Dual CPU, NT4 only sees one

[NullTerminator]

NT4 sp5 - originally installed on single cpu board. Now upgraded to dual cpu Abit VP6 with latest bios.

Bios reports two cpu's but OS sees only one. Do I have to tell the OS somehow?

I hope this can help

SYMPTOMS
When you upgrade a single processor computer with Windows NT 4.0 installed to a multiprocessor system, several files have to be changed.

The affected files are:
Ntoskrnl.exe (Ntkrnlmp.exe has to be copied and renamed to Ntoskrnl.exe)
Hal.dll (System specific Hal*.dll has to copied and renamed to Hal.dll)
Kernel32.dll
Ntdll.dll
Winsrv.dll
Win32k.sys (New for Windows NT 4.0)



CAUSE
Although Uptomp.exe from the Windows NT 4.0 Resource Kit does assist to copy the correct files, Win32k.sys is not copied with this utility.



RESOLUTION
To resolve the problem:


Locate the file Win32k.sys on the Windows NT 4.0 compact disc , and copy it to the System32 directory.

NOTE: The file might be compressed as Win32k.sy_. Use Expand.exe to uncompress the file.

You must then modify the %systemroot%\repair\setup.log file to modify the CRC value of win32k.sys to equal 13e42a - this value is for the multi-processor version and is used when installing future service packs or repairing the system files.

Note: If the customer already has a Service Pack loaded on the system he should point to the Service pack directory when the utility asks him for a path for the replacement files.


Modify the Resource Kit Uptomp.inf file and add the Win32k.sys to the list of files as follows:

hal.dll = 1, 2, hal.dll
ntoskrnl.exe = 0, 2, ntkrnlmp.exe
ntdll.dll = 0, 2, ntdll.dll
kernel32.dll = 0, 2, kernel32.dll
winsrv.dll = 0, 2, winsrv.dll
win32k.sys = 0, 2, win32k.sys

Thanks much for the prompt reply.

I have located uptomp.exe, my version includes win32k.sys in the inf file.

Did you try to recopy the files? Give that a try.

I used to do this for a few companies who had existing machines with one CPU and NT. The usual method of seeing the 2 processors was achieved by going through a re-install of the OS but using the upgrade option. This will get to where you want to be and in some cases which i think was almost all you may have to re-apply the service pack 6a if not done so already
