Recognizing And Dealing With Conflicts 283

SYSTEM DATA AND TROUBLESHOOTING When the PnP system works properly, a PnP device can be installed in an available expansion slot on a PnP-supported motherboard (with a PnP BIOS. When Windows 95 starts, it recognizes the new PnP device, assigns resources, then attempts to install the proper protected-mode driver (which could be installed from manufacturer’s floppy disk or a Windows 95 installation CD. Thereafter, the system remembers the new device and reconfigures it each time the system starts. Ideally, if the PnP device is ever removed, Windows 95 would automatically clear the device from its system and free the resources for other devices However, if any of these elements are missing, devices will not be auto- configured For example, PnP won’t work under DOS (though there are DOS PnP drivers that can be used to initialize PnP devices. Older, jumper-configured devices (called legacy
devices) also won’t support PnP, and resources need to be reserved for legacy devices to prevent the PnP system from ignoring them entirely.
