I seem to remember Windows 95 and the quest for "plug 'n play" being what pushed the PCI standard into wide spread use. Basically the first standard that didn't require all the tedious mucking about with IRQ's, DMA and I/O Ports.

IIRC it was considered fashionable back in the day to install a card, wait for it not to work and then make a joke about "plug 'n pray" before finding an older, ISA card and getting it to work by setting the jumpers correctly.
