2nd Processor Not Recognized After Adding to Compaq Computer (111368)
The information in this article applies to:
- Microsoft Windows NT Server 3.1
- Microsoft Windows NT Workstation 3.1
- Microsoft Windows NT Advanced Server 3.1
This article was previously published under Q111368 SYMPTOMS
Windows NT and Windows NT Advanced Server do not recognize the second
processor after you upgrade a Compaq computer from a single processor to a
multiple processor.
CAUSE
When you install Windows NT on a Compaq computer with a single processor,
Setup installs the single processor version of the hardware abstraction
layer (HAL) and the kernel file. Then, when you add the second processor,
Windows NT does not recognize it. This differs from most multi processor
computers where Windows NT Setup installs the multi processor version of
these files and therefore recognizes the second processor automatically.
RESOLUTION
Follow these steps to install the multi processor HAL and kernel files on
your computer:
- Restart your computer and boot the MS-DOS operating system.
- Copy HALSP.DLL from your original Windows NT install disk(s) to the
<SystemRoot>\SYSTEM32 directory as HAL.DLL.
- Copy NTKRNLMP.EXE from your original Windows NT install disk(s) to the
<SystemRoot>\SYSTEM32 directory as NTOSKRNL.EXE.
- If you plan to use a kernel debugger, copy over the symbols files for
these files as well.
