UpToMP upgrades NT for multi-processor mode

If your Windows NT was installed with a single processor, the appropriate single
processor HAL and registry setting were used. You now want to add the 2nd
processor. If you have Compaq hardware, you can run the Server support
software, which you find in the NTSSD folder of your Compaq Smartstart CD. It
will give you a list of hardware omponents, select the uniprocessor HAL and
click the upgrade button. That’s all there is to it. If you have Compaq
If you don’t have Compaq hardware, there are three methods to
accomplish this (in order of preference):

  • Use Microsoft’s uptomp.exe from the Microsoft Windows NT Server 4.0 Resource Kit. The UpToMP
    utility will insure that NT is updated with the correct kernel and SMP
    compatible HAL. Since the service packs include updated HALs, extract the latest
    applied service pack into a folder. When UpToMP askes
    for the location of your HAL, don’t point it to the original NT installation
    disk but rather to where you extracted the latest SP.
  • Upgrading to
    Dual Processor NT 4.0/3.5x/TSE on i386.com
    has a manual upgrade process
    documented which takes advantage of %SYSTEMROOT%\repair\setup.log. When a
    service pack upgrade occurs, it uses the file listing here to determine which
    system files are present needing upgrading (at least in part). If you change the
    information in the setup.log to reflect the files found in the MP version of NT
    and re-apply your service pack, it will upgrade from uni-processor to dual
    processor mode for you. There are only 6 files different. The lines needing to
    change are: Note: there are many files in the [Files.WinNt] section – only
    the 6 critical files are listed]

    \WINNT\system32\hal.dll = “halapic.dll”,”1e1bd”
    \WINNT\system32\kernel32.dll = “kernel32.dll”,”5f6d7″
    \WINNT\system32\ntdll.dll = “ntdll.dll”,”63a98″
    \WINNT\system32\win32k.sys = “win32k.sys”,”13c422″
    \WINNT\system32\winsrv.dll = “winsrv.dll”,”37b4e”
    \WINNT\system32\ntoskrnl.exe = “ntoskrnl.exe”,”e197b”
    Those six lines need to be changed to:

    \WINNT\system32\hal.dll = “halmps.dll”,”1a01c”
    \WINNT\system32\kernel32.dll = “kernel32.dll”,”5f345″
    \WINNT\system32\ntdll.dll = “ntdll.dll”,”59c19″
    \WINNT\system32\win32k.sys = “win32k.sys”,”5f60a”
    \WINNT\system32\winsrv.dll = “winsrv.dll”,”301b3″
    \WINNT\system32\ntoskrnl.exe = “ntkrnlmp.exe”,”f52df”
    When you compare the list, you see that the CRC numbers for all the
    files changed. In fact, the CRC numbers above are for SP6a. If you are not
    upgrading to SP6a, you will have to check the setup.log on an MP box with the
    correct SP to get the proper CRC numbers. The CRCs change in each SP.
    Additionally you can see by comparing the before and after list, that the
    hal.dll used in uni-processor NT was halapic.dll and changed to halmps.dll and
    that the ntoskrnl.exe used changed from ntoskrnl.exe to ntkrnlmp.exe (that is
    single processor to mp versions).

    Make these changes. Set the attributes back to SHR, apply the SP, and reboot.
    Voila! your box is running MP. Note: If you compare my instructions to those
    at mpseasy.htm, there is an extra file listed, the winsrv.dll. Not sure why.
    Mine work on both workstation and server. Again, let me emphasize, the CRC
    values listed are for SP6a.
    I now prefer this
    method. Its definitely NOT recommended by Microsoft. Its the fastest. This
    method has a BIG advantage if you need to upgrade a bunch of servers or
    workstations quickly. If you are not sure of everything in this tip, stick to
    the uptomp method.

  • Perform an installation update – I have seen reports of this not working
    correctly. I suspect its related to using the original Windows NT installation
    disks with the rather old HALs found there.
  • Manually replace the HAL and update the appropriate registry entries. The
    process is documented in this
