Ah, ok, I didn't quite get that from what you said, but yes, that's their advantage.
I've found that the presence of the card on powering up will not prevent my Amigas (three A1200s: two 1D4s and a 1D1) from booting - it just stops the card from being initialised properly, but Amigas are known for having strange quirks and differences even on the same revision of board.
