You can not electrically determine which interrupts and address ranges and DRQ's are used by an ISA card. ISA cards must die for "Plug-N-Play" to ever completely work. Maybe if the new EISA slot refused to let the card on the bus without a configuration description, and then prevented the card from using anything but the bus resources allowed by the description. That type of active slot would be very expensive to implement just to obtain the ability to run $35 cards that are too shitty to allow you to raise the bus clock rate to 133MHz (to match your CPU) anyway. No, ISA cards must die. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
