Some later ISA cards also supported "negotiation", iirc. It was marketed as plug and play, but often referred to as plug and pray (because sometimes the result would be less than useful). Also made DOS drivers downright massive!
I remember those 'Plug and Play' ISA cards. The PnP bit never worked, I eventually hard set the IRQ, IO port and DMA channel directly to get sound working, and that was that. At least, until the Windows95 install was messed up enough that it was time to reinstall again.
