SYMPTOMS
When you install Windows NT 4.0, Plug and Play devices in your computer
are not detected and installed.
CAUSE
Windows NT 4.0 does not support Plug and Play.
RESOLUTION
The driver library on the Windows NT 4.0 CD-ROM includes the PnP ISA
Enabler driver, which may allow the detection and installation of Plug
and Play devices in Windows NT 4.0. Install the PnP ISA Enabler driver
(PNPISA) using the following steps:
NOTE: Although Windows NT includes PNPISA to detect Plug and Play devices,
Plug and Play devices are not supported in Windows NT 4.0. PNPISA is
provided as a "use at your own risk" tool.
- Locate the Pnpisa.inf file in the Drvlib\Pnpisa\<processor-type> folder
on the Windows NT 4.0 CD-ROM.
- Right-click the Pnpisa.inf file, and then click Install on the menu
that appears.
- Restart your computer.
After you restart your computer, you may receive a message that Windows NT
has detected your Plug and Play device(s).
