AFAIK, ISA-PnP came a short time after PCI. Basically, since with PCI everything worked so fine by only plugging the card into your machine and it'd get set up correctly automatically, Microsoft and Intel got together to create a similar system for ISA. Thus, ISA-PnP was born. Where in the past you used jumpers (and then manually told your OS what you selected with these jumpers), ISA-PnP cards can be more or less automatically detected these days, although there sometimes still are problems. When PCI was first introduced with its autoconfiguration capabilities, I guess nobody used the words "plug-and-play". These were "invented" in order to try to tell people how esay Windows 95 was to use (?), by basically labelling every hardware component as "PnP".
