The information in this article applies to:

- Microsoft Windows NT Workstation version 3.51 
- Microsoft Windows NT Server version 3.51 
-------------------------------------------------------------------------------

SYMPTOMS
========

During Windows NT 3.51 Setup on a multi-processor computer, if you press F5
during the portion of Setup that displays the following text:

  Setup is inspecting your computer hardware

then this is the list of computer models that appears:

  AST Manhatten SMP
  Compaq SystemPro MultiProcesor or 100% compatible
  Corollary C-bus Architecture
  IBM PS/2 or other Microchannel-based PC
  MPS Uniprocessor PC
  MPS Multiprocessor PC
  NCR System3000 model 3360/3450/3550
  Olivetti LSX5030/40
  Standard PC
  Standard PC With c-step i486
  Wyse series 7000i model 740mp/760mp
  Other

This allows you to select the correct hardware application layer (HAL) for your
computer. If you select the incorrect option, you may get the following
message:

  The file HAL486C.DLL could not be loaded, Error code=4097


WORKAROUND
==========

To work around this problem, either:

- Install Windows NT using Custom Setup and verify that the computer type is
  identified as an MPS(Multimedia Presentation System) multi-processor personal
  computer.

  - OR -

- Run WINNT /OX to create a new set of floppy disks and rerun setup for
  automatic hardware detection.
