TITLE :U.S. Service Pack 1 Overwrites OEM HAL
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:
----------------------------------------------------------------------
The information in this article applies to:
- Microsoft Windows NT operating system version 3.1
- Microsoft Windows NT Advanced Server version 3.1
----------------------------------------------------------------------
SUMMARY
=======
Your original equipment manufacturer (OEM) provided hardware
abstraction layer (HAL) can be overwritten by the U.S. Service Pack 1
for Windows NT and Windows NT Advanced Server version 3.1. If this
happens, your system may become unstable or may not start. Contact
your OEM or hardware vendor for more information on your particular
computer.
MORE INFORMATION
================
The HAL is the key to the hardware independence of the Windows NT. For
some non-standard hardware platforms or symmetric multi-processing
(SMP) computers, the OEM has provided a special HAL. Some of these
OEMs included such a HAL in the Windows NT package:
HAL.DL_ Most uniprocessor Intel x86-based systems
HAL486c.DL_ Intel x86-based PCs with the 486DX step C chip
HALAST.DL_ AST SMP systems in HCL
HALCBUS.DL_ Corollary Extended C-bus 486DX2/66 SMP system
HALMCA.DL_ MicroChannel Architecture systems
HALNCR.DL_ NCR SMP systems in HCL
HALOLI.DL_ Olivetti LSX5040
HALSP.DL_ Compaq SystemPro SMP systems in HCL
HALWYSE7.DL_ Wyse series 7000I SMP systems
During text-mode setup, by the type of computer you choose, Setup
determines which HAL to use. At this time you would choose the Other
option so that Setup prompts you for the OEM-provided HAL. Regardless
of the HAL used, Setup renames it to HALL.DLL. If you have an SMP
computer, NTKRNLMP.EXE is used and renamed to be NTOSKRNL.EXE. If you
do not have an SMP computer, the normal NTOSKRNL.EXE is used.
The Update program checks the SETUP.LOG file to see which files need
to be updated. If it detects that a the HAL was updated by an OEM, it
overwrites the HAL. This can result in additional processors not being
used or your system not booting.
If you experience this problem, please contact your hardware vendor. A
possible workaround would be to make a backup copy of the HAL.DLL
file. After the Update program finishes, copy the old HAL back over.
In any case, contact your OEM for more information on specific
considerations for your computer.
