Line 88:
The hardware of PC computers additionally limited device expansion options because interrupts could not be shared, and some multifunction expansion cards would use multiple interrupts for different card functions, such as a dual-port serial card requiring a separate interrupt for each serial port.
 
Because of this complex operating environment, the [[autodetection]] process sometimes produced incorrect results, especially in systems with large numbers of expansion devices. This led to device conflicts within Windows 95, resulting in devices which were supposed to be fully self-configuring failing to work. The unreliability of the device installation process led to Plug and Play being sometimes referred to as ''Plug and Pray''.<ref>{{cite web
