No it doesn't -- the BusLogic BT7xx cards are in no way shape or form
broken EISA cards.  They are perfectly functional EISA cards.  Sure
they have the weird ISA I/O address, but the card *can* still be
identified at its EISA address.

That's because you have a working EISA motherboard.  If 17MB works for
you, any EISA addressable range should work for you.  (I. e. you
wouldn't get 32MB, and nothing higher -- it should either be all or
