JSI Tip 0642 - How do I add support for the HPFS file system?

Windows NT 4.0 does not support the HPFS file system unless it was installed prior to upgrading. If you wish to add support for HPFS to a new Windows NT install, copy Pinball.sys from the NT 3.51 CD or an existing computer to %SystemRoot%System32Drivers. Use Regedit on an existing Windows NT Platform that supports HPFS and export:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesPinball

Import it to your Windows NT 4.0 computer.
