PnP and Windows 95 to the Rescue
Plug and Play (PnP) eliminated the "plug and pray" frustration of manually configuring a PC when new peripherals were installed. In the mid-1990s, motherboards and peripherals began to support PnP, and Windows 95 was the first PnP-enabled OS. A PnP peripheral could also be used in a non-PnP computer by installing a system module (DWCFGMG.SYS).
Transitioning to PnP
If an older ISA peripheral card was installed in a PnP computer, the ISA Configuration Utility (ICU) looked up its requirements and configured the card's settings. If the card was not in the list, the ICU made recommendations for the user ("plug and tell"). See PnP-X
