To upgrade a single-processor system to a multiprocessor system, use Uptomp.exe. Uptomp.exe is included in the Resource Kit for Windows NT version 3.5. This tool is located under Performance and System Monitoring Tools in Resource Kit Tools Help.


The following list contains the computer models that appear in the Uptomp.exe tool and the associated HAL files included in Windows NT.

Note that the latest versions of these files are included in the Windows NT Service Packs. If you have installed a Service Pack, you should use the appropriate file from the Service Pack.

   halast.dll    = "AST Manhattan SMP"
   halsp.dll     = "Compaq SystemPro Multiprocessor or 100% Compatible"
   halcbus.dll   = "Corollary C-bus Architecture"
   halmca.dll    = "IBM PS/2 or other Micro Channel-based PC"
   halapic.dll   = "MPS Uniprocessor PC"
   halmps.dll    = "MPS Multiprocessor PC"
   halncr.dll    = "NCR System 3000 Model 3360/3450/3550"
   haloli        = "Olivetti LSX5030/40"
   hal.dll       = "Standard PC"
   hal486c.dll   = "Standard PC with C-Step i486"
   halwyse7.dll  = "Wyse Series 7000i Model 740MP/760MP"
After Uptomp finishes, you see a dialog box informing you that the upgrade was successful, the system needs to be restarted for this change to take effect, and that you should run Rdisk after the system restarts to update the saved configuration. It is very important to click the "Update Repair Info" option in Rdisk before you click "Create Repair Disk."

NOTE: If you are changing to or from single or multiple processors and you are using Microsoft Proxy 2.0 server on the same computer, you also need to replace the Ipfltdrv.sys driver (%systemroot%\system32\drivers). The single-processor version is 36 KB and is located on the Proxy 2.0 CD-ROM in the Msproxy\I386\Routing\Up folder. The multiple-processor version is 34 KB and is located on the Proxy 2.0 CD-ROM in the Msproxy\I386\Routing folder.
