NT4.0 PnP/full-duplex drivers installation notes 1. How to activate NT4.0 PnP functions? If your NT4.0 system PnP functions are inactive, you can use Windows explorer to find PNPISA.INF (it should be in NT4.0 CD directory \DRVLIB\ PNPISA\X86). Select it and press mouse right button. Select 'Setup' item, NT4.0 system PnP functions will activate, and the system will ask you to reboot the PC. 2. How to remove old audio drivers? If you have installed the old audio NT4.0 drivers, please remove WSS device in 'Audio Devices' of 'Advanced' page of 'Multimedia'. Shut down system to DOS, change directory to NT subdirectory INF, then search OEM*.INF files, delete our INF file. Delete all of old audio drivers in SYSTEM32 and SYSTEM32\DRIVERS subdirectory.
