Does NT support Plug and Play?

A. In a limited sense. There is a driver that can be installed that will detect Plug and Play devices, however it is not supported and you will receive no support. To install the driver

  1. On the NT installation CD, goto the DRVLIB/PNPISA/I386 (or whatever you processor)
  2. Right click on the file pnpisa.inf and select install
  3. Reboot the machine

Installing the driver sets the following registry values:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pnpisa\Enum\Type - 0x1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pnpisa\Enum\Start - 0x1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pnpisa\Enum\ErrorControl - 0x0
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pnpisa\Enum\DisplayName - "Pnp ISA Enabler Driver"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pnpisa\Enum\ImagePath - "system32\DRIVERS\pnpisa.sys"
