis, you are still screwed, and I have to blame hardware (or trying to jam too much hardware into an ISA bus in the first place, or use of an ISA bus in the first place).
